4、et sections. Suspend test samples with 6 mm of foam in an air circulating oven at 120 +/- 2 C for 21 days. Remove and condition 24 h at standard atmosphere. 3.6.1 Color Stability Rating 3 (AATCC Evaluation Procedure 1/ISO 105-A02) After exposure, material shall show no evidence of tackiness, spewing

5、, or exhibit staining, color tone change, or change in hue in excess of specified Gray Scale rating. Any spotty or non-uniform staining or discoloration shall be cause for rejection. 3.6.2 Cold Flexibility No cracks (180 bend at -30 C over a 19 - 20 mm diameter mandrel, specimen size 50 x 150 mm) Re

7、s defined in para 3.6) After exposure in accordance with 3.7.1, 3.7.2, and 3.7.3, the material shall not stain, exhibit color tone change or change in hue in excess of specified Gray Scale rating (AATCC Evaluation Procedure 1/ISO 105-A02). In addition, there shall be no cracking, crazing or other de

8、terioration. The material must remain flexible and exhibit no cracking when bent around 19 - 20 mm mandrel after specified exposure. Remove foam and bend with foam side of skin to mandrel. A slight loss of gloss or chalking will be allowed provided an acceptable appearance can be achieved by washing

9、 with mild detergents and water (ratio 5:95 by volume), or equivalent, after the Florida exposure only. All initial approvals will be based on the preliminary Weatherometer exposure, pending Florida and Arizona exposure results for final approval. ENGINEERING MATERIAL SPECIFICATION WSB-M4D740-A2 Cop
