Applies to a minimum gauge pressure rating of 60 KPa and a maximum gauge pressure rating of 4,2 MPa. Automatic electrical pressure sensing controls for equipment not intended for normal household use, but which nevertheless may be used by the public, such as equipment intended to be used by laymen in shops, in light industry and on farms, are within the scope of this standard.<\/p>\n
