MIL-STD-1411A, DEPARTMENT OF DEFENSESTANDARD PRACTICE: INSPECTION AND MAINTENANCE OF COMPRESSED GAS CYLINDERS (22 JUL 2002)., This standard defines the requirements and procedures for the inspection, maintenance, and charging of government-owned cylinders by gas suppliers. This standard is intended to assure that the cylinders are serviced to meet safety standards and to assure that the quality of the gas supplied is not degraded by a government container. This standard is also applicable to cylinders that require reconditioning, repair, and rebuild to assure a level of renewal that meets the needs of the government and industry in gas handling. This standard is also to be a guide when cylinders are sorted, graded, and classified for storage, salvage, or disposal in depot facilities.【英文标准名称】:Rigidcellularplastics-Determinationofwatervapourtransmissionproperties

【摘要】:本标准规定了硬质泡沫塑料的水蒸气透过量、水蒸气透过率、水蒸气透过系数和水蒸气扩散阻力指数的测定方法。本标准适用于厚度为10mm以上的硬质泡沫塑料。可以是完整材料,也可以是白结层或粘附表层材料的泡沫材料。本标准规定三种不同的温度和湿度条件：a)38℃,湿度梯度为0％～88％；b)23℃,湿度梯度为0％～85％；c)23℃,湿度梯度为0％～50％。通过此方法获取的结果可用于产品设汁、生产控制以及产品规范。本方法适用于水蒸气透过量在3mg／(m’·s)～200mg／(m2·s)范围内的材料。
