Foreword

This standard replaces GB/T 8168-1987 "package cushioning material static compression test method." This standard compared with GB/T 8168-1987, the main changes are as follows. --- Increase in the content references, terminology, test equipment; --- Increasing the test samples were randomly selected requirements; --- Modify the number of tests with the test sample; --- Increase the recommended test sample sizes; --- A predetermined load is applied to increase the amount of B Test Method; --- Increasing the thickness measurements of the test requirements of the test data. Appendix A of this standard is an informative annex. This standard by the National Packaging Standardization Technical Committee (SAC/TC49) and focal points. This standard was drafted. the machine Productivity Promotion Center, Shenzhen MYS Environmental Protection Technology Co., Ltd, China Export Commodities Packaging graduate School. The main drafters of this standard. yellow snow, Liu Ping, Cai Shao Ling, Li Jianhua, Zhang Jian, Ding Jiayi. This standard replaces the standards previously issued as follows. --- GB/T 8168-1987. Cushioning material for packaging static compression test method

1 Scope

This standard specifies the cushioning material for packaging static compression test principle test methods, test equipment, test samples, test procedures and test Inspection reports and other content. This standard applies to assess performance and cushioning protection under static load cushioning material in the process of circulation of the contents of the product ability. This standard applies to the shape of the packaging with cushioning material may be massive, flaky, filamentous, granular and molded parts in the form of EPS, EPE And other soft, hard cushion material not suitable for corrugated board, EPE film, metal springs and shock-proof rubber.
