Overview

ISO 5892:2013 - Rubber building gaskets: Materials for preformed solid vulcanized structural gaskets - Specification defines material requirements for preformed solid vulcanized rubber structural gaskets used in sealing and supporting applications in buildings. The standard covers material types, working temperature ranges, mechanical and ageing performance, ozone resistance, and optional specific tests such as holding force and watertightness. It is intended for manufacturers, specifiers, test laboratories, façade engineers and procurement teams working with rubber building gaskets.

Key topics and technical requirements

• Material types
  • Type E: nominal hardness 75 ± 5 Shore A - intended for gaskets and lock strips.
  • Type F: nominal hardness 85 ± 5 Shore A - intended for lock strips only.
• Working temperature ranges (categories P1–P4)
  • P1: −20 °C to +55 °C
  • P2: −20 °C to +85 °C
  • P3: −40 °C to +70 °C
  • P4: −40 °C to +100 °C
• Mechanical and physical properties (see ISO 5892:2013 Table 1)
  • Tensile strength: minimum 12 MPa (both types)
  • Elongation at break: Type E ≥ 175%; Type F ≥ 125%
  • Compression set: max 35% after 24 h at 100 °C
• Ozone resistance
  • Standard ozone test: no cracking after 96 h at 40 °C under 20% elongation at 500 ppb (ISO 1431-1).
  • Optional high-density ozone resistance: no cracking after 96 h at 40 °C at 2 000 µg/m3.
• Accelerated ageing
  • Per ISO 188: test for 14 days at temperatures matched to working temperature category (examples in the standard: 70, 85, 100 or 125 °C).
  • Allowed changes from unaged values: Shore A change 0 to +10; tensile strength decrease ≤ 15%; elongation decrease ≤ 40%.
• Low-temperature performance
  • Brittleness: no failure at lowest temperature of intended use (ISO 812, procedure C).
  • Low-temperature compression set (after 24 h at −25 °C): median recovery ≤ 80% (Type E) and ≤ 90% (Type F) after 30 min.
• Optional specific tests
  • Holding force (Annex A): method for measuring force retaining glass/pressure plates (reported in N/m).
  • Watertightness, flammability, contact/migration staining: subject to agreement or national regulations.

Applications and users

• Applications: curtain walls, windows, doors, glazing gaskets, façade sealing and structural support where gaskets provide both support and airtight/watertight sealing.
• Who uses it: rubber extrusion and gasket manufacturers, façade and window system designers, building envelope engineers, specification writers, test labs and quality control teams, and purchasing/procurement departments requiring material performance acceptance criteria.

Related standards

Normative references (commonly used alongside ISO 5892:2013):

• ISO 37 (tensile testing), ISO 188 (accelerated ageing), ISO 7619-1 (durometer hardness), ISO 815-1/2 (compression set), ISO 1431-1 (ozone resistance), ISO 3302-1 (dimensional tolerances), ISO 3865 (staining), ISO 812 (low-temperature brittleness), ISO 15821 (watertightness testing).

Using ISO 5892:2013 in specifications ensures consistent material requirements and test methods for durable, ozone-resistant rubber building gaskets suitable for structural sealing and support in building envelopes.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
