BS EN 14187-2:2017EN 14187-2:2017 (E) 4 1 Scope This European Standard describes a test method fo
20、r determining the tack free time of the cold applied joint sealant for use in joints in roads, air fields and other trafficked areas. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated
21、references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN ISO 6927, Buildings and civil engineering works - Sealants - Vocabulary (ISO 6927) 3 Terms and definitions For the purposes of this document, the t
22、erms and definitions given in EN ISO 6927 apply. 4 Principle The tack free time of a cold applied joint sealant is determined as the time when no sealant is adhering on a peeled off polyethylene film. 5 Apparatus 5.1 Flat bladed mixing spatula. 5.2 Metal or polyethylene frame, measuring internally (
23、125 5) mm long, (38 2) mm wide and (6,0 0,5) mm deep. 5.3 Metal base plate, measuring (150 5) mm long, (75 5) mm wide and (2,0 0,5) mm thick. 5.4 Polyethylene film, measuring (150 5) mm long, (20 2) mm wide and (100 10) m thick. 5.5 A metal plate, measuring (40 1) mm long, (30 1) mm wide and weighin
24、g (30,0 0,5) g. 5.6 Stop watch with a scale-reading precision of at least 1 s. 6 Conditioning Store supplies of the sealant samples in the closed containers for 16 h to 24 h at (23 2) C. 7 Procedure 7.1 For multi-component cold applied joint sealants, thoroughly mix appropriate quantities of base co
25、mponent with curing agent following the manufacturers instruction. One-component sealants can be applied directly from the pack. 7.2 Pour or fill in the cold applied joint sealant into the metal or polyethylene frame (5.2) mounted on its metal base plate (5.3) and strike off level with the flat blad
26、ed mixing spatula. 7.3 Transfer the test specimen into standard conditions at (23 2) C and (50 5) % r. h. and leave it for the tested period of time. BS EN 14187-2:2017EN 14187-2:2017 (E) 5 7.4 At the end of the tested period of time place the polyethylene film (5.4) on the upper surface of the spec
27、imen and immediately cover it with the metal plate (5.5). 7.5 Remove the metal plate after (30 3) s, then peel off the polyethylene film uniformly and constantly at a right angle to the surface of the sealant. 7.6 Examine the polyethylene film for signs of adhesion of the cold applied joint sealant
28、as long as material is picked up. When no material is adhering to the polyethylene film record the tack free time of the cold applied joint sealant. 8 Test report The test report shall include the following information: a) reference to this European Standard; b) name and type of the cold applied joi
29、nt sealant; c) batch of sealant from which the test specimens were produced; d) tack free time of the cold applied joint sealant; e) any deviations from the specified test conditions; f) date of test.
