1 Scope This International Standard specifies a method for the determination of trace amounts (> 0,001 mg/kg) of lead in all types of crude or refined edible oils and fats. 2 Principle The oil or fat is atomized in a graphite furnace, with or without a platform, connected to an atomic absorption spectrometer which has been previously calibrated using standard […]

1 Scope This European Standard specifies a calculation method to determine the energy balance value of glazing. This European Standard applies to transparent materials such as glass and combinations of glass used to glaze windows in buildings. This method is intended to evaluate the balance of heat loss and useful heat gain by solar radiation entering the building through the […]

1 Scope This European Standard specifies requirements for the content of welding procedure specifications for gas welding processes. This standard is part of a series of standards, details of this series are given in prEN ISO 15607, annex A. Variables listed in this standard are those influencing the quality of the welded joint. 2 Normative references This European Standard incorporates […]

1 Scope This standard is applicable to sprayed metal coatings for protection against corrosion at temperatures up to 1000°C (1273 K). www. bzfxw. com For the protection of iron and steel by sprayed aluminium and zinc coatings against atmospheric corrosion reference should be made to prEN ISO 2063. Coating materials other than metals, although they may be applied by spraying, […]

1 Scope This European Standard specifies a test method for determining the impact strength of the heels of ladies’ shoes. The result provides an assessment of the liability to failure under the occasional heavy blows received during wear. NOTE While the test method is applicable to all types of high heels, of whatever construction, it is particularly useful for injection-moulded […]
