Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references concerning such national
standards may be obtained on application to the Central Secretariat or to any CEN member.
This European Standard exists in three official versions (English, French, German). A version in any other language made by translation
under the responsibility of a CEN member into its own language and notified to the Central Secretariat has the same status as the official
versions.
CEN members are the national standards bodies of Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France,

1 Scope
This European Standard specifies the test methods for preformed joint seals made of vulcanised rubber for
use in concrete pavements.
2 Normative references
The following referenced documents are indispensable for the application of this European Standard. For
dated references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.
EN 26927:1990, Building construction — Jointing products — Sealants — Vocabulary (ISO 6927:1981)
ISO 37, Rubber, vulcanised or thermoplastic — Determination of tensile stress-strain properties
ISO 188, Rubber, vulcanized or thermoplastic -- Accelerated ageing and heat resistance tests
ISO 815, Rubber, vulcanised or thermoplastic — Determination of compression set at ambient, elevated or
low temperatures
ISO 1431-1, Rubber, vulcanised or thermoplastic — Resistance to ozone cracking — Part 1:Static and
dynamic strain testing
ISO 3384, Rubber, vulcanised or thermoplastic — Determination of stress relaxation in compression at
ambient and at elevated temperatures
ISO 2285, Rubber, vulcanized or thermoplastic -- Determination of tension set under constant elongation,
and of tension set, elongation and creep under constant tensile load
ISO 5893, Rubber and plastics test equipment — Tensile, flexural and compression types (constant rate of
traverse) — Specification
3 Terms and definitions
For the purposes of this European Standard, the terms and definitions given in EN 26927:1990 apply.
4 Test methods
4.1 Tensile strength and elongation at break
The tensile strength and elongation at break shall be determined by the method specified in ISO 37. Dumb-
bell shaped test pieces of types 1, 2, 3 or 4 shall be used. The test report shall report the type of test pieces
used.
NOTE Type 2 should be the preferred type.
4.2 Compression set in air
4.2.1 General
The measurements shall be carried out – if possible – in the direction of compression of the seal in service.
