Additionally, outer or single sealants shall be capable of building up durable adhesive and cohesive strength to retain integrity of the edge seal system exposed to environmental and mechanical loads during the economically reasonable working life of IGU. Inner sealants may also be used as an assembly aid to bond the glass to the spacer bar during the manufacturing process. NOTE Other components of IGU edge seal can influence the durability of the edge seal. Supplier of sealant shall demonstrate the conformity with the declared characteristics by having the test report(s) issued in accordance with 5.6. SIST EN 1279-4:2018

EN 1279-4:2018 (E) 10 The required test reports shall contain the test results of relevant strength and substitution characteristics as specified in 5.3 and 5.5 respectively together with physicochemical characterization test results as specified in 5.2. The supplier of sealant shall demonstrate the compliance with additional requirements as specified in 5.4 by having test reports in accordance with EN 1279-2:2018 and, where relevant, with EN 1279-3:2018. Tests previously performed in accordance with the previous versions of EN 1279-2 and EN 1279-3 shall be also accepted. 5.2 Physicochemical characterization Physicochemical characterization of inner and outer sealants shall be carried out as given in Table 2. Chemically reactive systems shall be cured for 28 days at standard laboratory conditions, where applicable for test requirements. Table 2 — Physicochemical characterization of sealants Physicochemical characterization test Test method a Determination of change in volume EN ISO 10563 Infrared spectrum in the range from 400 cm «1 to 4000 cm «1, in ATR mode, on germanium, zinc sulphide or diamond, on the freshly cut surface of the sealant sample Thermogravimetric analysis EN ISO 11358-1:2014, 8.2, "Temperature scanning mode" Density / specific gravityb EN ISO 1183-1, procedure A a General requirements for all sealants are given in the table. See specific conditions for inner and outer sealants below in the text. b For cured sealant. For the thermogravimetric analysis apply following specific conditions. For inner sealant: — purging gas: nitrogen and synthetic air respectively, with flow rate approximately 100 ml/minute; NOTE 1 Flow rate deviations are depending on the type of the testing equipment. — sample size: approximately 10 mg; — heating rate: 20 K/minute; — heating mode: heating up from 40 °C to 800 °C in nitrogen flow, then 10 min isotherm in synthetic air flow, then heating up to minimum 850 °C, then 10 min isotherm at 850 °C in synthetic air. NOTE 2 During the initial heating (up to 800 °C, in nitrogen flow) the anaerobic decomposition and the desorption from carbon black filler of the materials occur. The remaining amount of carbon based material is determined by thermal oxidation in following heating steps in the flow of synthetic air. SIST EN 1279-4:2018

EN 1279-4:2018 (E) 11 For outer sealant: — conditioning before testing: at least 1 day at standard laboratory conditions; — purging gas: nitrogen and synthetic air respectively, with flow rate approximately 100 ml/min, depending on equipment; — sample size: approximately 50 mg; — heating rate: 20 K/minute; — heating mode: heating up from 40 °C to minimum 850 °C in nitrogen flow, then 10 min isotherm at 850 °C in synthetic air flow. The rate of heating shall not change during significant weight loss. In cases where the given method departs from this requirement, the method shall be adapted to prevent this. 5.3 Outer sealant strength When tested in accordance with Annex A, outer sealant shall show sufficient cohesive and adhesive strength before and after the aging. For each curve either the point of maximum tension or the point of failure or the end of each curve shall lie outside the triangle area defined by points A0B as shown in Figure c, shall be determined and declared (see also Figure A.5). If substitution of sealant is required, rules given in EN 1279-1:2018, Annex D shall be followed.

Figure 1 — Strength requirement for outer sealant If IGU manufacturer performs the sealing operation on a coated glass without deletion of the coating, a test report in accordance with Annex B shall be obtained. SIST EN 1279-4:2018

EN 1279-4:2018 (E) 12 NOTE 1 While it is assumed in this standard that sealant will always be in contact with float glass, it is the responsibility of the IGU manufacturer to ensure that the decision to skip edge deletion operation does not affect unacceptably the adhesion of sealant to glass and the durability of IGU.
