1.1 本试验方法确定了薄膜开关或带有导电电路的印刷电子设备任何部分的弯曲方法。 1.1.1 以国际单位制给出的数值应视为标准。括号中给出的值仅供参考。 1.2 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 ====意义和用途====== 3.1 薄膜开关、印刷电子设备或其部件的弯曲会影响其视觉外观、机械完整性或电气功能。 本试验方法模拟了制造、安装或使用过程中可能出现的条件。 3.2 弯曲测试可能具有破坏性，因此任何测试的样品都应被视为不适合未来使用。 3.3 测试的具体领域包括但不限于: 3.3.1 薄膜开关柔性尾翼或印刷电子设备，以及 3.3.2 薄膜开关或印刷电子设备的任何可能受到弯曲的部件。

1.1 This test method establishes a method for the bending of any part of a membrane switch or printed electronic device with conductive circuits. 1.1.1 The values given in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. ====== Significance And Use ====== 3.1 Bending of membrane switches, printed electronic device or their components can affect their visual appearance, mechanical integrity or electrical functionality. This test method simulates conditions that may be seen during manufacture, installation or use. 3.2 Bend testing may be destructive, therefore any samples tested should be considered unfit for future use. 3.3 Specific areas of testing include, but are not limited to: 3.3.1 Membrane switch flex tails or printed electronic device, and 3.3.2 Any component of a membrane switch or printed electronic device that may be subjected to bending.
