3 Terms and definitions
This clause of Part 1 is applicable except as follows. 3.1 Definitions relating to physical characteristics Replacement: 3.1 .9 normal operation operation of the appliance under the following conditions. The appliance is filled with dry textile material having a mass equal to the maximum mass stated in the instructions, and with the maximum quantity of water for which it is constructed. However, if the power input or current is higher when only 50 % of the textile material is used, the appliance is operated with this load instead if this gives more unfavourable conditions than the full load during the test of Clause 1 1 . Note 1 01 to entry: For some appliances incorporating a programmer, using the 50 % reduced load may result in automatic selection of a reduced wash programme. The temperature of the water is · 65 C ± 5 °C for appliances without heating elements; · 1 5 °C ± 5 °C for appliances without heating elements and intended for connection to the cold water supply only; · 1 5 °C ± 5 °C for other appliances. If the appliance does not incorporate a programmer, the water is heated to 90 °C ± 5 °C or as high as the construction will allow if lower, before starting the first washing period. The textile material consists of pre-washed double-hemmed cotton sheets having dimensions approximately 700 mm ´ 700 mm and a specific mass between 1 40 g/m 2 and 1 75 g/m 2 in the dry condition. For impeller washing machines, if the textile material does not move properly during operation, · the quantity of textile material may be reduced until the maximum power input of the motor is attained; or · a textile material comprising pre-washed double-hemmed cotton sheets, having dimensions of approximately 900 mm ´ 900 mm and a mass between 90 g/m 2 and 1 1 0 g/m 2 in the dry condition, may be used. However, for impeller washing machines, in case of doubt, the test is carried out using the reduced quantity of textile material.A steam generator intended to be filled by hand is filled according to the instructions, water being added to maintain the steam generation. A steam generator intended to be filled automatically is connected to the water mains. 3.5 Definitions relating to types of appliances 3.5.1 01 agitator washing machine washing machine in which the textiles are substantially immersed in the washing water, the mechanical action being produced by a device moving about or along its vertical axis with a reciprocating motion (an agitator) Note 1 to entry: This device usually extends above the maximum water level. 3.5.1 02 impeller washing machine washing machine in which the textiles are substantially immersed in the washing water, the mechanical action being produced by a device rotating about its axis continuously or which reverses after a number of revolutions (an impeller) Note 1 to entry: The uppermost point of this device is substantially below the minimum water level. 3.5.1 03 drum washing machine washing machine in which the textiles are placed in either a horizontal drum or a drum that is inclined up to and including 45° from the horizontal and the textile is partially immersed in the washing water, the mechanical action being produced by rotation of the drum about its axis, the movement being either continuous or periodically reversed 3.6 Definitions relating to parts of an appliance 3.6.1 01 steam generator device in which steam is produced at a pressure not exceeding 50 kPa and in which the pressure drops to atmospheric pressure when the steam is not supplied
1 1 Heating
This clause of Part 1 is applicable except as follows. 1 1 .3 Addition: Where the external accessible surfaces are suitably flat and access permits, then the test probe of Figure 101 may be used to measure the temperature rises of external accessible surfaces specified in Table 101. The probe is applied with a force of 4 N ± 1 N to the surface in such a way that the best possible contact between the probe and the surface is ensured. The measurement is performed after a contact period of 30 s. The probe may be held in place using a laboratory stand clamp or similar device. Any measuring instrument giving the same results as the probe may be used. 1 1 .7 Replacement: Appliances incorporating a programmer are operated for three cycles with the programme that results in highest temperature rises, with a rest period of 4 min between cycles.
