D 5 Notes on testing
5.1 Material
The identity test is performed using infrared spectroscopy.
5.2 Yield stress
Tensile test according to DIN EN ISO 527-2, S2 specimens according to DIN 53504; test rate v = 50 mm/min ± 10%.
5.3 Modulus of elasticity
3-point bending test: measurement in standard climate or at -40 °C in constant-temperature chamber.
Specimens: 50 mm x 10 mm x product thickness (up to max. 4 mm); support paration: 40 mm
5.4 Notched impact strength
Impact resistance test (broadside impact) according to DIN EN ISO 179-1; deviating specimen length: (50 ±1) mm; width: (6 ± 0.2) mm; thickness according to finished part thickness (up to max.
4 mm); support paration: 40 mm; test apparatus: pendulum impact tester 4J.
The specimens are given a 0.8 mm wide U-shaped notch on the broad side. The notch depth shall be 1/3 the specimen thickness. The edges adjoining the ba of the notch must have a curvature radius of < 0.1 mm.
大厦打一字Specimens taken from molded parts with one-sided graining or paint shall be notched on the grained or painted side and placed on the support so that the center of the notch is exactly in the center of the striking plane and the notch is turned away from the direction of impact.
5.5 Impact resistance
Testing according to DIN EN ISO 179-1; deviating specimen length: (50 ± 1) mm; width: (6 ± 0.2) mm; thickness according to finished part thickness (up to max. 4 mm); support paration: 40 mm, test equipment: pendulum impact tester 4J.
Specimens taken from molded parts with one-sided graining or paint shall be placed on the support of the pendulum impact tester so that the grained or painted side faces the direction of impact.
5.6 Aging at elevated temperature
Continuous aging in mechanically circulated air at (+150 -1) °C. The test is preferably performed on
complete finished parts. It is permissible to perform it on ctions of finished parts. Brittling is reached when the specimen exhibits signs of disintegration typical for decompod PP at any point (material starts to crumble).
5.7 Low-temperature behavior
Low-temperature aging of at least one finished part.
Aging temperature: (-40 ± 2) °C, aging duration: (22 +2) h.
