BS 5970:2012

This standard BS 5970:2012 Thermal insulation of pipework, ductwork, associated equipment and other industrial installations in the temperature range of -100°C to +870°C. Code of practice is classified in these ICS categories:

• 23.040.01 Pipeline components and pipelines in general
• 91.100.60 Thermal and sound insulating materials
• 27.220 Heat recovery. Thermal insulation

This British Standard gives recommendations for thermal insulation of pipework, ductwork, associated equipment and other industrial installations in the temperature range −100 °C to +870 °C.

The prime focus of each section within this British Standard is:

• design (Section 2), for design consultants and specifiers;

• site considerations (Section 3), for all users;

• application (Section 4), for mechanical contractors and thermal insulation contractors;

• post-installation inspection (Section 5), for operators.

It does not cover structural insulation of buildings and cold stores, fire protection of structures, refractory linings of plant, aircraft and all external underground mains.

NOTE Annex A provides further guidance on adhesives. Annex B provides guidance on water vapour pressure and the relation to water vapour barriers. Annex C provides guidance on the water vapour diffusion resistance ratio. Annex D gives illustrative examples of termination methods for hot and cold pipework.
