BS/EN 16382-2016 pdf download.Thermal insulation products for building applications Determination of the pullthrough resistance of plate anchors through thermal insulation products.
d5 is the diameter of the circular recess in the template in mm;
d is the diameter of the anchor plate including additional plates if used in mm;
ti is the thickness of the thermal insulation product in mm.
5.3 Clamping device
At least two clamps (7) at each edge are used to fix the thermal insulation product.
5.4 Tension plate
The circular tension plate (5) introduces the load into the thermal insulation product. The tension plate shall be rigid. It shall be connected to the testing machine by a self-alignment device in the centre. The tension plate shall have a diameter of d = d5 — 10 mm.
NOTE Suitable materials for the tension plate are e.g. laminated wood plates of at least 20 mm thickness or steel plates of at least 7 mm thickness.
5.5 Tensile testing machine
The tensile testing machine needs to be appropriate for the range of force and the displacement involved and capable of having a constant crosshead speed adjusted to (20 ± 1) mm/mm. It shall be capable of measuring the force with an error limit of a maximum of I % (see EN 1607).
The tensile testing machine shall be capable of continuous recording of load and displacement in order to report load/displacement graphs for all test specimens.
6 Test specimens
6.1 Thermal insulation product and anchor position
The specimen of the thermal insulation product shall be at least as large as the outer dimensions of the template described in 5.2.
To determine the pull-through resistance in the middle area position a specimen without a joint shall be used as shown in Figure 4, a). If the insulation board is smaller than the side length b of the template, the tests shall be performed as shown in Figure 4, c).
To determine the pull-through resistance in joint position a T-joint between three insulation boards is used. The specimen shall he arranged as shown in Figure 4, b).
To determine the pull-through resistance in the edge/corner position a specimen with three insulation boards shall be used as shown in Figure 4, d).
6.2 Preparation of the test specimens
The plate anchor shall be placed according 6.1. In case of test setups according Figure 4, b), c) and d), the insulation boards shall be secured together on the edges with a suitable circumferential adhesive tape, to counter a movement of the boards in horizontal direction.
lithe anchor Is fixed in a concrete slab, a concrete slab with a minimum strength corresponding to class C20/25 according to EN 206 shall be used (see Figure 6). The spacer to the thermal insulation product shall be equivalent to the thickness of the lower template plus the clamps. The anchor shall be installed following the manufacturer’s instructions. Size and thickness of the concrete slab shall correspond to the embedment requirements of the anchor.
To locate the position of the tension plate, place the template on the insulation board and mark the position of the circular recess. The tension plate shall be fixed in the marked position with a suitable glue. The tension plate shall not touch the edges of the upper template and shall be separated from the anchor plate by using a suitable non-adhesive foil.
Anchors with additional plates to increase the plate diameter shall be fully covered with a non-adhesive foil.
After curing of the glue the specimen shall be clamped between the templates without compressing the thermal insulation product.
The specimen shall be conditioned at (23 ± 3) °C and (SO ± 10) % relative humidity for at minimum 24 h.
6.3 Number of test specimens
For the determination of the characteristic pull-through strength at least 5 test specimens are required. NOTE MinImum 5 valId measurements are needed for the statistic evaluation.BS/EN 16382-2016 pdf download.
