PR modules observe the current directives and standards

The quality control system DS/EN ISO 9001:2000 defines every process throughout our production. Moreover, the entire product range at PR electronics is produced in accordance with international standards including CENELEC, ANSI and IEC. The products observe current directives such as ATEX, EMC, LVD and the PELV/SELV standard.

The EMC policy is based on the EU directive 89/336/EEC of January 1 1996, under which the generic EMC standard EN 50081 defines the approved emission limit that the product must observe during test. Contrarily, the manufacturer has to define the limit for the immunity test himself according to the generic EMC standard EN 50 082. PR electronics' defined limit for deviation during immunity test is typically < ± 0,1 of span.      

Many companies in the processing industry demand an extended EMC immunity. Thus, every new PR module observes the NAMUR NE 21 A criterion for radio frequency interference with a burst test voltage of 2 kV.

Our complete Ex program is designed to observe the strictest safety demands. All modules with an Ex interface are constructed as safety barriers with high 3-/ 5- port galvanic isolations.

Products with UL and CSA certificates observe the standard of the legislation in the USA and Canada respectively. Naturally, the achievement of these certificates was necessary in order to become successful in North America. Moreover, FM certifies various products.

The majority of our products have been certified according to the Russian GOST standard and our Ex modules have GOST Ex approvals.

Besides meeting the requirements of the current directives and standards every product from PR electronics is guaranteed for 5 years and tested and documented individually.
