【英文标准名称】: Standard Test Method for Specific Cathodic Disbonding of Pipeline Coatings 【原文标准名称】: 管道涂层特效阴极剥落的标准试验方法 【标准号】: ASTM G80-2007 【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】: D01.48【标准类型】: (Test Method)【标准水平】: ()【中文主题词】: 胶粘连接件;粘结强度;涂层;材料;非金属;持久性;管道;测试【英文主题词】: anode; cathodic; disbondment; electrical stress; electrolyte; equivalent diameter【摘要】: 1.1 This test method covers an accelerated procedure for simultaneously determining comparative characteristics of insulating coating systems applied to steel pipe exterior for the purpose of preventing or mitigating corrosion that may occur in underground service where the pipe will be in contact with natural soils and may or may not receive cathodic protection. It is intended for use with samples of coated pipe taken from commercial production and is applicable to such samples when the coating is characterized by function as an electrical barrier.1.2 This test method is specific with no options. For alternative methods of test see Test Methods G 8.1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only..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】: A29【国际标准分类号】: 23_040_99【页数】: 5P.;A4【正文语种】:
