f) any operating details not specified in the method, as well as any incidents likely to have affected the results, such as. for example. phase separation, etc:
g) dateofthetest.
8 Method 2: Use of a plug former
8.1 PrincIple
The adhesive s used to nil a cavity of known dimensions. The adhesive plug is then extruded and the apparatus is placed vertically in the test atmosphere for the specified time and the degree of sagging measured.
8.2 Supplementary information
This method of test requires that the following supplementary Information shall be specified when the method is called up:
a) details of the test atmosphere;
b) details of the conditioning atmosphere:
c) temperature;
d) method of mixing of two-oomponent adhesives and the time between mixing and application:
e) duration of the test.
8.3 Apparatus and materials
8.3.1 Flow test apparatus. Block of metal, e.g. brass, light aloy or steel with a bright finish and overall dimensions not less than 10O 50) mm
The upper part of the block is drilled to provide a cylindrical cavity of diameter (38 ± 0.05) mm. The adhesive plug is extruded from the cavity by a solid plunger closely fitting the cavity and provided with means of positioning the face of the plunger flush with the face of the block and at a depth of (9,5 ± 0,05) mm. A graduated scale shall be marked or engraved on the lower face of the block. The first line shall be tangential to the lowest point of the circumference of the cavity and subsequent lines shall be spaced at (1 t 0,1) mm or (2 ± 0,1) mm intervals over a distance of 50 mm. A suitable design Is shown in Figure 3 wIth end plates fitted to support the block dunng filling.
