HG/T 6500-2026Determination of phenolic hydroxyl groups in epoxy resin - Spectrophotometric method (English PDF)

HG/T 6500-2026 is the English-translated version of 环氧树脂中酚羟基的测定 分光光度法.

HG/T 6500-2026 describes a spectrophotometric method for the determination of phenolic hydroxyl groups in epoxy resin. It is a test method standard: it concerns how the phenolic hydroxyl content of an epoxy resin is measured by spectrophotometry, so that different laboratories working on the same material follow the same approach. The English translation reproduces the full Chinese text of the method.

The standard is useful to epoxy resin producers who check their product, to quality control and independent test laboratories, and to resin buyers who need comparable analytical results. It carries the /T suffix and is therefore a voluntary industry standard. The Ministry of Industry and Information Technology approved it on 15 July 2026, and it comes into effect on 1 February 2027. It is a new method and does not replace an earlier edition.
