BS 5422:2009

This standard BS 5422:2009 Method for specifying thermal insulating materials for pipes, tanks, vessels, ductwork and equipment operating within the temperature range -40°C to +700°C is classified in these ICS categories:

• 23.020.01 Fluid storage devices in general
• 27.220 Heat recovery. Thermal insulation
• 91.100.60 Thermal and sound insulating materials

This British Standard describes a method for specifying requirements for thermal insulating materials on pipes, tanks, vessels, ductwork and equipment for certain defined applications and conditions within the temperature range −40 °C to +700 °C. It also specifies some physical requirements for the insulating materials. It is intended for use by designers, specifiers, contractors and manufacturers of thermal insulation.

This British Standard does not apply to pipelines that are embedded underground, nor does it refer to the insulation of building construction.
