GB/T 9015-2025Hexamethylenetetramine for industrial use (English PDF)

Foreword

This document complies with the provisions of GB/T 1.1-2020 "Standardization Work Guidelines Part

1.Structure and Drafting Rules of Standardization Documents". Drafting. This document replaces GB/T 9015-1998 "Industrial Hexamethylenetetramine". Compared with GB/T 9015-1998, the main differences are structural adjustments and revisions. Aside from the logical changes, the main technical changes are as follows:

a) Change the product grading system to a classification system (see Chapter 4, Chapter 3 of the.1998 edition);

b) The indicators for appearance, purity, moisture, and residue on ignition have been changed (see Table 1,.1998 edition);

c) The method for determining moisture content without pyridine Karl Fischer reagent has been removed, and the method for determining moisture content by drying has been added (see 6.4.2,.1998). Version 4.2.2);

d) The sample weight and ignition temperature for the determination of residue on ignition have been changed (see 6.5,

4.3 of the.1998 edition);

e) The methods for determining heavy metals, chlorides, sulfates, and ammonium salts have been revised (see 6.6-6.9, 4.5-

4.8 of the.1998 edition);

f) The inspection rules have been changed (see Chapter 7, Chapter 5 of the.1998 edition);

g) Changes were made to the markings, packaging, transport, and storage (see Chapter 8, Chapter 6 of the.1998 edition). Please note that some content in this document may involve patents.

1 Scope

GB/T 9015-2025 is the Chinese national standard covering hexamine as sold - the assay and the ash, the moisture and the chloride and sulfate, the appearance, and the packaging of a solid used as a resin hardener, a rubber accelerator and a fuel tablet. It replaces GB/T 9015-1998, a standard twenty-seven years old. In force from 1 May 2026. Issued on 31 October 2025, it has been in force since 1 May 2026, replacing GB/T 9015-1998.

This document provides the product classification for industrial hexamethylenetetramine, and specifies the technical requirements, inspection rules, marking, packaging, transportation, and storage. The document describes the corresponding experimental methods. This document applies to industrial hexamethylenetetramine produced from ammonia and formaldehyde.

Note. Hexamethylenetetramine molecular formula. C6H12N4, structural formula., relative molecular mass. 140.19 (based on the 2022 international relative atomic mass).
