PRODUCT RANGE CLEAN SYSTEMS Load and Impact Testing FM4882 Standard ACS ceiling panels are tested by both in-house testing facilities and independent third-party test centres. Examination Standard for Class 1 Interior Wall and Ceiling Materials or Systems for Smoke Sensitive Occupancies Load Testing Report This standard applies to interior wall and ceiling materials or systems used in cleanrooms, pharmaceutical manufacturing and storage areas, food preparation and storage areas and similar occupancies or other occupancies which are susceptible to smoke damage. Dated 27 September 2019 EVOClean MODULAR CEILING SYSTEM FOR CLEAN AND STERILE ENVIRONMENTS The EVOClean is a non-walk-on suspended ceiling system designed specifically for cleanroom applications. Wall and ceiling materials or systems which are categorized for use in cleanrooms meet the requirements of Examination Standard for FM Approvals Cleanroom Materials Flammability Test Protocol, Class Number 4910 and American National Standard for Clean Room Materials Flammability Test Protocol ANSI/FM Approvals 4910 in addition to the other requirements of this standard. These materials or systems produce low levels of smoke. Dated 27 September 2019 Note: This report is issued subject to the Testing and Certification Regulations of the TÜV SÜD Group and the General Terms and APPENDIX A Conditions of Business of TÜV SÜD Malaysia Sdn Bhd. In addition, this report is governed by the terms set out within this report. Photo 1: Test Samples SUBJECT: Load test for 50mm panel ceiling system. TESTED FOR: Astra Technologies DATE OF TEST Suitable for both negative and positive pressure regimes, sterile and non-sterile environments, the EVOClean is the opportune solution for cleanrooms, laboratories, research centres and healthcare applications. The integrated LED lighting results in a completely flush finish for easy cleaning, with the absence of grooves and crevices preventing any build up of dirt and risk of contamination. Wall and ceiling materials which meet the requirements of this Standard and which are categorized for use in pharmaceutical manufacturing and storage areas, food preparation and storage areas and similar occupancies produce somewhat higher levels of smoke (when compared to those materials or systems which were evaluated for cleanrooms) but produce less smoke than materials and systems evaluated to the Examination Standard for Class 1 Fire Rating of Insulated Wall or Wall and Roof/Ceiling Panels, Interior Finish Materials or Coatings, Class Number 4880 or Examination Standard for Class 1 Exterior Wall Systems, Class Number 4881. 6 September 2019 / 17 September 2019 DESCRIPTION OF SAMPLES Photo 2: Test Setup One unit of ceiling system said to be model: 50mm thick aluminium core with 0.5mm thick steel skin aluminium (M Frame); Size: 1195mm (W) x 1195mm (H). (Refer to photo 1 appendix A and appendix B for client’s engineering drawing) TEST METHOD The aluminum ceiling grid which was suspended from a steel structure by means of 4 pieces hanger rod Uniform Load Test: One piece of panel was placed on the steel structure and was subjected to a load through a 70mm x 190mm rectangle indenter via a hydraulic cylinder at the center of the panel. A linear displacement transducer was positioned at the underside of the loading location to measure deflection. The load was applied in 1-minute steps of 500N, 1000N, 1500N, 2000N, 2500N, 3000N and released to zero load. The residual deflection at zero load was measured after 5 minutes. Test to Failure: The load was applied in 1-minute steps from 3500N with the increment of 500N until failure. The deflection readings are not taken. Subject to any abnormalities found during the increment of the load, the test will stop and record the result. Applications: • Regional Head Office: TÜV SÜD Asia Pacific Pte.
