IOR updates refrigeration guidance

The Institute of Refrigeration has issued a new refrigerant code of practice to complement the BS EN 378:2008 safety standard for the refrigeration industry.

The publication in late 2008 of the BS EN 378:2008 standard - Refrigerating systems and heat pumps – Safety and environmental requirements - has led IOR to revise its A1/A2 and A3 refrigerant codes of practice.

Requirements for A2 refrigerants have been moved to the Safety Code of Practice for A2 and A3 Refrigerants (low flammable and flammable). Requirements for Carbon Dioxide R-744 are covered a separate specialist document.

The four IOR codes include:

• Carbon Dioxide
• Ammonia
• A2 and A3 Refrigerants (flammable halocarbons and hydrocarbons)
• A1 Refrigerants (non flammable halocarbons)

IOR secretary Miriam Rodway said: “The standard is often neglected by designers, installers and those altering or maintaining existing systems. The IOR Codes reinforce the standard’s technical requirements and recognise and incorporate relevant aspects of other standards.”

Wider responsibilities referred to include provisions of the Health & Safety at Work etc. Act 1974, PSSR 2000 and DSEAR 2002.

The Pressure Systems Safety Regulations (2000), the Ozone Depleting Substances Regulation and the European Regulation on Certain Fluorinated Greenhouse Gases (2006) (F Gas Regulations) impose certain obligations on the 'user' of refrigerating equipment, which are also incorporated.

Each Code includes a substantial and updated list of references to standards, regulations, legislation, heath and safety and industry guidance.

All documents are available as PDF downloads from the IOR website for £40 to non members (£20 to members).
