20、2003 (E)5Dimensions in millimetresFigure 1 Funnel and collection cylinder7 SamplingTake a representative sample of the adhesive to be tested in accordance with EN 1066 and examine and prepare itfor testing as described in EN 10678 Procedure8.1 Determine the mass (m1) of the empty container (6.3).8.2

21、 Condition the sample for at least 12 h at (23 2) C and (50 5) % relative humidity.8.3 Pour (115 5) cm3 of sample into the funnel (6.4) positioned coaxially over the cylindrical container at (114 +38) mm height from the top (see Figure 1), taking care that the lower orifice is closed by a suitable c

22、losure.NOTE Any rigid sheet larger than the orifice is suitable.EN 543:2003 (E)68.4 Open the orifice and allow the material to flow into the cylindrical container. If the flow stops or becomesinconveniently slow, it can be speeded up by gently prodding the material in the funnel with a wire.Avoid co

23、mpressing the material or shaking the container.8.5 When the container is full, remove excess product by levelling off at the upper edge with a flat spatula.Avoid compressing the material or shaking the container.8.6 Determine the mass (m2) of the full collection container.9 Expression of resultsThe

24、 apparent density (in gram per cubic centimetre) is given by the following equation:r=whereris the apparent density in gram per cubic centimetre of the adhesive;m2is the mass (in gram) of the full container;m1is the mass (in gram) of the empty container.The reproducibility and the repeatability of t
