3 Terms and definitions

The following terms and definitions apply to this document.

4 Principle

The rectangular specimen installed between the impact fixture fixing plate and the wooden frame is subjected to a certain energy impact at the specified test point along the thickness direction.

Use a flat-head probe to gently probe the impact area. If the needle tip penetrates the sample, the sample fails; otherwise, the sample does not fail.

5 Samples

5.1 The specimen is square with a side length of (460 ± 3) mm and a thickness of (0.25 ~ 2.00) mm.

5.2 Select 4 test points for each sample. The test point locations are shown in Figure 1.The tolerances not marked in Figure 1 are ±0.25 mm.
