Facility – Manufacturing
There are five levels:
Level 1 (Process Audit)
Process Audits shall be conducted on the Quality Management System with regards to the manufacturer’s facility’s systems and in house processes, for the manufacture of product to the NS-1™ Standard and ISO/TS 29001 requirements.
Level 2 (Product Audit)
Product audits shall cover the following areas;
- NS-1™ Supplementary Requirements.
- NS-1™ Sub-Specifications.
- Mechanical Testing on selected material to verify conformance to NS-1™
i.e. Toughness, Hardness, Yield, Chemical Analysis.
- Tests to verify effectiveness of cold rolling process of threaded connections.
- Products Audits shall be conducted on equipment currently covered under NS-1™.
Level 3 (Independent Design Review to NS-1™)
For equipment not covered under NS-1™
Design review shall be conducted for this level and include requirements of Levels 1 & 2. Reviews shall cover the following:
Review of Design Drawings to ensure that the product has been designed with consideration to failure avoidance.
Evaluations are conducted based on failure modes more commonly observed when equipment is used for purposes to which they were designed, and may require calculations to be performed for determining the maximum loading conditions equipment may be subjected.
For equipment covered under NS-1™
Review of data / performance sheets for product
Level 4 (Application Approval of NS-1™ Products)
Product Application Approval (i.e. Hardbanding, Plastic Coating etc.) shall be conducted for this level
It is understood that some products do not require hardbanding or internal plastic coating - also that some facilities do not provide these services. In these cases Level 4 may be excluded.
Level 5 (Use of NS-1™ Approved Suppliers Only)
Level 5 approvals shall be granted when manufacturers satisfy the requirements of Levels 1, 2, 3, & 4 and use only approved suppliers for heat treatment and upset tubulars, etc. or perform these processes themselves as part of the audit.
