BOS ISO 9553_1997

Description

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.
