71.080.20 - Halogenated hydrocarbons

This Technical Specification describes the determination of perfluorooctanesulfonate (PFOS) in concentrated extracts from coated and impregnated solid articles, liquids and fire extinguishing foams using high performance liquid chromatography-tandem mass spectrometry (LC-tandemMS) or quadrupole mass spectrometry (LC-qMS). The method is applicable for a concentration range for PFOS in the extract solution of 0,5 μg/l to 50 μg/l.

This document specifies the method for the determination of yield strength increase by the effect of heat treatment (Bake-Hardening-Index) for steel.
NOTE   This test is applied in particular, to steels showing a mechanism of bake hardening, which are specially intended for automotive industry.

Specifies a method, the principle of which is based on evaporation of a test portion under specified conditions, using special apparatus, and weighing of the residue after evaporation. Details the procedure and provides information on the expression of results and the data to be included in the test report.

Applicable to products the acidity of which is between 2 mol and 200 mol of univalent acid per kg. Two procedures are given: one is applicable to liquid products (R11, R113, etc.) and the other one to gaseous (R12, R22, etc.). The principle consists in extraction of the acids by water. Titration of the acids in the aqueous phase with standard volumetric sodium hydroxide solution in the presence of bromocresol green as indicator. A figure shows an apparatus for absorption of acids for products wh...view more

Applicable for sampling from containers (cylinders, drums, tanks, etc.). Sampling of the product in a steel cylinder, previously cleaned, dried and evacuated. The stainless steel cylinder shall be capable of withstanding an internal pressure of at least 3 MPa (30 bar). The cylinder is filled to the filling ratio allowed by the safety considerations. Details are given in the relevant international standards for the products considered. The samples shall be taken only from the liquefied phase. A d...view more

These methods are applicable to products not contaminated by an axtraneous phase (for example, water). Accidental pollution is also considered. Three cases are considered: small containers, large containers and continuous sampling. The procedure consists in formation of a blended bulk sample, representing the whole of the batch, by mixing several samples. The number and the method of taking of the elementary samples will depend on the number and capacity of containers.
