Foreword

GB/T 33371 "paint and varnish-based alkyd resin" is divided into four parts.

--- Part 1. General test methods;

--- Part 2. Determination of phthalic anhydride content;

--- Part 3. Determination of unsaponifiable matter content;

--- Part 4. Determination of fatty acid content.

This section GB/T 33371 Part 1.

This section drafted in accordance with GB/T 1.1-2009 given rules.

1 Scope

GB/T 33371 provisions of this part of the paints, varnishes and similar products commonly used alkyd resin test methods.

This section applies to the determination of alkyd resins for varnishes, and similar products but also for alkyd resins made from alkyd resins that can be used as paints and Varnish-based paint with a variety of solutions and similar formulations.

Test methods for alkyd resins of a particular type shall be agreed upon by the parties involved.
