19、isture contentloss of mass of a test specimen after drying under specific conditions, compared to the initial mass of the test specimen4 PrincipleDetermination of the mass of a test specimen, drying and re-determination of its mass, then calculation of the loss of mass in percentage, referred to the

20、 initial one.5 ApparatusOrdinary laboratory equipment and, in particular, the following.5.1 Balance, with a resolution of at least 0,5 g.5.2 Drying oven, ventilated, and set at (103 2) C.5.3 Open containers (dried), of adequate capacity to hold the test specimens.To dry the containers, place them in

21、 the oven at (103 2) C for 30 min. After that, let them cool during 30 min in the desiccator.5.4 Desiccators, of adequate capacity to hold the containers, and containing an efficient desiccant (e.g. silica gel or calcium chloride).

22、edure6.1 Test sampleFrom the laboratory sample, take at random three test specimens of mass about 400 g each.6.2 DeterminationDetermine the mass of each container (m1).Place each test specimen in a container and determine the mass of each set (m2).Put the sets in the oven (5.2) set at (103 2) C, for

23、 at least 1 h. Then place them in the desiccator (5.4) and let them cool for at least 30 min. Then determine the mass of each set.Repeat the procedure described above until constant mass (i.e. until two consecutive weighings of each set do not differ by more than 0,5 g) (m3).To accelerate the test,

24、it is advisable that the first drying lasts for at least 3 h.7 Results7.1 CalculationThe moisture content of each test specimen, referred to the initial mass (before drying) and expressed as a percentage is given by the formula:mmmm2321100wherem1is the mass of the container, in grams rounded off to

25、the nearest 0,5;m2is the mass of the container and test specimen (set) before drying, in grams rounded off to the nearest 0,5;m3is the mass of the container and test specimen (set) after drying, in grams rounded off to the nearest 0,5.7.2 Expression of resultsTake as the moisture content of the lot

26、of corkwood, the average, rounded off to the nearest integer, of the results obtained for each test specimen.8 Test reportThe test report shall include the following particulars:a) all details required to identify the sample;b) the result obtained, in accordance with Clause 7;c) reference to this In
