2 Introduction Intertek Testing Services NA, Inc. (Intertek) has conducted testing for Structurlam Products LP, on their CrossLam® CLT Un-restrained Load-Bearing Floor/Ceiling Assembly, to evaluate its fire resistance. Testing was conducted in accordance with and following the standard methods of ASTM E119�16a, Standard Test Methods for Fire Tests of Building Construction and Materials, and CAN/ULC S101, Standard Methods of Fire Endurance Tests of Building Construction and Materials, Fifth Edition, dated June 2014. This evaluation was completed on February 22, 2017.

3 Test Samples 3.1. SAMPLE SELECTION

Samples were randomly selected between the dates of January 25-26, 2017 by Intertek representative Dan Lungu, at the Structurlam Products LP manufacturing facility, located at 1675 Maple Street, Okanagan Falls, BC, V0H 1R2, Canada. The three pre-built CLT floor assemblies were received at the Evaluation Center on February 2, 2017 (Intertek Sample ID No. SAT1702020808-001). Other materials for the gypcrete floor were received between the dates of February 1-2, 2017, and assigned Intertek Sample ID Nos. SAT1702011247-001, -002 (adhesive and fiberglass composite mesh); SAT1702021045-001 (mixing sand). The subject test specimen is a traceable sample selected from the manufacturer's facility. Intertek selected the specimen and has verified the composition, manufacturing techniques and quality assurance procedures.

3.2. SAMPLE AND ASSEMBLY DESCRIPTION The three pre-built floor/ceiling assemblies consisted of cross-laminated timber, plywood splines, connection hardware, fire caulk, and a commercial topping floor. 1. Floor Assembly � Structurlam Panel Type 175 E, PRG-320 Grade E1M5, 5 layer CrossLam®

CLT panels produced from a glued-up CLT Mass Timber combination of 2×6 SPF MSR 2100 in all major strength (span) direction layers, and 2×6 SPF #2 and better in all minor strength (cross span) direction layers. Three (3) separate CrossLam® CLT panels were fastened together via a spline connection (see #2 above and drawing in Appendix A). Prior

to securing each section to each other using ratchet straps, one side of each vertical step down joint was coated with Hilti FS-ONE MAX #2101531 High Performance Intumescent Firestop Sealant. The sealant was putty-knife applied to fully cover one side and be uniform in thickness as much as possible. The sections were then secured together using ratchet straps until the sealant smeared out of the joint (no gaps).

2. Plywood Splines � 19 mm thick × 139 mm wide (nominal 3/4 in. thick × 5-1/2 in. wide)

plywood splines were inserted into the open slots of each of the two sections.

3. Securing Hardware – SWG ASSY Plus VG CSK fully threaded, zinc coated, AW 40 screws with drill tips were installed at 100 mm on-center (oc), staggered, at 15° angles. The client supplied a jig for proper angle installation.

4. Commercial Topping – 40 mm (1-1/2 in.) thick of Maxxon® Corporation Gyp-Crete® 2000™

Special Gypsum Cement Board Underlayment Compound pumped onto the top of the sample. Small pieces of plywood board were used to dam the top of the floor section in order to obtain the 40 mm thickness. Before the underlayment compound was pumped, the top of the CLT floor was reinforce with Maxxon® Reinforcement underlayment mesh screen, fully stapled onto the CLT floor. Additionally, the CLT floor was prepared by spraying Maxxon Acrylic Adhesive on top of the mesh. Work was performed and completed by representatives from G.L. Nettles, Inc. on February 3, 2017.

A 6 in. × 6 in. steel reinforcing angle was welded together around the perimeter of the floor sample in order to properly lift and move it. The sample was left undisturbed and allowed to cure at laboratory ambient temperature.

4 Testing and Evaluation Methods

4.1. INSTRUMENTATION The unexposed surface of the assembly was instrumented with a total of eleven (11), 24 GA, Type K, fiberglass jacketed thermocouples: TCs 1 - 9 were evenly distributed across the floor assembly as described in the standards; TCs 10 and 11 were installed over each of the butt-joint sections. The output of the thermocouples and the furnace probes were monitored by a 300-channel Yokogawa, Inc., Darwin Data Acquisition Unit. The computer was programmed to save data every 30 seconds. Following the test, the files were imported into MS Excel for tabular and graphical display (presented in Appendix C).

