NOTE 1 It is recognized that miscellaneous components not specifically covered herein can be examined to meet the criteria of this document and tested according to the appropriate functional tests.

NOTE 2 All references to pressure in this document are considered gauge pressures unless otherwise specified.

NOTE 3 This document is based upon a working pressure for natural gas as a fuel of 1,6 MPa (16 bar). Other working pressures can be accommodated by adjusting the pressure by the appropriate factor (ratio). For example, 2 Mpa (20 bar) working pressure system will require pressures to be multiplied by 1,25.
