求助: ISO 13802 这句话该怎么理解?

试验机/硬度计

  • 哪位有ISO 13802电子版? 麻烦发个邮件。谢谢!

    The test machines covered by this international standard are of pendulum type. The impact energy W absorbed in impacting a test specimen is taken as being equal to the difference between the potentail energy E of the pendulum and the energy remaining in the pendulum after impacting the specimen. The impact energy is corrected for friction and air-resistance losses.

    各位请帮忙理解这段话!谢谢!

    标准中有这么一句话:

    应是ISO-13302标准,不是13802

    偶没有中文标准,以下是本人的理解:

    本国际标准适用于摆锤式试验机,可以认为,试样冲击过程中吸收的冲击功W等于摆锤的初始势能E与冲击后摆锤的残余势能之差,冲击功根据摩擦和空气阻力影响作修正。

    谢谢, 楼上的!
    现在明白了,只有difference一词阻碍了我的理解。

    偶也是推测的
    应该是这个意思吧

    本标准只涉及摆锤式试验机。在冲击试样过程中所吸收的冲击能量W等于摆锤的势能E与冲击试样后摆锤的剩余能量之差。考虑摩擦和空气阻力的损失,对冲击能量进行修正
