Product Code:SAE J1351
Title:Hot Odor Test for Insulation Materials
Issuing Committee:Acoustical Materials Committee
Scope:This test applies to various materials used for insulation and other applications.The purpose of this test is to evaluate and compare the odor characteristics of various trim and insulation materials and composites. Odor is a difficult property to quantify. Therefore, the data from this test are probably most useful when compared to data obtained from samples with known odor characteristics.【英文标准名称】:StandardPracticeforSolarSimulationforThermalBalanceTestingofSpacecraft
