U Table 02771.2 Properties for Textured HDPE Geomembrane Notes: 1. The results obtained from D5994 will be an average of all readings taken, this result must meet or exceed the specified value for minimum average thickness. In addition, all individual readings taken to obtain the average cannot be less the specified average thickness requirement. 2. Other methods such as D4218 (muffle furnace) or microwave methods are acceptable if an appropriate correlation to D1603 (tube furnace) can be established. 3. Carbon black content is only measured on the black backing of the white -surfaced geomembrane, if applicable. Prior to measuring the carbon black content, the white surface shall be scrapped or ground off to avoid misrepresentative results in the final result. Contact the manufacturer for an approved method of testing. 4. Carbon black dispersion for 10 different views: All 10 in Categories 1 or 2 5. The manufacturer has the option to select either of the OIT methods listed to evaluate the antioxidant content in the geomembrane. 6. The condition of the test shall be 20 -hr UV cycle at 75 deg. C followed by 4 -hr. condensation at 60 deg. C. 7. UV resistance is based on percent retained value regardless of the original HP-OIT value. 0:%an Joaquin CountyWCRCSL11312301pina1 - Desi9n Mod 51Tech SpeWNCRCSL_TS_Module 5-Fina1-Rev_doc-00: SHAW ENVIRONMENTAL, INC.
