1 范围 Scope

The purpose of this European Standard is to define requirements for marking, identification, leaktightness, electrical and operational safety and mechanical resistance for sanitary tapware with opening and closing controlled electronically.

本欧洲标准的目的是对开闭电子控制的卫生龙头的标记、标识、密封性、电气和操作安全性以及机械阻力的要求进行定义。

The conditions of use for the supply system type are specified in Table 2:

供应系统类型的使用条件如表2所示:

Table 2 — Conditions of use

		限制使用	限制使用	建议操作范围	建议操作范围
		带有常开或常闭（单稳态）电磁阀的接头	带有锁存（双稳态）电磁阀的水龙头	带有常开或常闭（单稳态）电磁阀的接头	带有锁存（双稳态）电磁阀的水龙头
类型1	最小动态压力	0.05MPa(0.5bar)	0.05MPa(0.5bar)	(0.1~0.5)MPa / (1-5)bar	(0.1~0.5)MPa / (1-5)bar
类型1	最大静态压力	1MPa(10bar)	1MPa(10bar)	1MPa(10bar)	0.8MPa(8bar)
类型2	最小动态压力	0.01MPa(0.1bar)	0.01MPa(0.1bar)	(0.01~0.2)MPa / (0.1-2)bar	(0.01~0.2)MPa / (0.1-2)bar
类型1	最大静态压力	1MPa(10bar)	1MPa(10bar)	0.8MPa(8bar)	0.6MPa(6bar)
	水温	≤75℃	≤75℃	≤6℃	≤65℃

For Type 2, the manufacturer is to declare the minimum operating pressure at which opening, closing and the specified flow rate can be obtained.

对于类型2，制造商应声明可获得开启、关闭和指定流量的最小工作压力。

There is usually no acoustic classification for tapware used in supply systems of Type 2 and no specifications governing the level of noise emissions from these water installations. If supply pressures are such that excessive noise is generated it is recommended that pressure or flow regulators are fitted in the system. Or where practicable, tapware conforming to the appropriate acoustic classification are used.

在2型供应系统中使用的标签件通常没有声学分类，也没有控制这些水设施的噪音排放水平的规范。如果供应压力产生过大的噪音，建议在系统中安装压力或流量调节器。或在切实可行的情况下，使用符合适当的声学分类的标记软件。

Annex B lists possible consequences of using a product outside its recommended operating range.

附件 B 列出了使用超出其他建议操作范围的产品的可能后果。

Annex B lists possible consequences of using a product outside its recommended operating range.
