办公家具.办公椅子.测定稳定性、强度和耐久性的试验方法

[中文适用范围]： 本国际标准规定了测定办公椅稳定性、强度和耐用性的测试方法。 对于这些测试的力、周期等的选择给出了指导。 这些测试旨在应用于完全组装并可供使用的家具。 测试中的尺寸适用于成人办公椅。 测试包括对物品的各个部分施加模拟正常功能使用的力，以及可以合理预期发生的误用。 这些测试旨在评估性能，而不考虑材料、设计/结构或制造工艺。 测试结果仅对所测试的物品有效。 当测试结果打算应用于其他类似物品时，测试样本必须能够代表生产模型，这一点很重要。 根据本国际标准进行的测试旨在证明该产品在其预期环境中提供令人满意的服务的能力。 这些测试是针对尚未使用的单元/组件开发的。 然而，如果合理的话，它们可以用于故障调查。 给出了座椅负载垫设计（附件 B）和稳定性负载垫设计（附件 C）的数据。 本国际标准没有给出任何产品要求。 这些可以在需求文档中指定。 如果不可用，附件 A（资料性）中建议了可能的力和周期。 这些力和循环可用于成年人，无论其体重和工作时间如何。 本国际标准没有规定椅子部件的型式认可测试。 不包括老化和降解的评估。 这些测试并非旨在评估室内装饰（即填充材料和覆盖物）的耐用性。 [外文原描述]： ISO 21015:2007 specifies test methods for determining the stability, strength and durability of office work chairs. Guidance is given on the choice of forces, cycles, etc., for these tests. The tests are designed to be applied to an article of furniture that is fully assembled and ready for use. The dimensions in the tests are applicable to office work chairs intended for adult persons. The tests consist of the application, to various parts of the item, of forces simulating normal functional use, as well as misuse that can reasonably be expected to occur. The tests are designed to evaluate properties without regard to materials, design/construction or manufacturing processes. The test results are valid only for the article tested. When the test results are intended to be applied to other similar articles, it is important that the test specimen be representative of the production model. Tests carried out according to ISO 21015:2007 are intended to demonstrate the ability of the item to give satisfactory service in its intended environment. The tests have been developed for units/components that have not been in use. However, when properly justified, they can be used for fault investigation. Data are given for the design of seat loading pads and for the design of stability loading pad. ISO 21015:2007 does not give any product requirements. These can be specified in a requirements document. If this is not available, possible forces and cycles are suggested. These forces and cycles can be used for adults regardless of their weight and number of working hours. ISO 21015:2007 does not specify type approval tests for chair components. Assessment of ageing and degradation is not included. The tests are not intended to assess the durability of upholstery, i.e. filling materials and covers.
