1 Scope This European Standard specifies requirements for the design, manufacture and testing of closed expansion vessels with built in diaphragm, which will hereinafter be called “vessels”, and a) whose diaphragm serves to separate water on the one hand and air / nitrogen on the other hand in heating/cooling systems or fresh water systems; b) which are manufactured singly or […]

5.2 Dimensional measurements 5.2.1 Width 5.2.1.1 Principle The distance between the extremities of the shorter linear dimension of the panel facing shall be measured. 5.2.1.2 Apparatus A metal rule or a metal tape permitting readings to 1 mm. 5.2.1.3 Procedure Take two measurements to the nearest 1 mm on each facing of each panel (see Figure 3 a)). 5.2.1.4 Expression […]

1 Scope This European Standard is applicable to the determination of aflatoxins B 1 , B 2 , G 1 and G 2 in hazelnuts, figs, pistachios, peanuts and paprika powder. The limit of quantification of the method is 0,8 ng/g for each aflatoxin or better (value derived from in-house and collaborative study), depending on the equipment used. 2 Normative […]

1 Scope This European Standard specifies a test method for the determination of water absorption in reinforced bitumen sheets which could influence the functional behaviour of these sheets. NOTE It is primarily the reinforcement’s ability to absorb water which is examined by this test. 2 Normative references The following referenced documents are indispensable for the application of this European Standard. […]

1 Scope This European Standard specifies a test method to evaluate the reaction to fire performance of building products. A fire is simulated which under well-ventilated conditions starts in a corner of a small room with asingle open doorway. The method is intended to evaluate the contribution of a surface product to fire growth in a room configuration,using a specified […]

1 Scope This European Standard specifies requirements for coloured or uncoloured anodic oxidation coatings on wrought and cast products in aluminium and aluminium alloys for use in contact with food. These requirements cover the chemical composition of the bath, the sealing and the properties of the obtained anodic oxidation coatings. They do not cover dyestuffs and pigments but do cover […]

1 Scope This standard describes two methods for the determination of the total (free and bound) acid soluble chloride content of hardened concrete or mortar. This information is intended for use in estimating the risk of chlorideinduced corrosion of the steel reinforcement. It may be used on samples of powder obtained either by drilling or from cores or fragments removed […]

1 Scope This European Standard specifes a method for the determination of tetraacetyl ethylene diamine (TAED) content greater than or equal to 25 g/100 g in granules. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references,only the edition cited applies. For undated references, the latest edition of the referenced document (including […]

1 Scope This European Standard specifies a method for the determination of the content of low boiling solvents, e.g. ethanol, ethanol propan-1-ol and propan-2-ol in liquid detergents. Typically only one solvent is present in these kinds of samples. The method is applicable to liquid detergents containing low boiling solvents in the range from 0,5 % to 10 % by weight. […]

1 Scope This European Standard specifies requirements for cords and drawstrings on children’s clothing, including disguise costumes and skiwear, up to the age of 14 years. Within the scope of this European Standard it is not possible to cover all potential hazards that may create an unsafe garment. Conversely, identifiable specific hazards in certain styles/design of garment might not present […]
