High Intensity Prismatic Refl ective Sheeting product bulletin

12 year performance guarantee and warranty statement

HIP is fi t for purposeSince its launch High Intensity Prismatic (HIP) Refl ective Sheeting has been extensively used by many specifi ers on signs used in a wide variety of road types and signing situations and has become the material of choice at Class Ref 2 performance level for many specifi ers.

Specifi ers have confi dently chosen HIP knowing that 3M had extensively tested it to ensure that it

met the performance requirements of all relevant standards,

• BS 873:part 6 Class 1 (BSI report number 247/4564727)

• BS EN 12899-1 Class Ref 2 (BSI report number 247/4619755)

• BS 8408:2005

Specifying HIP

Specifying Engineers at Local Authority and HA level have been free to write their own specifi cations

and request their own performance tables for retrorefl ective sheetings. That is how microprismatics

have been specifi ed prior to BS 8408 being published.

Local Authority specifi ers remain able to specify products they are satisfi ed are fi t for purpose

The Highways Agency (HA) is now revising the 1200 series documents to introduce BS 8408 as a

specifi cation tool. This will enable the HA to extensively use microprismatic materials such as HIP

and DG3.

In a recent communication the HA have stated:

If microprismatic material is specifi ed (in accordance with BS 8408: 2005) then the traffi c sign

shall be manufactured from microprismatic sheeting and the tests shall be in accordance with

BS 8408: 2005. In this situation, microprismatic signs have been specifi ed, so delivery of

microprismatic signs is acceptable to the HA.

This clearly shows that delivery and use of HIP signs is acceptable to the HA as long as the signface

material is specifi ed using BS8408: 2005 and the sign construction meets BS EN 12899-1: 2001.

Specifying HIP using BS 8408Specifi ers can use one or more of the BS 8408 scenario ratings below to specify a microprismatic sign sheeting that performs at the Class Ref 2 refl ectivity level:

Principal and motorway situations

D1 A1 V1 P1 LA ≥ 1.0 left hand mounted directional sign on 60 - 70 mph road - car

D1 A1 V2 P1 LA ≥ 0.4 left hand mounted directional sign on 60 - 70 mph road - truck

Primary Non-Trunk

D2 A1 V1 P1 LA ≥ 1.0 left hand mounted directional sign on 50 - 60 mph road - car

D2 A1 V1 P2 LB ≥ 1.0 right hand mounted symbolic sign on 50 - 60 mph road - car

Urban

D3 A1 V1 P2 LA ≥ 1.0 left hand mounted directional signs on 30 - 50 mph road - car

D3 A1 V1 P2 LB ≥ 1.0 left hand mounted symbolic signs on 30 - 50 mph road - car

D3 A2 V1 P1 LA ≥ 1.0 left hand mounted directional sign on 30 - 50 mph road - car

D3 A2 V1 P2 LB ≥ 1.0 right hand mounted symbolic sign on 30 - 50 mph road - car

Sign labelling All traffi c signs in the UK must be made to the construction requirements stated in the National Annex of BS EN 12899-1. Section 7.1.1 of BS EN 12899-1:2001 requires that fi nished signs bear a label which identifi es the performance class and month and year of manufacture. This has been regular practice in the UK for many years.

In the past signmakers have included microprismatic sign sheetings on these labels by using product

names (for example VIP, CG) or by using the word microprismatic on them. The preferred option is to

refer to the published British Standard for microprismatic sheetings (BS 8408) on these labels.

Anything and everythingHIP is proving to be a versatile sheeting for every situation. In Highways Agency Area 12, it’s being specifi ed for all replacement and new signing schemes, and even for temporary signing.

Area 12 of the Highways Agency covers the region from Leeds down to south of Sheffi eld, and from

the middle of the M62 out east to Hull and Grimsby. According to Andy Sturrock, a Senior Engineer

working for managing agent CarillionWSP, HIP is now the material of choice for all new signs in

the Area.

“We fi rst saw HIP very soon after its launch,” says Andy. “We were immediately impressed with

its refl ectivity and the fact that the cost so closely matched that of the existing beaded sheeting.

