2、rd applies to commercial steel wires, the surface condition of which results from the manufacturing rocesses normally used in wire refinement, and which are manufactured in large quantities. his Standard does not apply to steel wires, the surface condition of which is obtained by special processes.
3、Such ires include steel wires with coatings applied by galvanic (electrolytic) nickel plating, chrome plating, cadmium lating etc., or by enamelling, or steel wires with metallic coatings already applied which are subsequently treated iemically. Such steel wires are not considered to be commercial.
4、Purpose he object of this Standard is to lay down uniform denominations and abbreviations thereof for the surface condition f drawn steel wire; the manufacturing technique concerned forms the basis of these denominations. The denominations, r if necessary their abbreviations (e.g. for space-saving r
5、easons) according to this Standard are intended for use when mpiling designations, in particular when specifying standardized steel wires for the compilation of designations in tandards.

Page4 DIN 1653 Explanations The Standard DIN 1653 is intended to regularize the surface denominations
31、of commercial steel wires and the abbreviations thereof in accordance with the present day manufacturing techniques, in order to arrive at a uniform system of designations out of the multiplicity of designations previously used by producers and users, and to avoid misunderstandings and as a result w
32、rong deliveries. The specification of the manufacturing procedure which results in a given surface condition is only intended as a guideline. Identical or similar surfaces, e.g. resulting from annealing and hardening and tempering processes, have been listed separately, because differences can be as
33、certained on closer inspection, and because the manufacturing procedure is usually quite different basically. Wires which are produced in large quantities by the wire refining works, including e.g. ground and polished valve spring wires, have been classified as commercial, whereas wires produced onl
34、y occasionally in accordance with special methods, such as nickel plated, cadmium plated, chrome plated, copper and aluminium plated or enamelled wires, are not considered as being commercial. The abbreviations have as a general rule been formulated in such a way that they incorporate the first lett
35、er of the corresponding denominations; exceptions to this rule have only been made in cases where existing abbreviations were already featured in other standards on allied sub- jects, and where it was of course logical to adopt the same abbreviations if possible. It was also impossible to avoid some
36、 of the abbreviations adopted from coinciding with symbols or abbreviations relating to different subjects; this is because the number of letters and letter combina- tions available is relatively limited. No qualitative or quantitative statements have been made; such statements are appropriate in test standards resp. quality standards, e.g. the composition and thickness of metallic or non-metallic coatings etc. The object of the abbreviations is to save space or to simplify the designation on drawings, parts lists and orders, or to compile designations for standardized steel wires.
