标准摘要
[中文适用范围]： 本文件规定了用于燃气燃烧器和燃气燃烧器具（以下简称“恒温器”）的机械燃气恒温器的安全、结构、性能和测试要求。本文件适用于公称连接尺寸最大为 DN 50（含），声明最大入口压力最大为 50 kPa（含），用于天然气、人造气或液化石油气 (LPG) 的机械燃气恒温器。它不适用于腐蚀性气体和废气。本文件适用于机械恒温器： — 通过一体式燃气阀直接或间接控制燃气流量，并且不需要外部电能来运行； — 用于恒温器不直接暴露在室外环境中的燃气器具；以及 — 用于操作控制功能。本文件仅涵盖型式试验。 [外文原描述]： This document specifies safety, construction, performance and testing requirements for mechanical gas thermostat intended for use with gas burners and gas burning appliances hereafter referred to as “thermostats”. This document applies to mechanical gas thermostats of nominal connection sizes up to and including DN 50 with declared maximum inlet pressures up to and including 50 kPa, for use with natural gas, manufactured gas or liquefied petroleum gas (LPG). It is not applicable to corrosive and waste gases. This document applies to mechanical thermostats: — controlling the gas flow directly or indirectly through an integral gas valve, and which do not require external electrical energy for their operation; — used on gas appliances where the thermostat is not directly exposed to the outdoor environment; and — which are intended for operating control functions. This document covers type testing only.