When you get better performance at the same price, what more do you want?”

At the time that HIP was launched, specifi cations were written against BS873, but now it’s BS 8408

that matters. “The standard lets us assess the suitability of sheeting for every situation,” says Andy.

“HIP consistently exceeds our requirements and we’re very happy to use it”.

HIP HIP hooray Making life easier for the sign shop is just one of many advantages of specifying HIP.

In the spring of 2006, Northumberland County Council Sign Shop took delivery of its fi rst

consignment of 3M High Intensity Prismatic sheeting. The difference and improvement compared

with glass bead material was immediately apparent to all those who had to work with it.

“It’s a much easier material to handle,” says Sign Shop Foreman, Geoff Steanson. “Glass bead

material is likely to crack as soon as you bend it, but the HIP is much more tolerant and resistant

to damage. HIP also has excellent trimming qualities along the edge of the sign plate.” From a

practical perspective, that makes HIP much nicer to work with. Longer term, the sign shop should

also see cost and effi ciency gains through a reduction of damage in the workshop.

And talking of longer term, there’s a 12 year guarantee with HIP, compared with a ten year guarantee

for beaded sheeting.

“Even just working with the material in the sign shop we could see that HIP is much brighter than

the beaded material,” adds Geoff, “but there’s another feature to it that means we’re much more

confi dent of producing a high quality sign when we use the HIP. The face of the material has a

straight line pattern and is beautifully smooth. That makes it much easier to align and affi x the letters

and symbols that make up the sign information. The glass bead sheet that we used to get from

another supplier was uneven and that could lead to bubbling under the vinyl. The smooth surface of

the HIP means that you get a much better fi nish and long term I’m confi dent that the signs will look

better and last longer when out on the road.”

Chalk and cheeseStandard Signs and Traffi c Systems Ltd took an instant liking to HIP and now the Newport-based company won’t use anything else.

It was about 18 months ago that Standard Signs and Traffi c Systems Ltd was invited to trial HIP.

It was a trial that brought an immediately positive response from the company’s managing director.

“Compared with the beaded materials it was so much easier to work with and gave a much better

fi nish,” says Sam Hassani. When pressed for a little more detail, “it’s the colour difference that

comes shining through”.

“The fi nished articles are like chalk and cheese,” says Sam. “We’ve used a variety of beaded

sheetings and when you put any of them against a sign made with HIP the difference is

really obvious. With beaded sheeting a white is always going to be off-white. But with HIP the

white is defi nitely white. The HIP is fresher, brighter, and given the extended guarantee, from the

customer’s perspective the HIP wins every time.”

Coupled with the fact that the HIP is priced right there with the beaded material, it’s been an

easy decision for Sam to commit to using HIP for all the Class Ref 2 signs the company supplies.

“Just before HIP came out, we’d already decided to use 3M materials exclusively,” he confesses,

“but the HIP made that decision so much easier. It’s nice to have a new product for everyday signage

that doesn’t break the bank. From the word go, the HIP has been competitively priced and we’re

now supplying it as a matter of course every time. Our customers are very happy and I can say with

absolute certainty that no-one has asked us to go back to using the beaded materials!”

What more could you want?3M™ High Intensity Prismatic (HIP) refl ective sheeting is now fi rmly established as the best all round sheeting in the market at Class Ref 2 performance. It’s been used in many signing projects and everyone can see the difference it’s making. Now, with the introduction of BS 8408 (see over), it’s even easier to specify HIP whenever Class ref 2 performance is required.

As one Senior Engineer put it, “We use HIP because it is better overall. What more do we want?”

What more indeed? The fact, HIP gives you so much more.

Compared to beaded products, HIP:

• Is brighter in daylight

• Is brighter at night in many common situations

• Has sharper colours, especially whites

• Is easier to handle

• Is resistant to cracking

• Has a smoother surface

• Is guaranteed for twelve years not ten

• Is the same price or less!

Environmental Benefi ts

HIP has been designed to minimize environmental impacts from manufacturing to disposal.

The product is constructed through lamination of layers with minimal solvent use or emissions, whilst

long service life minimizes sign replacement.

