The time between successive cone penetration should be not greater than 1/20 of the utilization time. The cone shall be cleaned and dried between each penetration and there should be at least 12 mm between each penetration mark. The time at which the depth of penetration achieved (35 ± 2) mm above the glass plate shall be noted t1. kSIST FprEN 14496:2016



FprEN 14496:2016 (E) 7 5.5.4 Expression of results The end of utilization time t is given by the following formula: ()8,001×−=ttt where t1 is the time at which the depth of penetration (35 ± 2) mm above the glass plate is achieved, in minutes t0 is the time at which the adhesive is first added to the water, in minutes 5.6 Determination of the bond strength 5.6.1 Principle The bond strength of an adhesive pad shall be measured by applying a force perpendicularly to the adhesion interface. NOTE Polystyrene is used as background as a typical insulating product. 5.6.2 Apparatus a) Two blocks (gauges) 20 mm thickness, 200 mm length, 20 mm width; b) five supports (racks) (150 × 150 × 60) mm (see Figure 1); c) a non absorbent plate (e.g. PVC…); d) five pieces of expanded moulded polystyrene (100 × 100 × 40) mm without surface treatment or cut expanded polystyrene with similar surface (cohesion
0,14 MPa). Five pieces are required for each adhesive tested; e) a taping knife (width
150 mm); f) bowl, balance, stirrer, etc. for gauging; g) a ventilated oven at (40 ± 2) °C; h) five metal plates (100 × 100 × 10) mm; i) double face adhesive tape (adhesion
0,15 MPa); j) hot-melt adhesive (adhesion
0,15 MPa); k) a dynamometer or an appropriate device to apply a convenient tensile force permitting readings to 10 N and having a self-centring clamp (see Figure 2); l) testing plate. kSIST FprEN 14496:2016
