This part of GB/T24328 specifies the test method for the mechanical penetration resistance (spherical bursting strength) of toilet paper and its products. Note: In general, two kinds of clamping devices can be used, and the inner diameters of the clamping rings are 50mm and 89mm respectively. This section should use a clamping device with an inner diameter of 50mm, consistent with GB/T 24328.9. The clamping device with an inner diameter of 89 mm can be equipped with a converter to convert the inner diameter to 50 mm. This section applies to toilet paper and its products.
