Fire reaction and Euroclass classification per EN 13501-1 — conducting ignitability, flame spread, and heat release tests to assign the required fire safety class for European construction products.
Creep and long-term deformation per ASTM D2990 — applying sustained compressive stress at elevated temperature to predict dimensional changes over the design life of insulated panels.

Polyurethane Elastomer and Rubber Testing

Hardness by Shore A and Shore D per ISO 48-4, ASTM D2240 — measuring indentation hardness to classify elastomer grades for sealing, damping, or load-bearing functions.
Tensile strength and tear resistance per ISO 37, ISO 34-1, ASTM D412, and ASTM D624 — pulling and tearing specimens to evaluate the material's ability to withstand mechanical stress, cuts, and propagation of nicks.
Abrasion resistance per ISO 4649 and ASTM D5963 — subjecting elastomer samples to standardized abrasive wear to rank durability for rollers, wheels, and conveyor components.
Compression set and stress relaxation per ISO 815-1 and ISO 3384 — measuring residual deformation and force decay after sustained compression to predict seal performance over time.
Dynamic mechanical analysis per ISO 6721 — characterizing storage modulus, loss modulus, and damping behavior across temperature and frequency to support vibration isolation design.
Chemical resistance to oils, fuels, and cleaning agents per ISO 1817 and ASTM D471 — immersing elastomers in service fluids to measure changes in mass, hardness, and tensile properties.
Low-temperature flexibility and brittleness per ASTM D2137 — testing behavior at sub-zero temperatures to ensure reliable sealing and flexibility in cold climates.

Polyurethane Coating and Adhesive Testing

Adhesion by pull-off, cross-cut, and peel tests per ISO 4624, ISO 2409, ASTM D4541, and ASTM D903 — quantifying bond strength to metal, concrete, plastic, and wood substrates for coating and adhesive qualification.
Hardness and scratch resistance per ISO 15184, ASTM D3363 — applying pencil and stylus scratch methods to evaluate surface durability and resistance to marking.
Flexibility and impact resistance per ISO 1519, ASTM D522, and ASTM D2794 — bending and impacting coated panels to ensure the film does not crack or delaminate under deformation.
Water absorption and vapor transmission per ASTM D570 and ASTM E96 — measuring moisture uptake and permeability to verify barrier performance in protective coatings.
