ISO 13887:2004建立了表1所列七个等级的冷压下钢板的成形性和强度改进测试系统。它适用于板材表面至关重要的应用。 本国际标准不适用于指定为商业质量或拉伸质量的钢（见ISO 3574）、结构质量的钢（见ISO 4997）或高抗拉强度和低屈服点且具有改进成形性的钢（见ISO 14590）。

ISO 13887:2004 establishes a system of testing for improved formability and strength of cold-reduced steel sheet in the seven grades listed in Table 1. It is suitable for applications where the surface of the sheet is of prime importance. This International Standard is not applicable to steels designated as commercial quality or drawing qualities (see ISO 3574), steels of structural quality (see ISO 4997) or steels of high tensile strength and low yield point with improved formability (see ISO 14590).
