5、r Production Materials (WSS-M99P1111-A). 3.1.1 Many 4D resin specifications prior to 2011, identified certain requirements with the symbol (s), which indicated that the mean and +/- 3 sigma values were to be reported. The specification minimum, maximum or range was established using 3 sigma data. Fo
6、r 2011 and beyond, refer to Table 1 for number of samples required for each test to establish specification limits. 3.1.2 WSS-M4D729-B5 is based on virgin materials. 3.1.3 WRS-M4D729-B6 must contain XX% Post Consumer Recycled (PCR) and/or Post Industrial Recycled (PIR) content as defined by WRS-M99P
7、42-A1. The remaining portion of the material can come from virgin sources. 3.1.4 The use of regrind is permitted for economic and environmental reasons with compliance as indicated in WSS-M99P1111-A. 3.1.5 Materials used in interior applications must meet the requirements outlined in WSS-M99P2222-C1
