Introduction ISO (Internasionale Organisasie vir Standardisasie) is 'n wêreldwye federasie van nasionale standaarde-liggame (ISO-lidliggame). Die ontwikkeling van internasionale standaarde word gewoonlik deur ISO tegniese komitees uitgevoer. Each member group interested in a subject on which a technical committee has been established has the right to be represented...
1 Range This STANDARD specifies the technical REQUIREMENTS AND test methods for electroplating of Tin-lead alloys with tin content ranging from 50% aan 70%(mass ratio) (see 10.3). This standard applies to electroplating of tin-lead alloys to prevent corrosion and improve soldering properties on electronic, electrical and other metal products. This standard also applies...
Meaning and Use 3.1 Since the pipe coating is subject to concentrated pressure exerted by the weight of the pipe and the backfill, this test is mainly used to determine the resistance of the coating to penetration or deformation under controlled conditions. 3.1.1 If the coating is not penetrated, the deformation of...
Betekenis en doel 4.1 The test will provide information about the ability of the coating applied to the pipe to resist cracking, peeling or other mechanical damage caused by bending. Since the test is applicable to commercially produced coated pipes, the results can be directly used to select similar service materials....
Omvang van 1.1 This test method includes an accelerated procedure for simultaneously determining the comparative characteristics of the insulating coating system applied to the exterior of the steel pipe with the purpose of preventing or mitigating corrosion that may occur in underground service where the pipe will come into contact with...
