This European Standard specifies the composition, property requirements including electrical properties, and tolerances on dimensions and form for copper rod, bar and wire for general electrical purposes. Cross sections and size ranges are: - round, square and hexagonal rod with diameters or widths across flats from 2 mm up to and including 160 mm; - bar with thicknesses from 2 mm up to and including 40 mm and widths from 3 mm up to and including 250 mm; - round, square, hexagonal and rectangular wire with diameters or widths across flats from 2 mm up to and including 25 mm, as well as thicknesses from 0,5 mm up to and including 12 mm with widths from 1 mm up to and including 250 mm. The sampling procedures and test methods for verification of conformity to the requirements of this standard are also specified. NOTE Drawn, round copper wire - plain or tinned, single or multiline - for the manufacture of electrical conductors is specified in EN 13602.

This European Standard specifies methods for assessing the tin coating on drawn round copper wire for the manufacture of electrical conductors, e.g. according to EN 13602. This European Standard includes test methods for the determination of the following characteristics: a) thickness of the unalloyed tin coating; b) continuity of the tin coating; c) adherence of the tin coating. WARNING - This European Standard can involve the use of hazardous materials, operations, and equipment. This standard does not purport to address all of the safety problems associated with their use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

This European Standard specifies the composition, property requirements including electrical properties, and tolerances on dimensions and form for copper profiles and profiled wire for electrical purposes, which would fit within a circumscribing circle of maximum 180 mm diameter. The sampling procedures, the test methods for verification of conformity to the requirements of this standard, and the delivery conditions are also specified.

This document applies to high pressure die casting machines: a) hot-chamber die casting machines (horizontal or vertical die closing system), and b) horizontal/vertical cold-chamber die casting machines (horizontal or a vertical die closing system). It applies to high pressure die casting units, i.e., high pressure die casting machines (HPDCM) and their interfaces with the following ancillary equipment: c) die, d) melting, holding and dosing furnaces (see ISO 13577-1), e) metal feeding equipment, f) inserting and removal devices, g) spraying appliances, h) heat exchanger for the die. This ancillary equipment itself is not covered. Additional risks arising from the material being cast are not covered. This standard does not apply to low pressure die casting machines and/or gravity die casting machines. This standard deal with all significant hazards, hazardous situations and events relevant to pressure die casting machines when used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4). It provides the requirements to be met by the manufacturer to ensure the safety of persons and property during transport, commissioning, use, de-commissioning and maintenance periods, as well as in the event of foreseeable failures or malfunctions that can occur in the equipment
