17、European Standard has been prepared by the Technical Committee CEN/TC 193, Adhesives, the secretariat of which is held by AFNOR. The European Standard shall be given the status of a National Standard, either by publication of an identical text or by endorsement, at the latest by May 1995, and confli
18、cting national standards shall be withdrawn at the latest by May 1995. According to CEN/CENELEC Internal Regulations, the following countries are bound to implement this European Standard: Austria, Belgium, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands,

20、anule adhesives. The method is applicable to all powder and granule adhesives. 2 Normative references This European Standard incorporates by dated or undated references, provisions from other publications. These normative references are cited at the appropriate places in the text and the publication
21、s are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies. EN 1066, Adhesives
22、 Sampling1). EN 1067, Adhesives Examination and preparation of samples for testing1). 3 Principle The method is based on the determination of the mass of a known volume of powder or granule adhesive and is performed at a temperature of (23 2) C, relative humidity (50 5) %. 4 Apparatus Usual laborato
23、ry apparatus including the following: 4.1 Balance, accurate to 0,1 g. 4.2 Cylindrical container, capacity (100 0,5) cm3, internal diameter of (40 2) mm. 4.3 Funnel, as shown in Figure 1. 4.4 Spatula 5 Sampling Sample as described in EN 1066. Homogenize as described in EN 1067. 6 Procedure 6.1 Determ
24、ine the mass m1 of the empty container (4.2). 6.2 Condition the sample for at least 12 h at (23 2) C and (50 5) % relative humidity. 6.3 Pour 110 cm3 to 120 cm3 of sample into the funnel positioned coaxially over the collection cylinder at a height of (114 + 38) mm from the top (see Figure 1), takin
25、g care that the lower orifice is closed by a suitable closure. (See note.) NOTEAny rigid sheet larger than the orifice is suitable. 6.4 Open the orifice and allow the material to flow into collection cylinder. If the flow stops or becomes inconveniently slow, it can be speeded up by gently prodding
26、the material in the funnel with a wire. Avoid compressing the material or shaking the cylinder. 6.5 When the cylinder is full, remove excess product by levelling off at the upper edge with a flat spatula. 1) In course of preparation.
