'0.4 A scheme for labelling environment friendly products to be known as ECOMark has been introduced at the instance of the Ministry of Environment andForests (MEF). The ECO Mark shall be administered by the Bureau of IndianStandards (8IS) under the BIS Act, 1986 as per the Resolution No. 71 dated 20February 1991, published in the Gazette of the Government of India. For aproduct to be eligible for ECO Mark it shall also carry Standard Mark of BISfor quality, in addition to the compliance with the optional environmentfriendly (EF) requirements. For this purpose, the Standard Mark of BIS wouldbe a single mark being a combination of the lSI Mark and the ECO logo.Requirements to be satisfied for a product to qualify for the BIS Standard Markfor ECO friendliness, will be included in the relevant published Indian Standardthrough an amendment. These requirements will be optional ; manufacturingunits will be free to opt for the lSI Mark alone also.

This amendment is based on the Gazette Notification No . 364 dated 7September 1995 for packaging material/package (part I Paper Board andPlastics Excluding Laminates) as environment friendly products , published inthe Gazette of India .This amendment is, therefore. being issued to this standardto include EF requirements for solid fibreboard boxes.'

Add 50 ml of ethanolicpotassium hydroxide solution and heat under reflux condenser for 4 h, filter anddilute to the mark with alcohol in a 250-ml volumetric flask. Take an aliquotportion of the test solution in a seperating funnel, add sufficient distilled waterand 15 ml hexane. Shake well for 5 minutes and wait for 15 minutes. Collect thehexane phase .

18


A-6.4.3 Filter the he xane extract. Dry the filtrate over anhydrous sodiumsulphate•. and evaporate under vacuum to approximately 5 ml. Take the residuefor clean up.

A-6.4.4 Clean Up

Transfer the hexane extract (A-6.4.3) to the silica gel packed column and elutewith about 25 ml of n-hexane at the rate of 2 ml/min . Collect the eluent in aflask and evaporate to a small volume. Add I ml of internal standard solutionand made up to IO ml with hexane.

A-6.4.5 Inject 2 ~I of the solut ion to the Gas chromatograph. From the peaksobtained PCB and Internal Standard are identified by their retention times aswell as relative retention time.

PCB content. mglkg on dry matter =M x VI X (100 - X)

A-6.4.6 Calibration

Prepare three calibration standards from the PCB standard solutions and followthe steps as above (A-6.4.3 to A-6.4.5). Tabulate peak height or area responsesagainst calculated equivalent mass of underivatized pentachlorophenolinjected. Prepare a cal ibration curve.

A-6.5 Calculation

Determine the PCB content of the sample from the calibration graph using thefollowing formula:

A x Vi X 100

whereA = PCB content in ~g from the graph ;Vi = volume of eluent injected, ml;M = mass of the paper sample taken in. g;VI = volume of total eluent. ml; andX = moisture con lent. percent by mass .

( First Revision )o. FO R E W 0 R D

0.1 .This Indian Standa~d ( Part II ) ( Fi~t Revision) was adopted by theIndian Standards Institution on 5 April 1975, after the draft finalizedby the Paper and Flexible Packaging. Sectional Committee had beenapproved by the Marine, Cargo Movement and Packaging DivisionCouncil.

0.2 Originally IS: 2771-1965 covered only corrugated fibreboard boxes.While revising IS: 2771-1965, it was decided to cover both corrugated andsolid fibreboard boxes in this standard. This revision is being issued intwo parts, Part I covering corrugated fibreboard boxes and Part II solidfibreboard boxes.

0.3 In the wake of the search for cleaner and simpler materials for thefabrication of transport packages the solid fibreboard boxes have come tobe wed in large numbers. Solid fibreboard boxes are wed to packmultiple of items differing widely in their shape, size, and mass. In addition to the functional features of solid fibreboard the other advantagesinclude minimum storage space, low labour cost in preparation for use, etc.

0.3.1 Solid fibreboard boxes are suitable both as primary packages aswell as transport packages for packaging a wide variety of commoditiesboth for domestic consumption and for export.

0.4 For the purpose of deciding whether a particular requirement of thisstandard is complied with, the final value, observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance withIS: 2-1960.. The number of significant places retained in the rounded offvalue should be the same as that of the specified value in this standard.

I. SCOPE

1.1 This standard (Part II) prescribes the requirements for solid fibreboard boxes for general packaging purposes, for weight up to 40 kg.

-Rulca for rOUDding off numerical vaJ1lCI ( misd).

1.2 lltis standard neither coven the requirements for waterproof!weatherproof solid fibreboard boxes nor for the solid fibreboard boxes withfibreboard bodies and wood-frames/solid wood ends.

2. TERMINOLOGY

2.1 For the purpose of this standard, the definitions given in IS: 42611967- and IS: 7186-1973t shall apply.

3. MATERIALS

3.0 The solid fibreboard boxes shall be manufactured from the followingmaterials.
