6. Description of content: 
 1.1 This standard specifies performance, safety and constructional requirements for 
low-pressure regulators of the single-sta ge type intended for use with liquefied 
petroleum gas mixtures in the vapour phase and designed for a set outlet pressure 
of 2.8 kPa and a flow not exceeding 10 kg/h 
 1.2 With the exception of the design and construction requirements and gas 
tightness, the requirements of this standa rd do not apply to pressure regulators 
used with liquefied petroleum gas mixtures in the vapour phase and designed for an outlet pressure greater than 2.8 kPa 
NOTE 1 Unless otherwise stated, all pressures given in the standard are gauge pressures.  
NOTE 2 Pressure regulators intended for use in welding, cutting and allied processes are 
not covered
