中文名称：建筑设备和工业装置用绝热产品 水溶性氯化物、氟化物、硅酸盐、钠离子的痕量和pH的测定
英文名称：Thermal insulating products for building equipment and industrial installations — Determination of trace quantities of water soluble chloride, fluoride, silicate, sodium ions and pH
发布日期：2011-01
标准范围
This International Standard specifies the equipment and procedures for determining trace quantities of thewater soluble chloride, fluoride, silicate and sodium ions in an aqueous extract of the product. It also describesa procedure for the determination of the pH of the aqueous extract. This International Standard is applicable tothermal insulating products.NOTE The determination of these parameters may be relevant for thermal insulating products intended forapplication to stainless austenitic steel surfaces. The presence of chloride, fluoride, silicate and sodium ions under certainconditions can influence the risk of stress corrosion cracking. See Annex B for further information.
