BS EN ISO 2818:2019规定了从模压和注塑塑料、挤出板材、板材以及部分成品或全部成品加工和开槽试样时应遵循的一般原则和程序。为了建立可重复加工和开槽条件的基础，采用以下通用标准化条件。然而，我们假设所使用的确切程序是由相关材料规范或特定试验方法的标准选择或规定的。如果没有规定足够详细的程序，相关方同意使用的条件。 交叉引用:ISO 2557-2ISO 291ISO 6104ISO 3855ISO 6106ISO 20753ISO 294（所有部分）ISO 468ISO 3002-1ISO 2557-1ISO 21950ISO 293ISO 295购买本文件时提供的所有当前修订版均包含在购买本文件中。

BS EN ISO 2818:2019 establishes the general principles and procedures to be followed when machining and notching test specimens from compression-moulded and injection-moulded plastics, extruded sheets, plates and partially finished or wholly finished products.In order to establish a basis for reproducible machining and notching conditions, the following general standardized conditions are applied. It is assumed, however, that the exact procedures used are selected or specified by the relevant material specification or by the standards on the particular test methods. If sufficiently detailed procedures are not thus specified, the interested parties agree upon the conditions to be used.Cross References:ISO 2557-2ISO 291ISO 6104ISO 3855ISO 6106ISO 20753ISO 294 (all parts)ISO 468ISO 3002-1ISO 2557-1ISO 21950ISO 293ISO 295All current amendments available at time of purchase are included with the purchase of this document.
