Purpose
P-marking of limestone for liming of lakes and wetlands is a voluntary commitment that means that the quality of the limestone is checked by an independent party, which contributes to increasing customers' confidence in the product.
The purpose of the certification rule is for manufacturers and users of the limestone intended for lakes and wetlands to be able to detect / choose limestone with good efficiency and with a low content of environmentally hazardous metals.
The certification rule SPCR 155 is based on current standards and the Swedish Agency for Marine and Water Management's regulations on liming of lakes and watercourses HVMFS 2013: 27 and Liming of lakes and streams - Handbook 2010:2.
Method
In order to P-mark a limestone, the product must first be type-tested by RISE, and an initial audit inspection carried out to ensure that the manufacturer has the competence and ability to manufacture products that meet the requirements of SPCR 155. There are also requirements that the manufacturer has a working quality system for its production. The manufacturer's control system is monitored: an agreement is signed by RISE and the manufacturer on continuous audit inspections and testing and thereafter an external audit is carried out every year at the manufacturer site, including sampling and testing according to SPCR 155.
Deliveries
After an initial type test, audit inspection and document review have been carried out and any non-conformities have been corrected by the manufacturer, a certificate is issued and an agreement on continuous supervision is drawn up with RISE. Then the opportunity is also given to use the certification mark (P-mark). Every year, RISE then conducts an external audit that results in an audit report and a test report.
