For a material with a wo

Prepare test pieces from complete upper assemblies when the lining material is permanently attached to the upper material. 5.1.3 For test specimens cut from footwear uppers avoid any areas containing seams

NOTE It may not be possible to cut a test specimen of sufficient size from certain types of footwear, especially childrens, and the test specimen size shou

Air of specified humid
46、ity and temperature is blown over the test specimen at a set velocity. The air within the pot is circulated by moving the pot which agitates the desiccant. After a measured time the mass of water vapour transmitted through the test specimen is determined and the water vapour permeability of the mate
47、rial calculated. 6.1.2 Procedure 6.1.2.1 Pour freshly dried silica gel (see 4.1.4) into one of the pots (see 4.1 .I) until it is half full. 6.1.2.2 Place a test specimen centrally over the open end of the pot prepared in 6.1.2.1 so that the surface which would be closer to the source of water vapour
48、 in the final product is uppermost. For example if assessing the perspiration transmission properties of a footwear upper material, then the surface which will be nearer to the foot s hou Id be uppermost. 6.1.2.3 the test specimen is securely held around its edges and the pot is sealed. Fit a clampi
49、ng ring (see 4.1 .I .2) centrally over the top of the test specimen and tighten the ring so that 6.1.2.4 Repeat the procedure in 6.1.2.1 to 6.1.2.3 for the remaining two test specimens. 8 EN 13515:2001 (E) 6.1.2.5 This is to condition the test specimens. Place each filled test pot onto the turntable (see 4.1.2.1) and operate the test machine for 20 h f 4 h. 6.1.2.6 Remove each of the test pots from the turntable. 6.1.2.7 For each test pot and as quickly as possible remove the clamping ring to release the test specimen, pour away the silica gel from inside the pot, refil
