1 Scope

GB/T 14686-2008 is the Chinese national standard on asphalt glass felt used in waterproofing, in the field of construction materials and building. 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 30 June 2008 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 April 2009. Classification: ICS 91.120.30, CCS Q17. 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 glass fiber asphalt waterproofing membrane (referred to as asphalt fiberglass fetal membrane) classification and marking requirements, test side Method, inspection rules, marking, packaging, transportation and storage. This standard applies to glass fiber mat base for the child, dipping asphalt, both sides covered with insulating material made of a waterproof membrane.
