Revision of C739-21a Standard Specification for Cellulosic Fiber Loose-Fill Thermal Insulation

Rationale

Section 11 Fugi resistant was substantial changed in a previous ballot. The change removed the test method and referenced C1338 but left the sampling instructions in C739 due to the unique nature of the material. There is still some questions regarding the sampling procedure and parts of section 11 are redundant with C1338. This ballot clarifies the sampling procedure and removes the redundancies. Specifically sections 11.2.4, 11.3 and 11.4 are redundant with C1338 and are not needed. The sample collection is now better defined and a range of sample size (+/-) has been added. Only the section shown is open for ballot.
