Research Report RR:C16-1032
An interlaboratory study on the breaking load and flexural properties of block-type thermal insulation was conducted in 2005 to establish precision statements for C203. The eight laboratories participating in the study measured the breaking load/flexural property of five randomly selected samples of four different block-type EPS/XPS thermal insulations at two different cross-head speeds.
