ISO 8977:2002规定了外径范围为5 mm至50 mm的无头和有头矩阵的基本尺寸和公差，单位为毫米。 它给出了材料和硬度的示例，并指定了符合本国际标准要求的基体的名称。 根据ISO 8977:2002对矩阵的尺寸和公差进行调整，以满足ISO 8020对冲头的要求。

ISO 8977:2002 lays down the basic dimensions and tolerances in millimetres for headless and headed matrixes, in the outside diameter range of 5 mm to 50 mm. It gives examples of material and hardness, and specifies a designation for matrixes that meet the requirements of this International Standard. Matrixes in accordance with ISO 8977:2002 are adapted in their dimensions and tolerances to meet the required for punches in accordance with ISO 8020.