The great all-round performance of HIP means that everyone benefi ts:

• Drivers are alerted more quickly to hazards, and

have longer to make their decisions. High performance

signs using HIP can really help with accident reduction,

especially when driving conditions are dangerous.

• Signmakers have a material that’s easier to work with

and resistant to damage in the workshop. There’s less

risk of rejection, the sheet won’t crack if bent, and the

smooth surface makes it easier to apply the lettering.

As a signmaker told us, “It’s like the difference

between chalk and cheese.”

• Specifi ers provide a sign that works harder, day

and night, but costs no more than a beaded sign.

The 12 year guarantee means that investment is

protected for longer helping acheive best value

for clients.

Your choice is an easy choice

BS 8408 allows transport engineers to specify signs from

the driver’s perspective and to ensure that minimum

luminance criteria are met. It also allows specifi ers to

assess different materials to determine whether they meet

the luminance criteria or not.

Hence BS 8408 permits an engineer to specify HIP with

confi dence, knowing that best value and drivers needs are

well met.

BS 8408:2005The new British Standard for Microprismatic Sheeting (BS 8408:2005) is ground-breaking in that it is one of the fi rst to be written from the perspective of the driver, rather than how the products perform as they leave the factory. It’s vital that road traffi c signs are bright enough to ensure a signifi cant proportion of drivers can see and react safely to them. The standard describes this luminance need (sign brightness) and rates how well a sign sheeting satisfi es that need.

BS 8408:2005 looks at aspects of driving scenarios that can affect a drivers ability to see and

use signs

• Different types of vehicles they drive

• Different Road speeds / distances / reading times

• Different sign types

• Different sign positions and angularity

• Amount of ambient lighting

BS 8408:2005 rates retrorefl ective performance based on how bright drivers need a sign to be.

It defi nes the minimum luminance needed by drivers to recognise, read and react safely to traffi c

signs and rates how well a sign sheeting satisfi es this luminance need.

Specifi ers can use the standard either to set a specifi ed luminance performance for a sign or to

determine from the sheeting manufacturers test results whether it meets their requirements.

Taking all these factors into account, BS 8408 provides a way to rate how well a microprismatic

sheeting satisfi es the needs of drivers for many frequently occurring situations.

Using this rating system, road authorities can specify microprismatic sheeting

with confi dence.

Application 3M™ High Intensity Prismatic Reflective Sheeting Series 3930 has a pressure-sensitive adhesive that should be applied at room temperature (18 - 28°C) or higher by any of the following methods:

1. Mechanical squeeze roll powered laminator 2. Hand squeeze roll applicator 3. Hand application Hand application is recommended for legends and copy only. Application of sheeting for backgrounds must be done with a laminator. Series 3930 sheeting should be butt joined when more than one piece of sheeting is used on one piece of substrate. The sheeting pieces should not touch each other at the join and a gap of 1 to 1.5 mm is recommended to prevent buckling as sheeting expands in extreme temperature /humidity exposure. Substrates For traffic sign use, properly prepared aluminium and British Steel HP200 are the only substrates on which this product is warranted by 3M. See Instruction Bulletin 1.5 for recommended substrate preparation.

Users are urged to carefully evaluate all other substrates for adhesion, flatness, resistance to warping and sign durability. Sign failures caused by the substrate or improper surface preparation are not the responsibility of 3M. Plastic substrates are not recommended where cold shock performance is essential. 3M High Intensity Prismatic reflective sheeting is designed primarily for application to flat substrates.

Process Colours 3M High Intensity Prismatic reflective sheeting with pressure sensitive adhesive may be processed into traffic signs by screen printing, before or after mounting on a sign substrate, using 3M™ Process Colour Series 880I (see Product Bulletin 880I).

Series 880I can be screen processed at 16-28°C at relative humidity of 30-60%. Use of 61T/62T screen mesh with a fill pass is recommended.

Use of other process colours is not recommended. 3M assumes no responsibility for failure of sign face legends or backgrounds that have been processed with non-3M process colours or 3M process colours other than Series 880I.

