Work Item
ASTM WK91034
Revision of C1574-04(2018) Standard Guide for Determining Blown Density of Pneumatically Applied Loose-Fill Mineral Fiber Thermal Insulation
Rationale
Section 7.1.12 instructs users to use compressed air to blow insulation away from the moveable test chamber to achieve a level surface. This use of compressed air may unnecessarily disturb or compromise the sample. There has been discussion around making this step/section optional for users, if it can be done without compromising the sample/material.
