Thermal insulating products for building equipment and industrial installations. Determination of trace quantities of water soluble chloride, fluoride, silicate, sodium ions and pH Ingestion-build-266356 and leathers including multilayer assemblies1 Scope This standard specifies the equipment and procedures for determining trace quantities of the water soluble chloride, fluoride, silicate and sodium ions in an aqueous extract of the product. It also describes a procedure for the determination of the pH of the aqueous extract. The standard is applicable to thermal insulating products. NOTE The determination of these parameters may be relevant for thermal insulating products intended for