Care should be taken to avoid creasing or folding High Intensity Sheeting Series 3930 before and after screening to eliminate the possibility of cracking from improper handling techniques. Edge Sealing Edge sealing 3M High Intensity reflective sheeting is generally not required. Following outdoor exposure, dust particles may become trapped within the row of cut cells along the sheeting’s edge. This should not adversely affect the performance of the rest of the applied copy. Narrow width markings or letters should be a minimum of 18mm stroke width. Where possible screen printing or 3M ElectroCut™ Film is recommended. 3M™ ElectroCut™ Film Series 1170 As part of the 3MTM Matched Component SystemTM, ElectroCut Film can be applied over 3M High Intensity Prismatic reflective sheeting using 3M TPM5 Transfer Tape. ElectroCut Film is especially suitable for small quantities of signs where screen printing may be uneconomic.

PB3930 March 2007 Page 3 of 4

Cutting and Matching

3M High Intensity Prismatic reflective sheeting may be hand cut or die cut one sheet at a time, and band sawed or guillotined in stacks. The sheeting can be hand cut from the face side with a sharp knife or other sharp hand tool. Cutting equipment such as guillotines and metal shears that use pressure plates to hold the sheeting when cutting may damage the optics. To reduce pressure on and eliminate damage to the sheets the pressure plate should be padded. Stack heights may vary with condition and type of equipment used, but should not exceed 50 sheets. NOTE: As with all reflective sheetings, when two or more pieces are used side by side on a surface they must be matched to assure uniform daytime colour and night appearance. Prespacing Use 3M™ Scotchcal™ Prespacing Tape Series SCPS-100 as a carrier for die cut letters, numerals or symbols for rapid, accurate application of legends. Cleaning Signs that require cleaning should be flushed with water, then washed with a dilute solution of mild, non-abrasive detergent and soft bristle brush or sponge. Avoid pressure that may damage the sign face. Flush with water following washing. Do not use solvents to clean signs.

Note: Signs covered with 3M Dew Resistant overlay must be flushed with clean water only. Detergents must not be used. Storage 3M High Intensity Prismatic reflective sheeting should be stored in a cool, dry area, preferably at 18-28°C and 30-60% relative humidity and should be applied within one year of delivery.

Rolls should be stored horizontally in the shipping carton. Partially used rolls should be returned to the shipping carton or suspended horizontally from a rod or pipe through the core. Unprinted sheets should be stored flat. Unmounted-screened faces must be interleaved with SCW-82 slipsheet, glossy side against the sign face.

Indoor Storage of Finished Signs

Finished signs and applied blanks should be stored face to face, on edge on wooden battens. Signs must be protected with SCW-568 slipsheet paper or with the plastic liner. Place the glossy side of the protective layer against the sign face. Double-faced signs must have the glossy side of the slipsheet against each face of the sign.

Outdoor Storage of Finished Signs

If outdoor storage is necessary, remove all packaging and store face to face, on edge on wooden battens with a gap between the signfaces to allow air movement.

Signs kept in metal containers must be stored as above for outdoor storage.

Panels or finished signs must remain dry during shipment and storage. If packaged signs become wet, unpack immediately and store as for outside storage to allow signs to dry.

Avoid banding, crating, or stacking signs or faces. Package for shipment in accordance with commercially accepted standards to prevent movement and chafing.

Effective Life The effective life of 3M High Intensity Prismatic reflective sheeting will depend on substrate selection and preparation, compliance with recommended application procedures, weather exposure and maintenance.

Permanent static road traffic signs incorporating 3M High Intensity Prismatic reflective sheeting applied to aluminium or British Steel HP200 substrates which have been prepared according to 3M recommended procedures, have an expected performance life of 12 years when mounted vertically.

Application to sign substrates other than aluminium or British Steel HP200 or preparation of aluminium in ways other than recommended may shorten the effective life. Application to unprimed, excessively rough or non-weather resistant surfaces will shorten the effective life. The user must determine the compatibility / suitability of any other substrates for the intended use.

Under certain conditions effective life may be shorter due to sign location, climatic conditions and method of installation.
