3 Principle
Resistance of the coating system to severe chemical attack is assessed by exposing one side of the surface
protection system to the testing liquid.
4 Apparatus
4.1 Laboratory maintained at the temperature of (21 ± 2) °C and the relative humidity of (60 ± 10) %.
4.2 Usual accessories to apply the surface protection system to the basic test pieces.
4.3 Concrete slabs as basic test pieces, according to EN 1766.
4.4 Test apparatus
The test apparatus consists of a metal frame to take up the test piece and to clamp one or two bell-type caisson chambers (see Figure 1) The bell-type caisson chamber consists of a bell-type steel cup with an inner diameter of> 100 mm. (The tested area is a circle with a diameter of 100 mm inside of the glued rings). It is connected to a compressed air vessel equipped with a pressure reducing valve via a compressed air hose. The pressure device is fixed on the surface protection system by a metal clamp. To ensure the tightness of the caisson chamber, a rubber cuff is placed between the surface protection system and the caisson chamber.
5 Sampling
A representative and homogenous sample of the material under test shall be taken as described in EN ISO 15528.
The sample shall be examined and prepared as described in EN ISO 1513.
6 Test method
6.1 Test pieces
Test pieces are concrete slabs measuring at least 300 mm x 200 mm x 40 mm ana are tabricatea in accordance with EN 1766 using a test concrete (C (0.45) with a maximum aggregate size of 8 mm.
Concrete slabs are prepared and stored according to EN 1766. Surface preparation is carried out according to EN 1766 by grit-blasting. Alter storage, according to EN 1766. the concrete slabs shall be stored for at least 7 days in a climate of (21 ± 2) °C / (60 ± 10) % R. H. before they are coated.
The test pieces are coated, cured and stored in accordance with the manufacturer’s instructions, The coating
thickness is to be measured in accordance with EN ISO 2808.
NOTE
It is possible to use slabs without any reinforcement.
It is also possible to use slabs with a reinforcement cage according to prEN 1062-7:2002, Informative annex C,
C.2.2.3. Then, after a crack-bridging test, the test of resistance against severe chemical attack can follow immediately with the same test pieces.
When the resistance of the coating above the crack in the concrete is to be tested. only one bell-type caisson chamber is used. It is positioned exactly above the notch in the slab.BS/EN 13529-2003 pdf download.
