Introduction ISO (Organizația Internațională pentru Standardizare) este o federație globală a organismelor naționale de standardizare (organismele membre ISO). Elaborarea standardelor internaționale se realizează de obicei prin intermediul comitetelor tehnice ISO. 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% la 70%(raportul de masă) (vedea 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...
Semnificație și scop 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....
