Scope: This standard specifies the classification and model preparation, technical requirements, test methods, inspection rules, marking, packaging, transportation and storage of bottled liquefied petroleum gas pressure regulators (hereinafter referred to as pressure regulators). This standard is applicable to household bottled liquefied petroleum gas pressure regulators with an inlet pressure of 0.03MPa ~ 1.56MPa, an outlet pressure of 2.8OkPa ± 0.5OkPa, a rated flow rate less than or equal to 2m/h, and an operating ambient temperature of -20 ℃ ~ 45 ℃. (hereinafter referred to as household pressure regulator); and the inlet pressure is 0.03MPa~1.56MPa, the outlet pressure is 2.8OkPa±0.5OkPa or 5.OOkPa±0.9OkPa, the rated flow is less than or equal to 3.6m/h, and the operating ambient temperature is - Non-household bottled liquefied petroleum gas pressure regulator between 20 ℃ and 45 ℃ (hereinafter referred to as non-household pressure regulator). All pressure values mentioned in this standard that are not marked refer to gauge pressure.
