Research Report RR:C16-1022
An interlaboratory study was conducted by seven companies testing material from a production run of one product. Each received approximately 1000 pounds of product. A series of three tests were conducted at different weights persq.ft. (.575, 1.150, 1.575). Each weight was blown and measured immediately after three times, and an average thickness was determined to establish a precision statement for Test Method C1374.
