燃气和/或燃油燃烧器和电器的安全性和控制设备.一般要求

[中文适用范围]： 本文件规定了使用天然气、人造煤气或液化石油气 (LPG) 的燃气燃烧器和燃气燃烧器具的控制装置的安全、结构、性能和测试要求。 本文件适用于最大工作压力不超过 500 kPa 的控制器。 本文件提供了一般要求，旨在作为 ISO 23551 和 ISO 23552 系列中特定控制标准的基础。 其中包括： ——自动和半自动燃气阀； ——燃气热电火焰监控控制； ——天然气和油/空气比例控制； ——气压调节器； ——手动燃气阀； ——机械式燃气恒温器； ——多功能气体控制装置； ——空气和气体压力传感装置； ——排气阀； ——燃气阀验证系统。 本文件仅涵盖型式测试。 本文件还适用于在设备内部使用的气体快速连接器 (GQC)，连接尺寸不超过 DN 25，最大工作压力不超过 100 kPa。 GQC 包括： ——管对管连接； ——控制连接管； - 管子与管件的连接。 本文件不适用于液体燃料的机械控制装置。 也不适用于腐蚀性气体和废气。 [外文原描述]： ISO 23550:2018 specifies safety, construction, performance and testing requirements for controls for gas burners and gas burning appliances for use with natural gas, manufactured gas or liquefied petroleum gas (LPG). ISO 23550:2018 applies to controls for use at maximum operating pressures up to and including 500 kPa. This document provides the general requirements that are intended to be the basis for the specific control standards found in the ISO 23551 and ISO 23552 series. These include the following: - automatic and semi-automatic gas valves; - gas thermoelectric flame supervision controls; - gas and oil /air ratio controls; - gas pressure regulators; - manual gas valves; - mechanical gas thermostats; - multifunctional gas controls; - air and gas pressure-sensing devices; - gas vent valves; - gas valve-proving systems. ISO 23550:2018 covers type testing only. ISO 23550:2018 is also applicable to Gas Quick Connectors (GQC) for use inside appliances with connections up to, and including DN 25, and a maximum operating pressure up to and including 100 kPa. GQCs include: - tube to tube connections; - tube to control connections; and - tube to fitting connections. ISO 23550:2018 does not apply to mechanical controls for use with liquid fuels. It is also not applicable to corrosive and waste gases.
