ISO 14270:2016标准是一项关于抗焊接的破坏性测试的标准，主要用于机械剥离测试电阻点焊、电阻焊接、焊缝和凸起焊接的试样尺寸和程序。该标准适用于所有类型的电阻焊接，包括手动和自动焊接。

该标准规定了机械剥离测试的试样尺寸和程序，以确保测试结果的准确性和可重复性。试样的尺寸和形状应符合标准规定，并且应在测试前进行清洁和表面处理。测试时，试样应放置在夹具中，并在一定的速度下进行剥离，以测量焊接的强度和可靠性。

该标准还规定了测试结果的评估方法，包括焊接强度、剥离模式和剥离位置等。测试结果应记录并报告，以便进行后续分析和改进。

总之，ISO 14270:2016标准是一项重要的抗焊接破坏性测试标准，可以帮助焊接行业提高焊接质量和可靠性，减少焊接缺陷和故障。
