标准范围

ISO 29461规定了测定旋转机械（如固定式燃气轮机、压缩机和其他固定式内燃机）进气过滤系统中使用的微粒空气过滤器性能的方法和程序。它适用于相对于0.4 μ m颗粒具有高达99.9%的初始颗粒效率的空气过滤器。根据其他标准（例如EN 1822）对初始颗粒效率较高的过滤器进行测试和分类。这些程序适用于流速在0.25 m3/s（900 m3/h）至1.67 m3/s（6000 m3/h）范围内运行的过滤器。ISO 29461-1:20 13是指静态（屏障）过滤系统，但在适当的情况下可应用于其他过滤器类型和系统。ISO 29461中使用了两种确定效率的方法-1:2013:颗粒效率(相对于颗粒数量和尺寸测量)；重量效率（装载粉尘的加权质量去除百分比。此外，来自相同过滤器的平板介质样品或介质包样品被调节(排出)以提供关于静电去除机制的强度的信息。在确定其初始颗粒效率之后，将未处理的过滤器分步装载灰尘，直到达到其最终测试压降。然后获得关于过滤器的加载性能的信息。根据ISO 29461-1:20 13获得的性能结果不能（本身）定量应用于预测效率和寿命方面的服务性能。需要考虑的影响性能的其他因素在附件中描述。

ISO 29461 specifies methods and procedures for determining the performance of particulate air filters used in air intake filter systems for rotary machinery such as stationary gas turbines, compressors and other stationary internal combustion engines. It applies to air filters having an initial particle efficiency up to 99,9 % with respect to 0,4 μm particles. Filters with higher initial particle efficiencies are tested and classified according to other standards (e.g. EN 1822). These procedures are intended for filters which operating at flow rates within the range 0,25 m³/s (900 m³/h) up to 1,67 m³/s (6000 m³/h).ISO 29461-1:2013 refers to static (barrier) filter systems but can be applied to other filter types and systems in appropriate circumstances.Two methods of determining the efficiency are used in ISO 29461-1:2013:

• particulate efficiency (measured with respect to particle number and size);
• gravimetric efficiency (percentage weighted mass removal of loading dust.

Also a flat sheet media sample or media pack sample from an identical filter is conditioned (discharged) to provide information about the intensity of the electrostatic removal mechanism.After determination of its initial particle efficiency, the untreated filter is loaded with dust in steps until its final test pressure drop is reached. Information on the loaded performance of the filter is then obtained.The performance results obtained in accordance with ISO 29461-1:2013 cannot be quantitatively applied (by themselves) to predict performance in service with regard to efficiency and lifetime. Other factors influencing performance to be taken into account are described in the annexes.
