Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for standardization work Part 1: Structure and drafting rules for standardization documents" Drafting is required.

This document is equivalent to ISO 14631:2021 "Requirements and test methods for high-impact polystyrene (PS-I) extruded sheets".

1 Scope

This document specifies the requirements for high-impact polystyrene (PS-I) extruded sheets (hereinafter referred to as "PS-I") without fillers and reinforcements.

The corresponding test method is described.

This document applies to PS-I extruded sheets with a thickness range of 0.25 mm to 20.00 mm, including sheets extruded in coil form.
