1 Scope

GB/T 25835-2010 is the Chinese national standard on epoxy-coated steel wires for cables, in the field of metallurgy. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 23 December 2010 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 September 2011. Classification: ICS 77.140.65, CCS H49. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the terms and definitions with epoxy coated steel wire rope, product marking, ordering the content, materials, coating, technical requirements, coating Repair, test methods, inspection rules, packaging, marking and quality certification. This standard applies to bridges, buildings, and other areas of geotechnical anchoring higher corrosion requirements of the cable structure.