4.2. TEST STANDARD Testing was conducted in general accordance with the applicable requirements of ASTM E119�16a, Standard Test Methods for Fire Tests of Building Construction and Materials.

4.3. TEST STANDARD Testing was conducted in general accordance with the applicable requirements of CAN/ULC



S101, Standard Methods of Fire Endurance Tests of Building Construction and Materials, Fifth Edition, dated June 2014. The assembly was installed on the full scale horizontal furnace with the cross-laminated timbers facing the exposed side of the furnace, and tested to the time-temperature curves outlined in ASTM E119-16a and CAN/ULC S101-14.

5 Testing and Evaluation Results 5.1. RESULTS AND OBSERVATIONS The test was initiated on February 22, 2017. Nicholas Sills, representing Structurlam Products LP, was present to witness the test. The ambient temperature at the time of the test was 25 °C (77 qF) and the humidity was 33 % R.H. Prior to the start of the test, the relative humidity of the CLT was measured at 12 different locations and recorded to be between 8-9%. The test assembly was loaded to a client supplied reduced live load of 3.6 kPa (75 psf), evenly distributed over the whole assembly, using hydraulic cylinders [NOTE: The dead load supplied by the 40 mm (1-1/2 in.) thick topping of Gyp-Crete® was calculated to be 0.75 kPa (15 psf). In turn, the total load of the assembly was 4.35 kPa (90 psf) + the self weight of the assembly.]. The loading of the sample was conducted via the general guidelines of Section 7.2.1 of CAN/ULC S101-14. Once the load was fully applied, it was allowed to stabilize on the sample for a minimum 30 minutes prior to the start of the fire test. Observations made during the test are listed below: Time (min:sec) Observation(s)

The test was terminated at 150 minutes due to possible structural collapse of the floor. The floor/ceiling assembly withstood the fire endurance test without passage of flame or gasses hot enough to ignite cotton waste for the 150 minute duration. Transmission of heat through the floor/ceiling assembly during this duration did not raise the average temperature on the unexposed surface more than 140 °C (250 °F), nor any individual unexposed temperature more than 180 °C (325 °F) from the starting ambient temperature. The deflection of the floor assembly was measured at the mid-span of the sample. The deflection is presented in the table below:

In Equation 1, C is the correction factor, I is the indicated fire resistance period prior to modification with the correction factor, A is the area under the furnace average curve for the first 3/4 of the indicated fire resistance time, As is the area under the standard curve for the first 3/4 of the indicated fire resistance time, and L is a lag correction factor equal to 3240 °F•min. The correction factor was added to the indicated fire resistance period, yielding the corrected fire resistance period achieved by the specimen (see table below): Correction Factor for the Fire Endurance Test

6 Conclusion Intertek Testing Services NA, Inc. (Intertek) has conducted testing for Structurlam Products LP, on their CrossLam® CLT Un-restrained Load-Bearing Floor/Ceiling Assembly, to evaluate its fire resistance. Testing was conducted in accordance with and following the standard methods of ASTM E119�16a, Standard Test Methods for Fire Tests of Building Construction and Materials, and CAN/ULC S101, Standard Methods of Fire Endurance Tests of Building Construction and Materials, Fifth Edition, dated June 2014. This evaluation was completed on February 22, 2017. Based on the results of this test, the CrossLam® CLT Un-restrained Load-Bearing Floor/Ceiling Assembly described herein sustained an applied reduced live load of 3.6 kPa (75 psf) throughout the 150 minute test duration [NOTE: The dead load supplied by the 40 mm (1-1/2 in.) thick topping of Gyp-Crete® was calculated to be 0.75 kPa (15 psf). In turn, the total load of the assembly was 4.35 kPa (90 psf) + the self weight of the assembly]. Transmission of heat through the floor/ceiling assembly during this duration did not raise the average temperature on the unexposed surface more than 140 °C (250 °F), nor any individual unexposed temperature more than 180 °C (325 °F) from the starting ambient temperature. No flaming was observed on the unexposed side of the assembly for the 150 minute test duration. In turn, the assembly described herein achieved a fire resistance rating of 150 minutes.
