We use the Institute of Mechanical Engineers as our PCN level 3 cover.

Clean Room Facilities

We clean and pack to a wide range of requirements i.e from good commercial grade cleaning and packing through to both military and civil, nuclear primary plant packing requirements. 

 We offer cleaning and swabbing to verify specific ionic contamination levels for the control of fluorides, chlorides and sulphates.

Cleaning processes include:

• Hot deionised water tank facilities.
• Solvent wash processes.
• Ferritic contamination control and inspection.

Controlled Environment BS EN ISO 14644-1.

We primary pack to DEF STAN 81-41 military packing levels P & N, to meet the requirements of short, medium and long term storage.

Hydrostatic Pressure Testing

Hydrostatic pressure testing up to a maximum of 300 Bar absolute.

Our hydrostatic pressure testing capability also meets the cleanliness requirements for Nuclear Reactor Plan components with the controls associated with water quality and elastomeric material compliance used for sealing.
