大家是怎么理解EN71-3-2013+A1-2014中7.3.3.3部分纸张的尺寸?

气质联用(GCMS)

  • EN71-3-2013+A1-2014标准中7.3.3.3部分,“Each test piece shall have at least one dimension of approximately 6 mm when possible”这句话,是解释为尽可能接近于6mm,还是最大不能超过6mm。大家是怎么理解的。

    贴多点内容上来,究竟是说样品大小,还是指定了纸张样品大小?

    7.3.3.3 Paper and paper board
    If possible obtain a test portion of not less than 100 mg of the paper or paper board. Each test piece shall have at least one dimension of approximately 6 mm when possible (see H.6). The use of pre-prepared reference materials for visual size comparison is recommended.
    纸张样品应该裁剪到哪个尺寸?

    H.6 Size of test pieces (7.3.3.2, 7.3.3.3, 7.3.3.4) The test pieces should have at least one dimension of approximately 6 mm, but preferable two dimensions. As an example, a paper sheet shall be cut in pieces of approximately 6 by 6 mm. A fish line shall be cut in pieces of approximately 6 mm in length. It shall be practical for the laboratory to prepare these pieces. The aim is to achieve comparable surface areas between laboratories.
    这个是H.6的内容

    按我理解,纸张样品要剪成小片,,尺寸尽量保持在6mmx6mm左右

    剪成6mm*6mm,可以比这个尺寸小,但不能超过这个尺寸。

    若剪成3mm*3mm或更小,符合标准吗?

    上一次实验室评审,因为这个问题给开了一个NC。
