13、ication and requirements for pedestrian walkway sealants 1 Scope This International Standard applies to sealants used for pedestrian walkways, public areas, movement joints between concrete slabs, areas with pedestrian load, areas which are used with trolleys, parking garages, walkable floors, balco

14、nies, terraces, and warehouses. This International Standard specifies the types and classes of elastic sealants used in building construction pedestrian walkways according to their performance characteristics. Sealant may be either non-sag or self-leveling as declared by the manufacturer. Areas of a

15、pplication are floor joints which have been designed. Chemical containment, cold applied joint sealants for concrete pavements to be used in roads, airfields, and sewage treatment plants are excluded. Local regulations may be required in addition to this International Standard based on local laws an

If the measured secant tensile modulus value at 100% strain exceeds the values specified below for either or both temperatures, the sealant shall be classified as high modulus. Specified values (see Table 2 and Table 3)

24、 are as follows: 0,4 N/mm 2at + 23 C (1) 0,6 N/mm 2at 20 C (2) The secant modulus shall be the mean value of the three measured values. Round the mean value to one decimal place. EXAMPLE Measured values: 0,43 N/mm 2 , 0,40 N/mm 2 , and 0,46 N/mm 2 . Mean value: 0,43 N/mm 2 . Reported value: 0,4 N/mm

Exterior applications: code EXT XX (XX represents the number of movement cycles exhibiting no failure in a mechanical cycling during weathering). Interior applications: co

26、de INT. INT classified sealants are suitable for interior use only. EXT classified sealants are suitable for use in both interior and exterior applications. Interior class sealants are intended to be in conditioned spaces without direct UV exposure. 4.2.3 Sealants of class 12.5 are classified accord

37、or which details are given in the test methods and also noted in 6.1 and 6.2. For each test method, three test specimens for each substrate shall be tested (see also Clause 7). The same batch of sealant (and primer, if used) shall be used in all tests. The same mortar substrates, M1 or M2, shall be

38、used in all tests and as defined in ISO 13640. It should be noted that project specific testing for plazas and walkways that intend to use this criteria to determine the suitability for elastic sealants on natural stone substrates shall also include ISO 16938-1 and ISO 16938-2 to determine if a stai

39、ning potential exists. Testing is carried out on mortar, M1 or M2, according to ISO 13640 and primers are allowed and reported if used. NOTE Other substrates can be used if agreed amongst the parties involved. 6.1 Method A The test specimens shall be conditioned for 28 days at (23 2) C and (50 10) %

40、 relative humidity. 6.2 Method B The test specimens shall be conditioned according to method A and shall then be subjected three times to the following storage cycle: a) three days in the oven at (70 2) C; b) one day in distilled water at (23 2) C; c) two days in the oven at (70 2) C; d) one day in

41、distilled water at (23 2) C. Alternatively, this cycle may be carried out in the order c), d), a), and b). After conditioning according to method B, the test specimens shall be stored for 24 h at (23 2) C and (50 10) % relative humidity before testing. NOTE Method B is a normal conditioning procedur

42、e using the influence of heat and water. It is not suitable for giving information on the durability of the sealant.4 ISO 2015 All rights reserved ISO 11618:2015(E) 7 Definition of failure 7.1 General After preparation, the sealant test specimens shall be examined for defects. Any test specimens dee

43、med unsuitable for testing shall be rejected. After testing, the sealant test specimens shall be examined for evidence of loss of adhesion or cohesion. Wherever it is observed, the depth of adhesion loss and/or cohesion loss shall be measured using a suitable measuring device capable of reading to 0

44、.5mm. The highest observed value of the depth of either shall be recorded and used to determine a pass or failure. Due to the excessive stress experienced by the sealant near the ends of the test specimens during both the preparation and testing, loss of adhesion or cohesion observed within the excl

45、uded volume at either or both ends of the sealant shall not be reported as a failure (see ISO 11600, Figure 2). Each test shall be carried out in triplicate. In any test method, if two or more of the test specimens fail, then the sealant shall be reported as failing the test. If only one of the test

46、 specimens fails, then the complete test shall be repeated. If one of the three repeat test specimens fails, then the sealant has failed the test. 7.2 Additional note on failure Reference test methods are as given in ISO 8340, ISO 9047, and ISO 10590. If loss of adhesion or cohesion in the depth of

47、the sealant exceeds 2 mm anywhere on the sealant surface, then the sealant test specimen has failed (see ISO 11600, Figure 2). 7.3 Durability specimens Specimens shall be considered failed in the durability test when visible light is able to be observed through the sealant specimen assembly when the

48、 specimen is in its extended state. 8 Designation In the case of conformity with this International Standard, the sealants shall be designated by the symbols for the type, class, and the subclass in accordance with the following format: ISO 11618 - TYPE - CLASS SUBCLASS The packages shall be marked

49、with the appropriate designation of the sealant tested for which the holder of the test report takes responsibility. The substrates used in the tests and the primers used shall be shown on the package using the following abbreviations: mortar M1 or M2 (A) and primed (p) or unprimed (up). A full description of the test substrates may optionally be given on the package, but shall be given in the technical data sheet. EXAMPLE 1
