标准范围

本国际标准规定了一种试验方法，用“三点弯曲法”测定固化粘合剂（如有必要，使用底漆）粘附到具有特定表面光洁度或经过特定表面处理的基材上的能力。本标准仅适用于质量保证，且仅适用于刚性或抗弯曲能力足够的基材，如钢或铝合金。对于其他基材，根据弹性模量调整厚度或使用合适的加强筋。允许粘合剂在不施加压力的情况下固化，以获得提供足够刚度所需的厚度，否则用与基材相同材料和厚度的粘合加强件代替粘合剂块。本试验方法不适用于薄膜粘合剂。

This International Standard specifies a test method to determine the ability of a cured adhesive (if necessary with a primer) to adhere to a substrate with a certain surface finish, or which has been subjected to a specific surface preparation, using the "three-point bending method".This standard is only applicable to quality assurance and only to substrates which are rigid or resistant enough to bending, such as steel or aluminium alloys. For other substrates, the thickness is adjusted to the modulus of elasticity or a suitable stiffener is used.The adhesive is allowed to cure without the application of pressure in order to obtain the thickness needed to provide sufficient rigidity, otherwise a bonded reinforcing piece of the same material and the same thickness as the substrate is substituted for the block of adhesive.This test method is not suitable for film adhesives.
