1 Scope This European standard specifies product safety labels for burning indoor candles. 2 Product safety labels 2.1 Safety information The messages specified in Table 1 represent the minimum safety information with which a candle can be labelled. This safety information shall be given on a product safety label in the form of a symbol (see Table 1, 1st column) […]

1 Scope This European Standard specifies a test method for the assessment of substitute tests performed with volatile test media for the determination of migration from paper and board intended to come into contact with fatty foodstuffs at all temperatures and for any period of time. NOTE At the time that this European Standard was prepared, the EU directives for […]

1 Scope This European Standard specifies a method for the determination of the elements cadmium and lead in animal feeding stuffs by graphite furnace atomic absorption spectrometry (GF-AAS) after pressure digestion. The method limit of quantification for each element is dependent on the sample matrix as well as the instrument. For cadmium a limit of quantification of 0,05 mg/kg should […]

1 Scope This European Standard specifies a method for the determination of nitrate and ammoniacal nitrogen with reduction according to Ulsch. The method is applicable to all nitrogenous fertilizers, including compound fertilizers, in which nitrogen is found exclusively in nitrate form, or in ammoniacal and nitrate form. 2 Normative references The following referenced documents are indispensable for the application of […]

1 Scope This European Standard specifies a method for the determination of nitric and ammoniacal nitrogen with reduction according to Arnd (modified for each of the variants a, b and c). The method is applicable to all nitrogenous fertilizers, including compound fertilizers, in which nitrogen is found exclusively in nitrate form, or in ammoniacal and nitrate form. 2 Normative references […]

1 Scope This European Standard specifies a method for the determination of the mass fraction of niacin in foodstuffs by high performance liquid chromatography (HPLC) by three different ways of hydrolysis, acid hydrolysis (A), enzymatic hydrolysis (B) or acid/alkaline hydrolysis (C). The method has been validated in interlaboratory tests on fortified and non-fortified samples such as breakfast cereal powder, chocolate […]

1 Scope The ammonia test is a quick test to check the chemical resistance of the internal protective coating of aluminium tubes. The test is used for flexible aluminium tubes for ammonia containing fillings and as an introductory test for newly developed internal protective coatings. 2 Test device / media – Aqueous solution of ammonia with a mass fraction of […]

1 Scope This European Standard defines the requirements and test methods applicable to factory applied internal polyurethane high duty corrosion protection of buried ductile iron pipes and fittings conforming to EN 545,EN 598 and EN 969 for use at permanent operating temperatures up to 45 °C. 2 Normative references The following referenced documents are indispensable for the application of this […]

1 Scope This European standard specifies a method for the direct determination of water in ethanol to be used in gasoline blends. It is applicable in the range 0,05 % (m/m) to 0,54 % (m/m). NOTE For the purposes of this European Standard, the term “% (m/m)” is used to represent the mass fraction. WARNING — Use of this standard […]

1 Scope This European Standard EN 15706 specifies test methods and requirements for the strength and durability of all types of slide fittings for all types of sliding doors and roll fronts sliding horizontally and vertically and their components for all fields of application. The tests consist of the application of loads, forces and velocities simulating normal functional use, as […]
