Control and certification analysis laboratory PMUC
Your needs: check the conformity of your PMUC products by a competent laboratory approved by EDF
PMUC products (Products and Materials Used in Electric, Nuclear or Thermal Power Plants) are non-metallic products or materials in direct contact with metallic materials or circuits. They have a potentially corrosive effect on steel when they contain halogenated or sulphurous species. The PMUC control or certification analysis is used to prevent and control the risk of corrosion in the metal circuits of power plants.
In order to be authorised to be placed on the market, PMUC products must be approved by EDF, after analyses have been carried out in an EDF-approved laboratory for PMUC.

PMUC product control and monitoring analysis
Which products are concerned? Which families?
The products concerned are those that can be used in power plants during manufacturing, assembly, maintenance or operating operations.
There are 24 categories of products classified as PMUC by EDF: glues, varnishes/paints, anti-seize agents, cleaning/decontamination/protection products, plastics, gaskets, leak detection or sealing products, abrasives, etc.

EDF approval
FILAB: an EDF-approved laboratory for PMUC analysis of your materials
The PMUC chemical analyses carried out by FILAB comply with EDF procedure D5713 / DJX / RB 90 0295.
The checks carried out by the laboratory consist in analysing the halogen (Fluorides F-, Chlorides Cl-, Bromides Br-) and sulphur content of Products and Materials for Use in Power Plants (PMUC) in order to verify compliance with the EDF - PMUC chemical specifications.
FAQ
The PMUC test is only used to check that a product complies with PMUC requirements if it has already been approved for use for less than 5 years.
The PMUC control or approval analysis consists of determining the halogen (Fluorine / Fluorides, Chlorine / Chlorides, Bromine / Bromides) and sulphur content of products and materials intended for use in power plants, in accordance with EDF protocols specific to the product family.
Once the analysis has been carried out, a report is drawn up and sent to the customer to submit the results to EDF for PMUC approval.
