This document specifies a European designation system of wrought aluminium and aluminium alloys, based on an international designation system, and the procedure to obtain such international designation.
It is in accordance with the "Recommendation" dated December 15, 1970, as revised in March 2002, for an International Designation System for Wrought Aluminum and Wrought Aluminum Alloys issued by the Aluminum Association, Washington DC 20006, USA.
This standard applies to wrought products and to ingots intended to be wrought.

This European Standard specifies material, design, inspection, testing and marking requirements of pressure equipment (e.g. vessels, pipes, valves) made from borosilicate glass 3.3 with a coefficient of mean linear thermal expansion of (3,3 +/- 0,1) x 10-6 K-1. The following are excluded: - circular, flat and tubular sight glasses, - equipment made from borosilicate glass with another coefficient of thermal expansion.

This European Standard specifies the quality requirements for apparatus, components, appliances and accessories of vitreous glass lined steel (including semi-crystallized enamel coatings) and steel cast used for process plants. It specifies the quality requirements and the tests to be carried out by the manufacturer as well as the necessary actions for repairing defects.
This European Standard is also applicable to glass lined pumps, pump components and fittings.
This European standard is not applicable to glass-lined flanged steel pipes and flanged steel fittings.
NOTE 1   Provisions for glass-lined flanged steel pipes and flanged steel fittings are given in DIN 2876 [1].
The test methods specified cover checking the enamel, dimensional accuracy and performance of apparatus and components.
This European Standard applies to new apparatus and components as well as used ones that have to be re-enamelled.
This European Standard does not contain requirements regarding the chemical and physical properties of vitreous and porcelain enamels.
NOTE 2   Examples of test reports are given in Annex A.

This European Standard specifies requirements on thermal shock resistance as well as heating and cooling procedures of standardised glass-lined apparatus, components, accessories, and glass-lined pipes primarily used for process equipment in chemical plants.
It specifies the limits of thermal shock resistance using diagrams (see Figure 1 and Figure 2). For
glass-lined steel, a difference is made between a thermal shock on the glass-lined side (by charging an apparatus) versus a thermal shock on the steel side (by heating and cooling an apparatus).
This European Standard applies to operating temperatures from - 25 °C to + 230 °C.
This European Standard is only applicable to enamelled unalloyed and low-alloy carbon steels.

This European Standard specifies requirements for the resistance to chemical attack and thermal shock of chemical enamels and their designation for ordering purposes.
It is applicable to enamelled apparatus, components and piping components primarily used for process equipment in chemical plants.
This European Standard only applies to unalloyed and low-alloy carbon steels suitable for enamelling.
NOTE   The main criteria for assessing enamel quality are the resistance to chemical attack and thermal shock and the structure of the cover coat enamel.
