Solar energy - Methods of testing preformed rubber seals and sealing compounds used in collectors
1.1 This International Standard gives requirements for the classification and testing of rubbers used to seal solar energy collectors in order to aid selection for specific applications.*NOTE Particular rubber applications, when specified, may necessitate other requirements that take precedence over these requirements.*1.2 The design requirements in this International Standard pertain only to permissible deflection of the rubber during thermal expansion or retraction of the seal in use and to the tolerances on dimensions of moulded and extruded seals.*1.3 This International Standard does not include requirements pertaining to geometrical design, fabrication or installation of the seals.*1.4 This International Standard is applicable in conjunction with long-term ageing and weathering tests. However, if long-term tests are performed, it is recommended that ISO 4892-2 be complied with for ageing tests and ISO 877 for accelerated weathering tests and material exposure tests, respectively.*NOTE The environmental conditions, test specimen configuration and any test deviations should be agreed upon between the parties involved. Also, if long-term tests are performed, the specific tests described in this International Standard should be*performed before and after long-term testing is carried out.
