3. Material Standards

Materials shall meet the requirements of all applicable standards and legislation. This will include the latest revisions of: ‐

British Standards

International and European Standards

Energy Networks Association Technical Specifications

Northern Powergrid Technical Specifications.

Consideration should also be given to other Northern Powergrid design documents and the business approach to customer connections as they may differ from other Distribution Licence Holders.

Appendix 1 of this document lists the Northern Powergrid product specifications relevant for each product type.

4. Assessment Requirement

4.1 Product Assessment

All materials procured by Northern Powergrid have undergone assessment. Network products are assessed in compliance with Northern Powergrid documented procedure PRC/200/203 – Management Process for the assessment and introduction of distribution plant, equipment or materials. The type of assessment will vary depending on the complexity of the product but may include field trials, witness type/routine testing, assessment of test data and product data sheets etc. This is a fully documented system that requires appropriate authorisation.

4.2 Supplier Assessment

It is Northern Powergrid policy to carry out audits of supplier’s quality management systems when the requirement arises. This procedure is documented in PRC/200/204 – Management Process for the audit of supplier’s quality management systems. A commercial assessment of potential is also carried out prior to the placement of contract.

5. Provision of Materials

Plant and materials delivered from manufacturers shall be unloaded and stored in a way that avoids damage and exposure to moisture. Materials shall be inspected during installation and any found defective shall be replaced.

It is important to note that manufacturers may manufacture a range of similar equipment types or designation and that all may not necessarily be assessed or suitable. It is the contractors responsibility to ensure that all material meet the requirements of this document.

6. Assessed Products

6.1 Assessed List

Appendix 1 of this document details assessed products by reference, description, supplier and associated standard. The ownership and update of this list is the responsibility of Northern Powergrid who has the right to remove products and/or suppliers if necessary. This may be due to product failures or a change in company policy. Materials shall be applied in accordance with Northern Powergrid or the supplier’s installation instructions.




6.2 Alternative Manufacturers Equipment

Alternative products will require a full assessment and will be considered at the discretion of Northern Powergrid. It must be noted that additional time will be needed to complete an appropriate assessment. Information shall be provided that will allow compliance and quality assessments to be made. The level of information required will relate to the complexity of the equipment and/or materials being considered.
