4 Principle
This met hod is intemled to serve as an accelerated test for the assessment of damage to hot applied sealants resulting from fluctuating temperatures. water-spraying and simultaneous dynamic loads.
5 Apparatus
5.1 Tensile test rig, which allows the test Specimens to he inserted into holding clamps, conveniently and withotit disturbing tlw test specimens before, during or after removal. The test rig shall he capable of testing one specimen or a number of test specimens simultaneously and shall not be significantly affected by the failure of one or more test specimens.
The testing rig shall have the following characteristics:
be motor driven through positive drives without slip or signi t icant backlash, so hat cycles of extension and compression are carried out steadily and automatically;
— be capable of moving the test specimens smoothly and linearly, so that theiralignment is maintained at all times without subjecting them to torsion, betiding, shock, or significant vibration:
— under the Speci I ed conditions in Cbui H
— be capable of measuring and recording the changes in force;
— i’he accuracy of the test rig shall be class 2A according to ISO 5893.
Testing may also be carried out at differing rat os of teniperiture, delorination and movement en accordance with the sealant manufacturer’s recomnwndations provided that the criteria are within the capabilities of the test rig described above.
5.2 Climate chamber, capable of reducing or raising the temperature of a [LIII complement of test specimens to the specified temperature throughout the period of examination.
The chamber shall be fitted with a time controlled device to allow the specimen to he subjected to water spraying for 20 % of the total conditioning time at the appropriate temperature as provided for in Chiis 7,
5.3 Temperature indicator, consisting of an electronic device capable of measuring temperatures in the range of -30 °C to +30 °C to an accuracy oft 1 °C;
5.4 Depth gauge. device to measure depth of failures to the nearest I mm.
6 Preparation and conditioning of test specimens
6.1 Prepare the test specimens according to EN 11880-6.
6.2 Concrete test blocks in accordance with EN I3f181J-12 and aspnait test blocks in accoraance wirn EN 13880—11 shall be used. The dimensions of the test blocks arc (75 ± I ) mm length, (25,0 ± 0,5) mm width and (12,0 ± 0,5) mm Iwight. The concrete test blocks shall have a moisture content within the limits ol(5,5 ± 1.5) %.
6.3 Use a suitable mould to place two test blocks exactly opposite each other for a joint width of (12.0 * 0.5) mm.
6.4 If a primer is used, apply it to the sawn test faces of the test blocks in accordance with the manufacturer’s Instructions.
6.5 Place a top-mask on the mould so that the joint can be overtilled when the test sample is poured Into it.
6.6 Any adhering of the test sample to the borders of the joint shall he avoided.
6.7 Allow the test specimens to cool at laboratory temperature for 2 h after which remove the excess test sample using a heated knife so that the test specimens are flush with the surface of the test blocks.BS/EN 13880-7-2019 pdf download.
