1 Scope

GB/T 13217.7-2023 is the Chinese national standard on test method for adhesion to substrate of ink with tape, in the field of paint and colour industries. 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 6 August 2023 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 March 2024. Classification: ICS 87.080, CCS Y44. 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 document specifies the test method for ink adhesion. This document is applicable to the adhesion determination of various types of inks used on plastic films, aluminum foil, tinplate, paper and other substrates. glue The adhesion of printing ink, gravure ink black, flexo printing ink, screen ink, inkjet printing ink and other inks is measured by disc peeling method and manual peeling. The adhesion of iron printing ink is determined by the circle method or the crosshatch method.
