NOTE 1 For appliances containing thermostatically operated switches 7.3.4 is to be observed.
NOTE 2 If a thermostat is integrated in an appliance which it does not control, it is to be treated according to 7.2.4 or 7.3.4.14.
注1：对于含有恒温操作开关的器具应参见7.3.4。
注2：如果温控器装在不是由它控制的器具内的，按7.2.4和7.3.4.14处理。
7.2.5 Thermostats – Alternative procedure to that specified in 7.2.4
For thermostats following this alternative procedure the subclauses 4.2.3.2, 4.2.3.4 and the flow diagram of Figure 9 are not applicable.
温控器-替代7.2.4规定的程序
对于采用以下替代步骤的温控器，4.2.3.2, 4.2.3.4和图9的流程不适用。
7.2.5.1 For thermostats, separate or incorporated in a control box, e.g. with timer, intended to be integrated in a fixed room heating installation, the manufacturer shall specify the maximum operating switching rate. The click rate N shall be derived from this specification. Failing that, a click rate N = 10 shall be used, and Lq shall be determined, see 4.2.2.2.
对于单独的或装在控制箱内的，例如同计时器一起，打算装在固定的房间加热装置内的温控器，制造商应规定最大的开关操作速率。喀呖声率N由此规定值得出，否则，应使喀呖声率N=10，在确定Lq。见4.2.2.2.
The thermostat shall be caused to operate for 40 contact operations (20 opening and 20 closing), either manually by actuating of the temperature setting means, or automatically by e.g. a hot/cold blower.
应通过手动地操作温度设定装置或通过如热/冷吹风机等方式自动滴引起温控器发生40次接触操作（20次打开和20次关闭）。
The amplitude and duration of the disturbance shall be measured for the lowest rated current of the thermostat. In the absence of a marked or a declared minimum rated current, a current equal to 10 % of the maximum rated current is used. The amplitude of no more than 25 % of the disturbances shall exceed the Lq level. For thermostats which have an acceleration resistor incorporated, the same measurements shall be performed in addition without any separate load connected.
骚扰幅度和骚扰持续时间应在温控器最小额定电流下测量，如果没有标明或声明最小额定电流，应使其等于最大额定电流的10%。不超过四分之一的骚扰的幅度可以超过Lq电平。对于装有加速电阻器的温控器应在不接任何单独加热器时进行同样的附加测量。
When, in practice, the thermostat may be used together with inductive loads (e.g. relay,contactor) all measurements shall be performed using such a device, having the highest coil inductance allowed for by the manufacturer’s specification.
实践中，当温控器可能与感性负载（如继电器、接触器）一起使用时，所有测量应在制造商说明书中允许的有最大线圈电感的装置上进行。
Prior to test, it is essential that the contacts shall be operated for a hundred times with the rated load.
测试之前，用额定的负载使触点运行一百次是必要的。
NOTE This is to ensure that the levels of disturbance are representative of those encountered in normal operations.
注：这是为了保证能重现在正常运行中遇到的骚扰电平。
7.2.5.2 Thermostatically controlled three-phase switches
Thermostatically controlled three-phase switches shall be treated as thermostats (see 7.2.5.1). Where no manufacturer’s specification is given, a clickrate N = 10 shall be used.
恒温控制的三相开关
恒温控制的三相开关应作为温控器处理（见7.2.5.1）。如果制造商没有给出规定，应使喀呖声率N=10.
7.2.5.3 Thermostatically controlled portable and removable room heating appliances
For portable and movable room heating appliances the manufacturer shall specify the maximum operating switching rate. The click rate N shall be derived from this specification, and the procedure in 7.2.5.1 shall be followed.
恒温控制的便携式和可移动式房间加热器具
对于便携式和可移式房间加热器具，制造商应规定最大的转换调节速率。喀呖声率N由此规定值得出，并应按照7.2.5.1规定的步骤（测量）。
Where no manufacturer’s specification is given, a click rate N = 10 shall be used, following the procedure in 7.2.5.1, or the click rate N shall be determined for a duty-cycle of (50± 10) % of the control device. The procedure of Figure 9 shall be followed.
当制造商没有给出规定时，应使喀呖声率N=10，并按照7.2.5.1规定的步骤（测量）。或者又控制装置(50± 10) % 的工作周期得出喀呖声率N,并按照图9的步骤（测量）。
The power range switch, if any, shall be in the lowest position.
如果有功率范围开关，应设定在最小档位。
Prior to test, it is essential that the contacts shall be operated for a hundred times with the rated load.
NOTE This is to ensure that the levels of disturbance are representative of those encountered in normal operations.
测试之前，用额定的负载使触点运行一百次是必要的。
注：这是为了保证能重现在正常运行中遇到的骚扰电平
