10、46182004 2 PREFACE This Standard was reviewed by the Standards Australia Committee, AG-011, Gas Components and Industrial Equipment, to supersede AG 2021998, Approval requirements for gas appliance regulators. The Standard is republished without technical alterations. The objective of this Standard
11、is to provide manufacturers, designers, regulatory authorities, testing laboratories and similar organizations with uniform minimum requirements for the safety, performance and use of gas appliance regulators. This Standard should not be regarded as a design specification or as an instruction manual
12、. In its preparation, consideration has been given to (a) continuity of satisfactory operation; (b) the prevention of fire hazards, and explosions; (c) the prevention of injury to persons or property; (d) gas rules and regulations now in force; and (e) relevant International Standards. The terms nor
13、mative and informative have been used in this Standard to define the application of the appendix to which they apply. A normative appendix is an integral part of a Standard, whereas an informative appendix is only for information and guidance. Statements expressed in mandatory terms in notes to tabl
14、es and figures are deemed to be requirements of this Standard.

17、 regulators up to 50 mm size for use on natural gas (NG), simulated natural gas (SNG), town gas (TG), tempered liquefied petroleum gas (TLP) and liquefied petroleum gas (LPG), for inlet gas pressures up to 7 kPa and outlet pressures above 0.25 kPa. They may or may not be of the lock-up type. Complia
18、nce of a regulator with these requirements does not imply that it is acceptable for use without supplemental tests in its intended application. Requirements for a regulator incorporated in a combination control is published in AG 209 (to be AS 4624). 1.2 CLASSIFICATION Regulators shall be classified
19、 according to type, class, and grade. 1.2.1 Type Two types of regulator shall be: (a) Fixed outlet pressure regulatorA regulator having one non-adjustable nominal outlet pressure (Pn) as specified by the manufacturer. (b) Adjustable outlet pressure type regulatorA regulator on which the outlet press
20、ure can be adjusted between minimum and maximum nominal outlet pressure Pn(min) and Pn(max) as specified by the manufacturer. 1.2.2 Class The range of flow rates for which a regulator readjustment is not necessary, as specified by the manufacturer. The classes shall be as listed in Table 1.1 TABLE 1
21、.1 CLASS OF REGULATOR Class Range of flow rate 0 0.006 m3/h Qm 1 0.025 Qm Qm 2 0.1 Qm Qm 3 0.5 Qm Qm 4 Fixed rate where Qm is the maximum flow rate specified by the manufacturer Accessed by UNIVERSITY OF SOUTH AUSTRALIA on 10 Mar 2008 5 AS 46182004 .au Standards Australia 1.2.3 Grade The grade of a
22、regulator shall be the maximum variation in the regulator outlet pressure specified by the manufacturer about the set pressure over the range of flow rates appropriate to its class and over the permissible inlet pressure range specified by the manufacturer. The grades shall be as listed in Table 1.2
