                   【英文标准名称】:     Standard Practice for Safeguarding Against Embrittlement of Hot-Dip Galvanized Structural Steel Products and Procedure for Detecting Embrittlement            【原文标准名称】:     热浸镀锌结构钢产品的脆性防护和脆性检测程序的标准规程            【标准号】:     ASTM A143/A143M-2007            【标准状态】:     现行            【国别】:                 【发布日期】:     2007    【实施或试行日期】: 【发布单位】: 美国材料与试验协会(US-ASTM)【起草单位】: A05.13【标准类型】: (Practice)【标准水平】: ()【中文主题词】: 镀锌涂层;电镀层;金属涂层钢制品;锌涂层钢制品【英文主题词】: coatings-zinc;  galvanized coatings;  steel products-metallic coated;  zinc coatings-steel products【摘要】: 1.1 This practice covers procedures that can be followed to safeguard against the possible embrittlement of steel hot-dip galvanized after fabrication, and outlines test procedures for detecting embrittlement. Conditions of fabrication may induce a susceptibility to embrittlement in certain steels that can be accelerated by galvanizing. Embrittlement is not a common occurrence, however, and this discussion does not imply that galvanizing increases embrittlement where good fabricating and galvanizing procedures are employed. Where history has shown that for specific steels, processes and galvanizing procedures have been satisfactory, this history will serve as an indication that no embrittlement problem is to be expected for those steels, processes, and galvanizing procedures.1.2 This practice is applicable in either inch-pounds or SI units. Inch-pounds and SI units are not necessarily exact equivalents. Within the text of this practice and where appropriate, SI units are shown in brackets.This standard does not purport to address all of the safety concerns, if any, associated with its 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.【中国标准分类号】: H22【国际标准分类号】: 77_140_10【页数】: 3P.;A4【正文语种】:
