For første gang har vi nå en global standard!
ISO 16890 definerer testprosedyrer og et klassifikasjonssystem for luftfilter som brukes i generelle ventilasjonssystemer. Denne nye standarden erstatter de to eksisterende standarder: ASHRAE 52.2 (som er dominerende i USA), og EN779:2012 (som er dominerende i Europa). Begge disse standardene sameksisterer i Asia og i Midtøsten.
There are important differences between the ISO16890 standard and the existing standards.
- In several aspects, the new test procedures are more demanding than the existing standards. This will lead to higher filter performance, improved indoor air quality (IAQ) and greater protection of human health.
- The new test procedures are more closely related to real-world filter performance.
- The classification system is related to filter performance against three different sizes of particles.
- Importantly, the smallest particle fraction of the three, so called PM1, best represents the very fine particles that are known to be the most harmful to human health.
As global leader of the air filter industry, Camfil totally support the introduction of the new standard. It is clear that implementation of ISO16890 will bring real benefits for specifiers, purchasers and users of air filters.
