EN 4503:2013 (E) 6 4 Health, safety and environment This standard does not necessarily include all health and safety requirements associated with its use. Persons using this standard shall be familiar with normal laboratory/test house practices. It is the responsibility of the user to establish satisfactory health and safety practices and to ensure conformity with any European, National or local laws/regulations. 5 Principle/Technique An aqueous extract is prepared using distilled water. The soluble chloride and sulphate are then measured by gravimetric method. A volumetric method may also be used to determine the amount of soluble chloride. 6 Resources 6.1 Apparatus/facilities 6.1.1 Round bottomed flasks of chemically resistant glass with a volume of 250 ml and a ground glass neck of size 24/29 in accordance with ISO 383 6.1.2 A glass stopper incorporating a stopcock with P.T.F.E. core liner to prevent sticking of the glass core in the neck of the stopcock NOTE Grease shall not be used for this purpose. 6.1.3 Water-cooled condensers 6.1.4 Laboratory balance, accurate to 0,000 2 g 6.1.5 Sinter glass crucibles, porosity 4 in accordance with ISO 4793 6.1.6 Titration vessel and reference half-cell, with suitable p
