ASTM G55-88(1998) 评定管道涂层修补材料的标准试验方法

1.1 This test method provides an accelerated means of determining the relative sealing abilities of pipeline patching materials that are used to seal holidays in pipeline coatings on steel pipe. This test method is intended for utilization of specimens of pipeline coatings on small-diameter pipe, for representing coatings used for buried or submerged service, and where the purpose of the coating is to provide an electrical barrier between the steel pipe and its environment. 1.2 This test method is not intended for evaluating patch materials that are overlapped upon themselves. 1.3 The values stated in SI units are to be regarded as the standard. 1.4 This standard does not purport to address all of the safety problems, 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.

ASTM G62-87(1998)e1 假期检测管道覆层的测试方法

1.1 These test methods cover the apparatus and procedure for detecting holidays in pipeline type coatings. 1.2 Method A is designed to detect holidays such as pinholes and voids in thin-film coatings from 0.0254 to 0.254 mm (1 to 10 mils) in thickness using ordinary tap water and an applied voltage of less than 100 V d-c. It is effective on films up to 0.508 mm (20 mils) thickness if a wetting agent is used with the water. It should be noted, however, that this method will not detect thin spots in the coating, even those as thin as 0.635 mm (0.025 mils). This may be considered to be a nondestructive test because of the relatively low voltage. 1.3 Method B is designed to detect holidays such as pinholes and voids in pipeline coatings; but because of the higher applied voltages, it can also be used to detect thin spots in the coating. This method can be used on any thickness of pipeline coating and utilizes applied voltages between 900 and 20 000 V d-c. This method is considered destructive because the high voltages involved generally destroy the coating at thin spots. 1.4 The values stated in SI units to three significant decimals are to be regarded as the standard. 1.5 This standard does not purport to address all of the safety problems, 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.

Standard Test Methods for Holiday Detection in Pipeline Coatings

ASTM G95-87(1998)e1 管道涂层阴极剥离试验的标准试验方法（附着电池法）

1.1 This test method covers accelerated procedures for simultaneously determining comparative characteristics of coating systems applied to steep 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 will receive cathodic protection. They are intended for use with samples of coated pipe taken from commercial production and are applicable to such samples when the coating is characterized by function as an electrical barrier. 1.2 This test method is intended to facilitate testing of coatings where the test cell is cemented to the surface of the coated pipe specimen. This is appropriate when it is impractical to submerge or immerse the test specimen as required by Test Methods G8, G42, or G80. Coating sample configuration such as flat plate and small diameter pipe may be used, provided that the test procedure remains unchanged. 1.3 This test method allows options that must be identified in the report. 1.4 This standard does not purport to address all of the safety problems, 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.

ISO 6704:1982 自动蒸气疏水阀 分类

Establishes a simple classification of the main types according to the mode of actuation of their obturation device and disregarding their details of conception and construction. Three categories of steam traps can be distinguished: mechanical traps, actuated by the level of condensate; thermostatic traps, actuated by the temperature of the condensate; thermodynamic traps, actuated by fluid dynamics.
