PD CEN ISO/TR 13881:2011

This standard PD CEN ISO/TR 13881:2011 Petroleum and natural gas industries. Classification and conformity assessment of products, processes and services is classified in these ICS categories:

• 75.080 Petroleum products in general
• 75.020 Extraction and processing of petroleum and natural gas

This Technical Report describes:

• two classification methods (one based on calculated risk, the other on judgement of risk) which may be used to determine the appropriate conformity assessment system for products, processes and services;

• a set of five conformity assessment systems from which the most suitable is chosen when conformity assessment of products, processes and services is required.

NOTE Alternative classification models may be used provided their results are consistent with the conformity assessment systems to be applied.
