Описание (английский):

This standard specifies the requirements and test methods for solid flat extruded sheets of impact-modified polystyrene (PS-I1) without fillers and reinforcing materials. This standard applies only to thickness 0,25 mm to 20,0 mm in accordance with clause 3. This standard also applies to PS-I sheet in roll form.

Overview

ISO 14615:1997 - Adhesives - Durability of structural adhesive joints - Exposure to humidity and temperature under load - defines a laboratory test method to evaluate the long-term performance of structural and semi-structural adhesive bonds when exposed simultaneously to elevated temperature, high humidity and static load. The method is particularly suitable for bonded joints in metal, composite and plastic adherends and is intended to simulate hot/humid service conditions to determine time to failure of adhesive joints.

Key topics and requirements

Test environment

Relative humidity maintained at 95%–100%.
Temperature cycled between 42°C and 48°C, with a full cycle of 60 min ±5 min (42 → 48 → 42 °C).
Insulated humidity cabinet with heated water reservoir and spray bars; heater/cooling capacity must meet defined ramp rates.

Apparatus

Humidity cabinet, heater and cooling unit, water circulation (with optional UV unit to control biological growth), and specimen-loading tubes with calibrated spring assemblies.
Spring assemblies typically apply ≈1 MPa to 7 MPa; secondary spring set to apply 1 MPa when fully compressed.

Specimens and joints

Common configurations: lap-shear (preferred) and T-joint specimens.
Typical lap-shear dimensions: 20 mm width with 10 mm overlap (or other dimensions with adaptation).
Adherend thickness normally 0.6 mm to 3 mm.
Bondline thickness controlled by spacers (glass spheres/wires); surface preparation per ISO 4588 or ISO 13895.

Procedure

Calibrate springs; assemble 3–6 specimens per loading tube; load using calibrated spring spacing; monitor tubes daily and replace failed specimens with solid strips until at least three joints have failed.
Record time to failure for each specimen and observe failure patterns per ISO 10365.

Results & reporting

Report individual and/or mean times to failure, applied load, specimen details, bond thickness, temperature cycle, failure modes, dates and all identifying information.

Applications and users

Use ISO 14615 to assess durability of structural adhesive joints for industries exposed to hot/humid environments:

Automotive, aerospace, marine, rail, electronics, construction and bonded-assembly manufacturing.

Typical users: adhesive manufacturers, test laboratories, OEM materials engineers, quality assurance teams, and R&D groups validating adhesive selection and joint design.
