Method for specifying thermal insulating materials for pipes, tanks, vessels, ductwork and equipment operating between -40 degrees C to +700 degrees C.
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 degrees C to +700 degrees C. It also specifies physical requirements for the insulating materials.
This standard is intended for use by 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.
The changes to this standard from the previous edition are the following.
- All tables of insulation thicknesses have been reviewed. The assumptions on which the tables are based are given in each case.
- The previous “economic insulation thicknesses” have been revised in the context of their potential to limit carbon dioxide emissions, whilst maintaining due
consideration of both economic and practical factors. This new approach is referred to as the “environmental thickness” calculation.
- The frost protection tables have been revised to reflect more accurately UK design and operating conditions
This British Standard supersedes BS 5422:1990, which is withdrawn.
The methods of calculation used in this standard have been revised to harmonize with the methods in BS EN ISO 12241.
This standard includes the following cross references:
BS 476-6:1989, BS 476-7:1997, BS 476-12:1991, BS 3177, BS 4370-2:1993, BS 5970:2001, ISO 1182.
