Defines criteria for design, construction, materials and testing of seamless aluminium alloy containers with water capacity between 0.5 litre and 15 litres and up to and including 300 bar charging pressure at 15 degrees C, for conveying and storing gases under pressure for use in the following portable applications: for use in aircraft; life raft inflation apparatus; fire extinguishers; resuscitation apparatus; breathing apparatus and underwater breathing dress apparatus. Includes annexes that give examples of design calculations, a description of methods for pressure testing containers, a description of methods for ultrasonic defect detection, thickness measurement and model forms of design and acceptance certificates.

This part of BS 5045 specifies requirements for the materials, design, construction and testing of seamless aluminium alloy containers of water capacity greater than 0.5 litre up to 15 litres and up to and including 300 bar1) charging pressure at 15 °C, for the conveyance and storage of gases under pressure used in the following portable applications:

  • for use in aircraft;
  • for breathing apparatus;
  • for underwater breathing dress apparatus;
  • for resuscitation apparatus;
  • for fire extinguishers;
  • for life raft inflation apparatus.

It includes annexes giving examples of design calculations, a description of the methods for pressure testing containers, a description of the methods for ultrasonic defect detection and thickness measurement and model forms of design and acceptance certificates.

It does not cover the design and manufacture of portable fire extinguishers having a working pressure up to and including 25 bar at 60 °C.
