Annotation of standard text ASTM E1730-19 :

This specification covers rigid closed-cell polyurethane and polyisocyanurate thermal insulation foams for application in sandwich structural panel cores used in shelter construction for exposure to specified ambient temperatures. The unfaced foam thermal insulation boards are classified into three types (Types 1, 2, 3, and 4) according to increasing nominal density. The morphology of the insulation shall consist of a multitude of individual cells of uniform size and dimension, essentially closed off from each other, homogeneous throughout, free of voids, accumulations of unexpanded material, foreign inclusions, or seams. Upon undergoing appropriate acceptance tests, sampled specimens should adhere accordingly to the limiting values set for the following physical and mechanical properties: density; thermal conductivity; compressive strength; shear strength; percent closed cell; linear and volumetric dimensional stability; flame resistance (extinguish time and burn distance); and impact resistance.
