DIN EN ISO 6520-1-2007 焊接及相关工艺.金属材料几何缺陷分类.第1部分:氧炔焊
Welding and allied processes - Classification of geometric imperfections in metallic materials - Part 1: Fusion welding (ISO 6520-1:2007); Trilingual version EN ISO 6520-1:2007
This part of ISO 6520 will serve as the
basis for a precise classification and
description of weld imperfections.
In order to avoid any confusion, the
types of imperfection are defined with
explanations and illustrations where
necessary.
Metallurgical imperfections are not
included.
Another system for the designation of
imperfections is possible, according to
ISO/TS 17845. AnnexB gives the
correspondence between the existing
classification of imperfections
according to ISO 6520-1 and the
designation system according to
ISO/TS 17845.
NOTE In addition to terms and
definitions used in two of the three official
ISO languages (English and French), this
part of ISO 6520 gives the equivalent terms
and definitions in the German language;
these are published under the responsibility
of the member body for Germany (DIN).
However, only the terms and definitions
given in the official languages can be
considered as ISO terms and definitions.
