21、Test equipment for measuring the drying rate 18 Page3 EN61855:2003 INTRODUCTION This standard does not deal with hair care appliances with radiant heating or with helmet dryers (see Scope) for the following reasons: the test methods are likely to be complicated and expensive and they might not be su
22、fficiently repeatable; suitable and or proven test methods are not known at present; developing of test methods for these appliances will incur considerable costs; the market shares of these appliances are rather small. National Committees who consider that hair care appliances with radiant heating
23、and helmet dryers should be included into maintainance activities are requested to submit proposals suitable for the corresponding test method. Page4 EN61855:2003 HOUSEHOLD ELECTRICAL HAIR CARE APPLIANCES METHODS FOR MEASURING THE PERFORMANCE 1 Scope This International Standard applies to electrical
24、 appliances for household and similar use for drying and styling hair (including their accessories). This standard defines the main performance characteristics that are of interest to the user and specifies methods of measuring these characteristics. The measuring procedures are developed for compar
25、able tests. This standard does not specify requirements for performance. This standard does not cover hair care appliances with radiant heating, helmet-type dryers or cutting devices. NOTE 1 This standard does not deal with safety requirements (IEC 60335-2-23). NOTE 2 Due to the influence of environ
26、mental conditions, variations in time, origin of test materials and proficiency of the operator, most of the described test methods will give more reliable results when applied for comparative testing of a number of appliances at the same time, in the same laboratory and by the same operator. 2 Norm

33、sts Depending on the appliance, the following measurements or tests shall be carried out, as appropriate: mass, according to 6.1; length of the flexible cord, according to 6.2; power input, according to 6.3; heating-up time, according to 6.4; temperatures, according to 6.5; air flow of hand-held hai
34、rdryers and hairstyling appliances with warm air, according to 6.6; drying rate, according to 6.7; attachment of accessories, according to 6.8; ease of handling, according to 6.8.2; features, according to clause 8; instructions for use, according to clause 9; airborne acoustical noise, according to
35、clause 7; drop test according to 6.9. Page6 EN61855:2003 5 General conditions for measurements Unless otherwise specified, the tests are carried out under the conditions of 5.1 to 5.5. 5.1 General The measurements are made with controls adjusted to their highest setting and when steady conditions ac
36、cording to 5.4 are established. 5.2 Test room The tests are carried out in a substantially draught-free room. The ambient temperature is maintained at (23 2) C. 5.3 Power supply The tests are carried out at the rated voltage 1 % and the rated frequency 1 %. If a voltage or a frequency range is speci
37、fied by the manufacturer the appliance is to be supplied at the nominal voltage and at the nominal frequency of the country in which the appliance is intended to be used. In this case the test voltage and frequency shall be stated in the report. 5.4 Steady conditions For hand-held hairdryers and hai
38、rstyling appliances with warm air, steady conditions are considered to be established 10 min after switching on the appliance. For other appliances steady conditions are considered to be established 20 min after switching on the appliance or when the thermostat has operated four times, if this occur
39、s first. 5.5 Thermocouples The thermocouples shall: be of class 1 according to IEC 60584-2; be accurate to 1,5 K; have a nominal diameter of 0,25 mm. 6 Measurements 6.1 Mass of the appliance The mass of the appliance is determined including the flexible cord but excluding any accessory. The mass of
40、each accessory is measured separately. The results are expressed in kg to the nearest 0,01 kg. Page7 EN61855:2003 6.2 Length of the flexible cord The length of the flexible cord is measured between the point where the cord or cord guard enters the appliance and the cord entry point of the plug. Coil
41、ed cords are stretched with a pull of 10 N before measurement. The length is expressed in metres rounded down to the nearest 0,05 m. IEC 61254, 5.3, modified 6.3 Power input The power input of the appliance is measured at rated voltage without any accessory, in accordance with 5.3. The accuracy of p
42、ower-measurement is to be within 1 %. The power input is expressed in watts, rounded off to the nearest integer. 6.4 Heating-up times 6.4.1 Hand-held hairdryers Not applicable. 6.4.2 Curling appliances The heating up time of curling appliances is the time taken for the temperature rise of the barrel
43、 to reach 100 K, measured in accordance with 6.5.3.1. The time is expressed in minutes and seconds. NOTE This temperature rise implies a temperature of approximately 120 C which is considered to be the minimum temperature necessary for styling of dry hair. 6.4.3 Curling set Under consideration. 6.4.
44、4 Other hair styling appliances Under consideration. 6.5 Temperatures 6.5.1 General The test methods are only applicable for comparative testing, except for the tests according to 6.5.2 and 6.5.3.1, which are considered to be reproducible. 6.5.2 Outlet air temperature of hand-held hairdryers Control
45、s are adjusted to obtain the highest outlet air temperature measured using the device as described in Figures 2 and 3. The temperature is measured within 30 s after steady conditions have been reached, in accordance with 5.4. The measured outlet air temperature T iof each measurement is the mean val
46、ue of the five measuring points with the highest values and is expressed in C, rounded off to one decimal place. The accuracy of measurement is to be within 3 K. Page8 EN61855:2003 In order to compensate the variation of the ambient temperature the measured outlet air temperature T i has to be corre
47、cted according to formula (1): C 23 amb act comp , + = T T T i i(1) where T i,compis the compensated outlet air temperature; T act ambis the actual ambient temperature measured 100 mm from the air inlet side of the appliance immediately before switching it on; 23 is the nominal ambient temperature i
48、n C. The distance between the device and the the air outlet is: without attachments: 25 and 100 mm, as shown in Figure 4a; with a concentrator: 100 mm, as shown in Figure 4b; with a diffuser: 50 mm, as shown in Figure 4c. The measurement without attachments has to be carried out three times. The mea
49、n value out of these three measurements is the final outlet temperature and is calculated from formula (2): C 3 comp 3, comp 2, comp 1, fin + + = T T T T (2) NOTE Three measurements are needed to achieve a sufficient reproducability of the drying rate. The test can be repeated with the control adjusted to lower settings, if any, except for supplying cold air
