Standard Practice for Conditioning of Thermal Insulating Materials
 N C870

Annotation

This practice covers the conditioning of thermal insulating materials for tests. Since prior exposure of insulating materials to high or low humidity will affect the equilibrium moisture content, a procedure is also given for preconditioning the materials.

The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Общепринятая практика для создания условий тепловых изоляционных материалов

Эта практика покрывает создание условий тепловых изоляционных материалов для тестов. Так как предшествующее воздействие изоляционных материалов к высокой или низкой влажности будет влиять на влажность равновесия, процедура также дана для предварительного создания условий материалов.
