IEC 61855:2003 pdf – Household electrical hair care appliances – Methods of measuring the performance.
1 Scope This International Standard applies to electrical 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 comparable 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 environmental 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 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

3.2 hairstyling appliance with warm air hairstyling appliance in which a stream of warm air is produced for drying and styling the hair 3.3 curling appliance appliance in which heat is produced for styling dry hair. NOTE The hair may contain a small quantity of residual moisture. 3.4 curling set set of rollers that can be heated for styling hair. 3.5 concentrator accessory for directing the air flow. 3.6 diffuser accessory providing a wide distribution of the airflow. NOTE For the purposes of this standard, a volumiser is considered to be a diffuser. 3.7 rated voltage voltage assigned to the appliance by the manufacturer. 3.8 rated frequency frequency assigned to the appliance by the manufacturer. 4 List of measurements and tests 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 hairdryers 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 clause 7; − drop test according to 6.9.
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 according 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 specified 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 hairstyling appliances with warm air, steady conditions are considered to be established 10 min after switching on the appliance.
