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
Products covered by PMUC (EDF) approval
The products concerned are those that can be used in nuclear or thermal power plants during:
- Manufacturing
- Assembly
- Maintenance
- Operation
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.

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.
Who must have a PMUC product approved?
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.
All products and materials likely to enter a nuclear power plant may be affected. The 24 product categories are: glues, varnishes, paints, anti-seize products, cleaning products, decontamination products, protective products, lubricants, oils, greases, degreasers, solvents, gaskets, sealants, leak detection products, leak sealing products, abrasives, plastics, expanded foams, expanded polymers, temporary coatings, protective films, temporary marking products, wiping consumables (rags, wipes).
PMUC certification is an official procedure that certifies that a product or material complies with EDF requirements for use in nuclear or thermal power plants. This certification guarantees that the product meets the contamination thresholds for halogens (chlorine, fluorine, bromine, iodine), sulfur, and silicones, in order to avoid any risk of corrosion, pollution, or accidents in controlled areas.
The main steps are:
- Definition of the product scope and collection of documents (MSDS, TDS).
- Chemical analysis (halogens, sulfur, silicones) by an accredited laboratory.
- Preparation of a test report compliant with EDF standards.
- Submission of the approval application to EDF.
- Receipt of the approval decision, valid for 5 years.
FILAB is a COFRAC ISO 17025 accredited laboratory and, more importantly, is recognized by EDF (EDF approval) to perform PMUC analyses. FILAB's support allows us to:
- Guarantee reliable and traceable analysis,
- Benefit from technical support for preparing the file,
- Optimize processing times,
- Secure the process in response to EDF's strict requirements.
FILAB combines modern, standardized techniques to quantify targeted contaminants:
- ICP-AES or ICP-MS for halogens and sulfur, often after mineralization,
- Ion chromatography (IC) for certain halogen ions,
- FTIR (infrared spectroscopy) to detect silicones,
- Complementary methods depending on the matrix (paints, temporary products, etc.)
