Product Inspection
Summary:
The standard content includes four parts: 1) Technical specifications, requirements, and a grading system based on particle size filtration efficiency; 2) Grading efficiency testing and flow resistance testing; 3) Determination of weight efficiency and the relationship between flow resistance and corresponding dust capacity changes.
In recent years, more and more foreign customers require domestic manufacturers to provide ASHRAE 52.2 test reports when purchasing filters and air purifiers. Shangdu Certification has also handled this test report for many export enterprises.
ISO 16890 standard content
The standard content includes four parts:
1) Technical specifications, requirements, and a classification system based on particle size filtration efficiency;
2) Classification efficiency testing and flow resistance testing;
3) Determination of weight efficiency and the relationship between flow resistance and corresponding dust holding capacity changes;
4) Methods for static electricity elimination and measurement of minimum classification test efficiency.
Scope of ISO 16890
Applicable products: general air filters, part of electrostatic filters can be tested;
Applicable range: air volume 900m3/h - 5400m3/h, outlet size: no more than 610mm × 610mm.
What are the differences between the ISO 16890 standard and existing standards?
1. Compared to existing standards, the new testing method has higher requirements in many aspects. This will raise the performance requirements for filters, thereby better improving indoor air quality and protecting human health.
2. The new testing method is closer to the operational performance of air filters in real application environments.
3. The classification method targets the filter performance for three different particle size categories (PM1, PM2.5, PM10).
4. More importantly, the smallest particle size segment among the three types of particles, commonly referred to as PM1, is the ultrafine particulate matter that is most harmful to human health.
