Close and leave for 1h.4.4.3.2 Attach one end of the canvas strap to the handle of the container. Attach the other endof the canvas strap to the inelastic support. A
42、llow the container to fall freely before beinginstantly arrested by means of a positive stop incorporated into the inelastic support.4.4.3.3 Raise the container vertically through 100 mm causing the canvas strap to becomeslack. Release the container and allow it to fall freely such that its fall is
43、instantly arrested bythe canvas strap acting on the handles.BS EN 12546-2:2000Page 8EN 12546-2:20004.4.3.4 Repeat the procedure for a total of 10 falls.4.5 Seepage test4.5.1 PrincipleColoured water containing a wetting agent is introduced into the container under test which isshaken in order to wet
44、all the internal surfaces. The container is dismantled to assess seepageof the coloured water from the inner container to the insulant.4.5.2 Apparatus4.5.2.1 Coloured water containing 1,0 gram per litre wetting agent and a small quantity ofintensely coloured non-colour fast water soluble dye.NOTE 1:
45、 Domestic washing up liquid is suitable for the wetting agent.NOTE 2: Fluorescein is suitable for the dye. For ease of determination of results,a colour which contrasts with that of the construction of the container under testshould be chosen.4.5.3 Procedure4.5.3.1 Place into the container under tes
46、t a quantity of coloured water approximately equal to25% of its nominal capacity. Close the container.4.5.3.2 Shake the container up and down through a distance of (200 50) mm, 25 times in(15 1) s.4.5.3.3 Empty the container. Dry all exposed surfaces. If the container under test is a bagwhich is cla
47、imed to be washable follow the washing instructions to wash the bag and allow todry thoroughly.4.5.3.4 Dismantle or cut apart the container to reveal the insulant and examine the insulantbetween the inner container and the outer protective case to assess any seepage into theinsulant.5 Marking and la
