P-marking of air filters
The P-mark is a certification for air filters intended for ventilation systems within the classification groups ISO ePM1, ISO ePM2.5 and ISO ePM10. The P-mark is RISE own quality label, which is found on many products and services, of which air filters are one.
Purpose
The P-marking is a way of showing how requirements in Swedish building regulations and in voluntary requirements are fulfilled. P-marking of air filters is a voluntary commitment which means that the quality of the filters is controlled by an independent party, which contributes to increasing customers’ confidence in the product.
Method
The P-marking is based on certification rule CR 055 ”Air filter for ventilation plants”. In order for an air filter to be P-marked, it must first be tested with regard to: initial pressure drop and filter class according to ISO 16890, energy consumption according to Eurovent 4/21 and long-term characteristics that are evaluated over three months with regard to degree of filtration efficiency.
In addition, the manufacturer is required to have a functioning quality system for its production. The manufacturer’s factory production control is monitored; an agreement is signed with RISE on continuous inspections and thereafter RISE performs external inspection every year at the production site, including sampling for test in accordance with ISO 16890.
Deliveries
If the requirements of the certification rule are fulfilled, a certificate may be issued and the filter could then be marked with the P-mark. Certificates can include a product group, also called a product family, and can thus include more articles than the one being tested. The certificate is valid for five years and can then be renewed for further five-year periods.
