Multilayer board shall be tested as a whole From the sample cut stripes to an amount of test pieces sufficient to give dm² of paper or board for each flask Minimum size of the stripes is cm x cm Mention the size in the test report 10 Procedure Introduce the test pieces (6 dm²) loosely into the flat bottom flasks (7.2) Ensure that the surfaces of the test pieces are freely exposed Close the flat bottom flasks and keep them for 20 h to 24 h at (23 ± 2) °C in the dark 11 Evaluation of the test Give each assessor her/his own coded flasks in a randomized order, a known empty flask (zero odour) and an evaluation form NOTE A computerised data collection system may be used for the evaluation The assessor shakes the flask, opens it and sniffs the contents immediately after opening the vessel If a repetition is necessary, the vessel shall be kept closed for at least The assessor records the intensity of the perceived odour on the evaluation form as follows: a) = no perceptible odour; b) = odour just perceptible (difficult to define); c) = weak odour; d) = clear odour; e) = strong odour Though the steps of the scale uses only whole numbers, the assessors may use half number ratings if considered necessary Starting with intensity 2, a description of the odour may be given NOTE Due to the sensory fatigue it is recommended that not more than five tests are performed in succession In order to avoid adaptation effects, it is recommended that the assessors pause for to between each test 12 Expression of results 12.1 Calculation Calculate the median of all the individual scores Copyright British Standards Institution Provided by IHS under license with BSI -
