本欧洲标准规定了高达2000升体积的间接加热，不通风（封闭式）储水式热水器的结构和性能要求和试验方法，适用于在0.05MPa和1.0MPa之间的压力下与供水连接MPa（0.5巴和10巴），并配有控制和安全装置，旨在防止储存的饮用水的温度达到95°C。 虽然主要用于直接加热的储水式热水器不在本标准的范围内，但它确实允许提供用于辅助使用的电加热元件

This European Standard specifies the constructional and performance requirements and methods of test for indirectly heated, unvented (closed) storage water heaters of up to 2 000 l volume suitable for connection to a water supply at a pressure between 0,05 MPa and 1,0 MPa (0,5 bar and 10 bar), and fitted with control and safety devices designed to prevent the temperature of the stored drinking water from reaching 95 °C. Whilst storage water heaters intended primarily for direct heating are not covered by this standard, it does allow the provision of electric heating elements for auxiliary use.
