Measurement 1)oillts shall be marked at the middle of each surface of test piece. The centre pointS shall be marked on both fces of tangential and radial stirfces for determi iii ng the (Ii menSion in radial and tangential directions, respectively. Dimensions of the test pieces shall be measured between the marks at each stage of moisture conditions.
5.3 Procedure
5.3.1 Determination of the dimensions of test pieces in green or fully saturated condition
The moisture content of test pieces shall be considerably higher than the fibre saturation point (FSP). When the moisture content is belov FSP, soak the test pieces in distilled water at a temperature of (20 ± 2) °C until no further change in dimensions occurs. Check the changes in dimensions every 3 d through repeated measurements at the same points until the difference between two successive measurements does not exceed 0,01 mm. In this case, it shall be reported that the results arc obtained on test pieces which have been previously soaked. Measure the radial and tangential dimensions, l and I, of each test piece to an accuracy of 0,02 mm.
5.3.2 Determination of the dimensions of test pieces at absolutely dry (oven-dry) condition
After air-seasoning, the test pieces shall be open-piled and dried to constant weight at a temperature of (103 ± 2) °C in the oven, ensuring no checks distorting their dimensions and shape occur. Check the changes in weights of’ two or three control test pieces after 8 h of (frying and repeat the measurements every 8 h or longer until the difference between two successive weighing does not exceed 0,2 % of the test pieces or when the difference between two successive measurements does not exceed 0,02 mm of the corresponding dimension of the test piece. Test pieces in which checks occurred during the test period shall be disregarded. Cool the test pieces to room temperature in the desiccator. Measure the radial and tangential dimensions, Ii-2, and It2 of each test piece to an accuracy of’ 0,02 mm.ISO 13061-14:2016 pdf free download.
