24、ilar use. The purpose of this standard is to state and define the main performance characteristics for toasters, which are of interest to the user, to describe the standard methods for measuring these characteristics and to give some guidelines for the evaluation of test results. Taking into account

25、 the low grade of accuracy and repeatability, due to variations in time and origin of test materials and ingredients and to the influence of the subjective judgement of test operators, the described test methods may be applied more reliably for comparative testing of a number of appliances at approx

26、imately the same time, in the same laboratory, by the same operator and with the same utensils, rather than for testing of single appliances in different laboratories. This standard is not concerned with safety. It does not apply to appliances designed exclusively for commercial or industrial use. 2

27、 Normative reference The following normative document contains provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publication, the edition indicated was valid. All normative documents are subject to revision, and parties to agreemen

28、ts based on this International Standard are encouraged to investigate the possibility of applying the most recent edition of the normative document indicated below. Members of IEC and ISO maintain registers of currently valid International Standards. BS 3999, “Shade chart” Part 5 C. 1983. 3 Definiti

29、ons For the purpose of this International Standard the following definitions apply. 3.1 radiant toaster toaster intended for toasting slices of bread by radiant heat. The slices are toasted either on one side or both sides at a time NOTE Radiant toasters may be provided with attachments for heating

30、rolls and for toasting sandwiches. 3.2 contact (horizontal) toaster toaster with one or more heating surfaces which can be brought into contact with slices of bread NOTE Contact (horizontal) toasters are intended for toasting only on one side at a time. Some contact toasters heat both sides at the s

31、ame time, particularly when toasting sandwiches. 3.3 roll heating device device for holding rolls to be heated on the toaster NOTE This device can be built in or supplied with the toaster. 3.4 toasting control device device that automatically terminates the toasting process 3.5 bread carriage the pa

32、rt of the toaster that supports the bread and releases it at the end of the toasting process 3.6 browning control range a certain setting on a scale that can be marked with number, symbols or shades of colourEN 60442:1998 4 BSI 5 September 2003 3.7 toasting chamber space intended for the loading of

33、the slices of bread 3.8 evenness of browning the brownness visually determined and averaged over one surface of the toasted slice of bread in each individual case 3.9 toasting degree average brownness reached by the slices of bread at the end of the toasting process 3.10 toasting range range of the

34、toasting degree from the minimum brownness to the maximum brownness 4 General conditions for measurements Unless otherwise specified, the measurements shall be made under the following conditions: Ambient temperature: 20 C 5 C. Electrical supply: the measurements shall be made at rated frequency and

35、 at a voltage which is within 0,5 % of the rated voltage or the mean of the rated voltage range. NOTE If the rated voltage differs from the nominal supply voltage of the country concerned, measurements carried out at rated voltage may be misleading. Therefore, for comparative testing the voltage use

36、d for the tests should conform to the nominal supply voltage and this should be reported. Testing room: substantially draught free. Placing of the appliances: at a distance of a least 30 cm away from walls, on a dull black painted wooden support. Unless otherwise specified, toasters with roll heatin

37、g device or sandwiches device are tested without such devices. 5 Overall dimensions The overall dimensions of the appliance (length, height and width, doors, if any, closed, including any controls, handles or other protrusions) shall be measured and the dimensions shall be indicated in millimetres.

38、6 Length of the flexible cord The length between the point of entry of the cord to the toaster and the entry point in the plug, including any cord guard, shall be measured and indicated in metres, to the nearest 0,05 m. The existence of a cord storage device or a cord chamber for the supply cord sha

39、ll be stated. 7 Mass of the appliance The mass of the toaster, without accessories and with flexible cord and plug if attached, is determined and indicated in kilograms, to the nearest 0,1 kg. 8 Number and dimensions of the toasting chambers (radiant toasters), toasting surfaces (contact toasters) T

40、he number of the toasting chambers into which the bread slices can be placed to be toasted on both sides at a time, or of the toasting surfaces on which the bread slices are put to be toasted on one side at a time, shall be determined and indicated.EN 60442:1998 BSI 5 September 2003 5 For each toast

41、ing chamber or toasting surface, the dimensions (length, height, width) which are applicable, shall be determined and indicated in millimetres. In case of variable toasting chambers and toasting surfaces, the maximum useable dimensions are given. The dimensions of the largest slice of bread, having

42、a thickness of 12 mm, which can be inserted into the toasting chamber without force or which can be placed on the toasting surface, shall be determined and indicated in millimetres. The number of standard bread slices having dimensions of 100 mm 100 mm 12 mm which can be toasted at one time, on both

43、 sides or on one side only, shall be determined and indicated. 9 Force necessary to operate the bread carriage The force necessary to operate the bread carriage to start the toasting process shall be measured (e.g. by using a spring balance) and indicated, rounded off to the nearest newton. 10 Bread

44、 to be used for the tests on toasters The measurements according to Clauses 11 to 14 are made with factory-made white bread common in the relevant country, but care has to be taken that, if more than one loaf is necessary, bread from the same batch is used and treated the same way. The dimensions of

45、 the bread shall be 100 mm 100 mm 12 mm 1 mm. The bread is put into suitable plastic bags and stored in a draught-free room, away from direct sunlight at an ambient temperature of 20 C 2 C. The end slices of each loaf are discarded. NOTE The storage in plastic bags is necessary to avoid moisture los

46、s, since the duration of the test is considerably longer than normal toasting time. For all the following tests, the bread slices are used with crusts. 11 Browning control setting These tests have to be carried out with minimum and maximum load as indicated in the manufacturers instructions. 11.1 Br

47、owning control setting for bread The browning control is set to a medium position or to the position for medium brownness (golden brown) declared by the manufacturer. Starting from “cold” with the toaster fully loaded, two toasting cycles are made, with an interval of 15 s or longer if recommended b

48、y the manufacturer. If the result of “golden brown” is not reached, the appliance is cooled down completely and two further cycles are made with an appropriate corrected setting. 11.2 Browning control setting for sandwiches The same procedure of 11.1 is applied, but the toaster is loaded with sandwi

49、ches made with two slices of bread filled with one slice of appropriate cheese, having approximately an area equal to one slice of bread and a thickness of approximately 5 mm. NOTE Processed cheese and other cheese which readily melts on heating (such as sliced cheese with a fat content of 75 % 5% o r Emmenthal cheese) are suitable, but care has to be taken that the same cheese of the same batch of production is used for one complete test.
