Описание (английский):

ISO 814:2017 specifies a method for determining the adhesion strength of rubber-to-metal bonds where the rubber part is assembled between two parallel metal plates, using the adhesive system under investigation. The method is applicable primarily to test pieces, prepared in the laboratory under standard conditions, such as can be used to provide data for the development of rubber compounds and control of methods of manufacture.

Overview

ISO 814:2017 - Rubber, vulcanized or thermoplastic - Determination of adhesion to metal - Two-plate method defines a standardized laboratory procedure to measure the adhesion strength of rubber-to-metal bonds when a rubber disc is sandwiched between two parallel metal plates. The method is intended for producing reliable adhesion data for rubber compound development and for manufacturing quality control of bonded rubber-to-metal assemblies.

Key topics and requirements

Test principle: Measure the maximum force required to rupture a rubber-to-metal bonded unit by pulling the metal plates apart at 90° to the bond.

Standard test piece:

Rubber cylinder thickness: 3 mm ± 0.1 mm; diameter between 35 mm and 40 mm (measured to 0.1 mm).
Metal plates: diameter ≈ 0.1 mm less than the rubber; plate thickness ≥ 9 mm; typically rolled carbon steel unless otherwise specified.

Apparatus and settings:

Tensile-testing machine meeting ISO 5893 requirements; force accuracy class 2.
Rate of traverse (separation): 25 mm/min ± 5 mm/min.
Inertialess (electronic/optical) dynamometers preferred to avoid inertial/friction errors.
Fixtures that allow accurate centring of the test piece.

Preparation and conditioning:

Test pieces moulded and cured under the adhesive system being evaluated; surfaces must be kept free of contamination.
Condition in accordance with ISO 23529 for at least 16 h at a standard laboratory temperature (23 °C ± 2 °C or 27 °C ± 2 °C) immediately before testing.
Minimum of three test pieces per test series.

Results and reporting:

Adhesion value = maximum force / cross-sectional area; reported in pascals (Pa).
Failure modes are recorded with standard symbols: R, RC, CP, PS, CS, D, S (definitions provided in ISO 814).
Test report must reference ISO 814 and include cure and conditioning details, specimen dimensions, materials, test temperature, individual results and failure-type percentages.

Calibration: Test apparatus must be calibrated per Annex A and guided by ISO 18899.

Applications and who uses it

ISO 814:2017 is used by:

R&D laboratories developing rubber compounds and adhesive systems.

Quality control and production engineers in manufacturers of rubber-to-metal bonded parts (e.g., mounts, seals, vibration isolators).

Accredited testing laboratories performing adhesion testing and material comparison. The method provides repeatable adhesion metrics useful for formulation optimization, process control, supplier verification and failure analysis.
