means an appliance as defined in SANS 1539;



means the American Society of Mechanical Engineers;


"authorised person"

means a person who is registered as competent within the scope of work for which an organisation approved by the chief inspector has registered that person;



means a written declaration of conformance to these Regulations;



includes materials, design, fabrication, modification, repair, installation, examination, inspection, testing and certification;


"dangerous substance"

means a substance defined and classified as such in terms of SANS 10228;


"design pressure"

means the gauge pressure used in the design formulae to determine the dimensions of the component parts of the pressure equipment;


"design temperature"

means the temperature used in the design formulae to determine the dimensions of the component parts of the pressure equipment;


"design verification"

means verification that the pressure equipment complies with the applied design of the relevant health and safety standard and the requirements of these Regulations;


"fire extinguisher"

means a rechargeable container which has a fire extinguishing substance that is expelled by the action of internal pressure for the purpose of extinguishing a fire;



means gases, liquids, vapours in pure phase and mixtures thereof and may contain solids in suspension;



means gases, liquefied gases, gases dissolved under pressure, vapours, and those liquids whose vapour pressure at the design temperature is greater than 50 kPa above normal atmospheric pressure;


"gas system"

means an assembly of tubes, pipes or similar ducts, fittings and valves for the reticulation, circulation and conveyance of a gas, excluding a pressure vessel or transportable gas container connected to the system;


"latent defect"

means a fault inherent in pressure equipment, resulting from deficiencies in the design or manufacturing process that may cause a health and safety risk;



means any person who has overall control and is responsible for the construction of the pressure equipment;



means any change to the original design conditions of pressure equipment, including re-rating, or the addition or removal of elements that could affect the integrity of the pressure equipment, and modify has a corresponding meaning;



means glass, thermoplastic or thermosetting polymeric reinforced and un-reinforced materials or combinations thereof;



means piping or a system of piping designed for the transport and distribution of any fluid from an installation that is onshore or offshore, starting from and including the last isolation device located within the confines of the installation, including all the auxiliary equipment designed specifically for that pipeline;



means pipes, tubes or flexible pressure hose elements intended for the transport or distribution of any fluid at a pressure of 50 kPa or above when connected together for integration into a system, including heat exchangers consisting of pipes for the purpose of cooling or heating air;


"pressure accessory"

means devices with an operational function having pressure-bearing housing;


"pressure equipment"

means a steam generator, pressure vessel, piping, pressure accessory and safety accessory, transportable gas container, and fire extinguisher and includes, but is not limited to, an accumulator, a hot water geyser, and hyperbaric chambers;


"pressure vessel"

means a housing designed and manufactured to contain a fluid under a design pressure equal to or greater than 50 kPa;


"provincial director"

means the provincial director as defined in regulation 1 of the General Administrative Regulations promulgated by Government Notice No. R. 1449 of 6 September 1996;



means activities undertaken to determine appropriate design parameters for pressure equipment where such data is unknown or unavailable;



means restoration to original standard by the application of heat or welding to any pressure equipment, or the replacement of expanded tubes, and in the case of non-metallic equipment it means the application of heat, welding, solvent cement, laminate or curing of thermo-set;



means any change in the design parameters of pressure equipment which affects the certification;



means the conveyance of gas by pipeline with a general operating pressure of no more that 200 kPa to the ultimate points of consumption;
