EN 441-6, Refrigerated display cabinets Part 6: Classification according to temperatures. 3 Preparation and testing 3.1 Ambient temperature The ambient temperature shall be between + 22 C and
28、 + 30 C (for climate classes 2, 3 and 4 see EN 441-4, 4.1.7). 3.2 Cleaning The cabinet shall be cleaned prior to the test in accordance with the manufacturers instructions and afterwards with pure water. 3.3 Thermostat setting The cabinet shall be operated for 48 h, with the thermostat and other con
29、trol devices set in accordance with the manufacturers instructions which will give the required temperatures according to the relevant classification (see EN 441-6, clause 3). 3.4 Samples The analytical samples and check samples respectively for each cabinet or compartment are: a) 100 ml potable wat
30、er; b) a slice of fresh unsalted butter of 75 mm 35 mm 5 mm. From each of a) and b), six samples at least are necessary to serve as analytical samples and six at least to serve as check samples. The analytical samples shall be placed in Petri dishes and the check samples in glass containers, the lat
31、ter being hermetically sealed. Prior to the test all Petri dishes and containers which are used for the test shall be cleaned with fuming nitric acid and subsequently washed with distilled water until complete absence of odour is obtained. The analytical samples of water and butter shall be placed u
32、ncovered into the cabinet or compartment. The check samples in the hermetically sealed glass containers shall be placed close to the analytical samples. 3.5 Test period The analytical samples and the check samples shall be left in the operating cabinet with the door(s), if any, closed and at the spe
33、cified temperature conditions for 48 h. After 48 h, the analytical samples shall be covered. The analytical samples and check samples shall be removed and warmed to approximately 20 C by leaving them in the test room. 4 Examination of samples 4.1 Conditions Examination shall be made about 2 h after
34、removal of the samples from the cabinet and shall be carried out by at least three examiners familiar with the test method. Each examiner receives: two analytical samples of water; two check samples of water; two analytical samples of butter; two check samples of butter. The identity of the samples
35、shall not be made known to the examiners. The samples of water shall be examined prior to the samples of butter, unless a separate examination by different examiners takes place. The examiners shall record their remarks independently of each other, in writing. 4.2 Evaluation The evaluation of the an
36、alytical samples shall be carried out with reference to the following scale: Mark 0: no foreign odour or foreign taste; Mark 1: slight foreign odour or foreign taste; Mark 2: definitely perceptible foreign odour or foreign taste; Licensed Copy: sheffieldun sheffieldun, na, Sat Nov 04 09:36:16 GMT+00
