ISO 16170:2016规定了高效颗粒空气过滤器的现场试验方法，用于限制向环境的排放（例如，从核设施或气溶胶有毒或生物排放的设施）。这适用于在处理或处理有毒/放射性/生物材料的工业（包括核）设施排放到环境之前，使用这些过滤器的安装来清洁废水空气的情况。 它不包括ISO 14644？3已经涵盖的应用。 ISO 16170:2016的范围包括两种方法的细节，其中一种方法适用于高效过滤器的定期测试，高效过滤器用于保护环境的苛刻应用，如核工业。 就核应用而言，ISO 16170:2016适用于ISO 17873（核反应堆以外的应用）和ISO 26802（核反应堆）所涵盖的装置。 ISO 16170中规定的两种参考方法: 2016年不等同于，但与测试结果要满足的要求有关。在任何具体情况下，采用哪种方法取决于结果是否需要诚信测试或法定效率会计测试。 对于处理或加工放射性或有毒材料的行业，可能会产生释放风险，测试的主要目的是确认过滤器安装是否适合使用。在完整性试验（附录B）的情况下，这是为了确认有毒气溶胶不可能通过过滤器装置发生重大泄漏。 对于效率核算试验（附录C），该试验旨在准确测量MPPS颗粒尺寸范围内的去污系数。 附录B（完整性试验）中所述的参考方法要求对分散的油颗粒进行试验气溶胶，其尺寸范围主要为亚微米，在试验过程中稳定，并与其他安装部件兼容。 通过光散射仪器（光学探测器）实时测量颗粒浓度。 附录C（效率核算试验）中所述的参考方法要求对HEPA过滤介质的微粒进行试验，这些微粒的粒径范围较窄，集中在MPPS粒径范围内。通过对通过清洗膜取样过滤器获得的水溶液进行荧光分析，测量过滤器上游和下游的浓度。 应注意的是，效率会计测试的要求还包括完整性测试的要求，这被视为最低要求。 ISO 16170:2016中制定的试验方法不包括其他现场性能要求，如机械阻力、耐爆裂性或耐湿性。在高温下运行或带有特定气体流出物的特定系统可能需要特定的测试方法。 HEPA和ULPA过滤器装置的工程设计不属于ISO 16170: 2016 注:在一般通风应用的过滤器领域，ISO 29462详细全面地描述了一种方法，该方法使用扫描和颗粒计数方法来评估过滤器在颗粒级效率和压降方面的性能。这种方法和程序不适用于需要在MPPS尺寸下量化去污系数的核设施。

ISO 16170:2016 specifies in situ test methods for high efficiency particulate air filters used to limit releases towards the environment (e.g. from nuclear facilities or facilities with aerosol toxic or biological releases). This applies where installations of these filters are used to clean effluent air before discharge to the environment from industrial (including nuclear) installations where toxic/radioactive/biological materials are handled or processed.

It excludes the application already covered by ISO 14644？3.

The scope of ISO 16170:2016 includes detail of two methods, either of which applies to the periodic testing of high efficiency filters which are used in demanding applications aiming at protecting the environment, such as the nuclear industry.

In the case of nuclear applications, ISO 16170:2016 is applicable to installations covered by ISO 17873 (applications other than nuclear reactors) and ISO 26802 (nuclear reactors).

The two reference methods specified in ISO 16170:2016 are not equivalent, but related to, the requirements to be addressed by the test results. The choice of which of the two methods is adopted in any specific case depends on whether the outcome requires an integrity test or a statutory efficiency accountancy test.

For industries handling or processing radioactive or toxic materials giving rise to a risk of possible release, the main goal of the tests is to confirm that the filter installation is fit for purpose. In the case of integrity tests (Annex B), this is to confirm that no significant leakage of toxic aerosols through the filter installation is possible.

In the case of efficiency accountancy tests (Annex C), the test is designed to make an accurate measurement of decontamination factor with respect to the MPPS size range of particles.

The reference method described in Annex B (integrity test) requires a test aerosol of dispersed oil particles mainly submicrometre in size range, which is stable during the test procedure and compatible with other installation components. Particle concentrations are measured in real time by light scattering instrumentation (optical detectors).

The reference method described in Annex C (efficiency accountancy test) requires a test aerosol of particles having a narrow size range centred on MPPS size range for HEPA filter media. Their concentration both upstream and downstream the filters is measured by fluorimetric analysis of aqueous solution obtained by washing the membrane sampling filters.

It should be noted that the requirements for an efficiency accountancy test also cover the requirements of an integrity test, which is considered to be a minimum requirement.

Test methods developed in ISO 16170:2016 do not cover the other in situ performance requirements, such as mechanical resistance, bursting resistance or humidity resistance. Specific systems operating at high temperature or with specific gaseous effluents might require specific test methods.

The engineering design of HEPA and ULPA filter installations does not fall within the scope of ISO 16170:2016.

NOTE In the field of filters for general ventilation applications, ISO 29462 is a detailed and comprehensive description of a method which uses scanning and particle counting methods to evaluate the performance of a filter in terms of particle grade efficiency, as well as pressure drop. Such a method and procedure would not be applicable in those nuclear installations where quantification of the decontamination factor at MPPS size is needed.
