Test Items		TAT (Working Days)
HB		7
12 pieces with the size of 125 ±5 mm long by 13.0 ±0.5 mm wide, and provided in the minimum thickness and 3.0 (-0.0 +0.2) mm thick. The 3.0 mm thick specimens are not necessary if the minimum thickness is greater than 3.0 mm, or the maximum thickness is less than 3.0 mm. The maximum thickness is not to exceed 13 mm. The maximum width is not to exceed 13.5 mm, the edges are to be smooth, and the radius on the corners is not to exceed 1.3 mm.
12 pieces with the size of (125 ± 5) × (13 ± 0,2) mm X thickness(需要提供测试的Zui小厚度样品和3毫米厚度样品,若样品Zui小厚度大于3mm,或者Zui大厚度小于3MM,则可以不用提供3mm样品;样品Zui大厚度不超过13mm,Zui大宽度不超过13.5mm,)
V0, V1, V2		14
17 pieces with the size of 125 ±5 mm long by 13.0 ±0.5 mm wide, and provided in the minimum and maximum thicknesses. The maximum thickness is not to exceed 13 mm. Specimens in intermediate thicknesses are also to be provided and shall be tested if the results obtained on the minimum or maximum thickness indicate inconsistent test results. Intermediate thicknesses are not to exceed increments of 3.2 mm. Also, the edges are to be smooth, and the radius on the corners is not to exceed 1.3 mm.
17 pieces with the size of (125 ± 5) × (13 ± 0,2) mmX thickness(需要提供测试的Zui小厚度样品和Zui大样品厚度；样品Zui大厚度不超过13mm，如果Zui小厚度样品和Zui大厚度样品得出的结果不一致，则还需要提供中间尺寸样品，中间尺寸厚度跨度不超3.2mm)

17 pieces 150 ±5 mm long by 50 ±1 mm wide, in the minimum and maximum thicknesses covering the thickness range to be considered. Specimens tested by this method are limited to a maximum thickness of 13 mm. Specimens in intermediate thicknesses are also to be provided and shall be tested if the results obtained on the minimum and/or maximum thickness indicate inconsistent test results. Intermediate thicknesses are not to exceed increments of 6 mm. The maximum width is not to exceed 50 mm. The edges are to be smooth and the radius on the corners is not to exceed 2 mm
