DESCRIPTION

BS 4105:1990


This standard BS 4105:1990 Specification for liquid carbon dioxide, industrial is classified in these ICS categories:
  • 71.060.20 Oxides
  • 71.100.20 Gases for industrial application

This British Standard specifies two types of carbon dioxide for industrial use. Type 1 is suitable for industrial non-food applications, e.g. purging, inerting, life raft inflation. Type 2 is a higher quality grade which is also suitable for industrial food applications, e.g. beverages, gas packaging, food freezing and chilling.

NOTE 1 Type 2 carbon dioxide is covered by the specific and general criteria of purity laid down in The Miscellaneous Additives in Food Regulations 1980 (SI 1980 No. 1834) in which carbon dioxide is referred to as E290.

This standard does not apply to carbon dioxide for:

  1. medical use, for which a specification is included in the British Pharmacopoeia;
  2. fire fighting, for which BS 6535-1 applies;
  3. welding.

NOTE 2 Throughout this standard, concentrations expressed by mass or volume are at a temperature of 20 °C and 101.3 kPa1) pressure.

NOTE 3 The titles of the publications referred to in this standard are listed on the inside back cover.


Two grades are specified for industrial uses excluding welding, fire extinguishing or medical; methods of sampling and analysis are described in appendices. Type 2 is suitable for food applications.
