Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. This standard replaces GB/T 8809-1988 "plastic film anti-pendulum impact test method." This standard and GB/T 8809-1988 compared to the main changes are as follows. --- This standard uses two types of punch; Key indicators --- hedge head size and so do the regulations; --- Instrument structure has been described. The standard proposed by China National Light Industry Council. This standard by the National Plastics Standardization Technical Committee (SAC/TC48) centralized. This standard was drafted. Beijing Light Industry Plastics Processing Institute of Applied Technology and Business University, Labthink Technology Co., Ltd. The main drafters of this standard. Wangxiu Xian, Wang Yuanming, Li Tian Hua, Bai Yu, Liu Si wide. This standard superseded standard previously issued as follows. --- GB/T 8809-1988. Plastic film anti-pendulum impact test

2 Normative references

The following documents for the application of this document is essential. For dated references, only the dated version suitable for use herein Member. For undated references, the latest edition (including any amendments) applies to this document. GB/T 2918-1998 plastic sample conditioning and testing of the standard environment GB/T 6672 plastic film and sheet thickness measurement of the mechanical measurements Principle 3 The sample is fixed to the specimen holder, allowing the film Charpy impact test machine punch at a certain speed and impact through the plastic film, Measuring the energy consumed by the punch. Plastic film in order to evaluate the energy pendulum impact resistance properties.

4 Sample

4.1 Samples for testing should be uniform thickness, smooth, defect-free, and has a representative. NOTE. Although this method the test object is a thin film (thickness no greater than 0.25mm sheet), but in the pendulum ensure that no damage and the punch of the premise, can be appropriately Increasing the thickness of the sample. 4.2 Preparation of the entire sample of at least 10 samples, the sample may be a circular diameter of 100mm or 100mm × 100mm Positive Square. It can also take a sample larger specimen holder according to the requirements of the system.

5 Instruments

5.1 Charpy impact test machine includes film punches, specimen holder, reading devices, the pendulum locking device, the base, the level of equipment, housing, support Aircraft and other structures. 5.2 punch classification A and B, the following dimensions. a) A type of punch. punch the smooth surface of the hemisphere, spherical radius of 12.7mm, bottom circle diameter of 25.4mm. See Figure 1. b) B-type punch. punch surface smooth spherical cap, the ball radius of 12.7mm, bottom circle diameter of 19.0mm. See Figure 2. ......
