Summary This standard specifies test methods for the stability, strength and durability of office work chairs. This standard specifies guidance for testing force values, number of cycles, etc. Test methods are developed for products that are fully assembled and ready for use. The dimensions in the test method apply only to office work chairs intended for adults. The test method includes the forces acting on the different components, simulating various usage states of the office work chair during normal use and foreseeable misuse. The test method is used to evaluate the performance of office work chairs, regardless of product material, structural design, or production process. Test results are only valid for the sample being tested. When test results are to be used for other similar products, it is important that the test sample is representative of a production model. Testing in accordance with this standard is performed to enable the product to perform in the intended use environment

1 Scope

This standard specifies the test methods for the stability, strength and durability of office work chairs. This standard gives the test force value, cycle times Counting guidance. Test methods are developed for products that have been fully assembled and ready for use. The dimensions in the test method only apply to office work chairs for adults. The test methods include forces acting on different components, simulating various uses of office work chairs during normal use and foreseeable misuse Usage status. The test method is used to evaluate the performance of office work chairs without regard to product materials, structural design and production process. The test result is only valid for the tested sample. When the test results need to be used for other similar products, then the test sample can represent a certain production The model is very important.

This test method is Developed based on testing of unused products or components. If the test method is proved to be reasonable and effective, it can also be applied to product defects survey. See Appendix B for the design data of the seat loading pad, and Appendix C for the design data of the stability loading pad. This standard does not contain requirements for products. The requirements can be specified in separate requirements documents. If there is no required document, the force value See Appendix A (Informative) for the number of cycles. These loads and cycles are suitable for any adult, regardless of their weight and usage The length of time to use the product. This standard does not specify the acceptance test method for individual parts of office work chairs. This standard does not include performance aging and degradation tests. The test method does not evaluate the durability of soft packages, such as. filling materials and cladding material.
