本国际标准规定了在一定温度下测定实验室板材抗拉强度的程序 测试范围最初为零。适用于各种纤维，包括再生纤维。化验单 可以在干燥、重写或从未干燥的情况下进行测试。

This International Standard specifies the procedure for determining the tensile strength of laboratory sheets at a test span which is initially zero. It is applicable to all kinds of fibres, including recycled fibres. The laboratory sheets can be tested either dry, rewetted, or never dried.
