5 Notes on testing

5.1 Material

The identity test is performed using infrared spectroscopy.

5.2 Tensile strength and elongation at tear

S3A specimens. The tensile specimens shall be taken from the hose material to be tested in the direction of extrusion; test rate 100 mm/min.

5.3 Shore A hardness in moist condition

Aging of five hose sections, 50 ±1 mm in length, in 250 ±10 ml FAM test fluid according to DIN 51 604-2; aging duration 48 - 2 h; aging temperature 23 ± 2 °C. The hardness measurement shall be performed after the specimens have been aged in air for 15 + 2 min at 23 ± 2 °C.

5.4 Shore A hardness in dry condition

Aging of five hose sections, 50 ±1 mm in length, in 250 ±10 ml FAM test fluid according to DIN 51 604-2; aging duration 48 - 2 h; aging temperature 23 ± 2 °C. The hardness measurement shall be performed after the specimens have been dried in mechanically circulated air at 70 ± 2 °C for 48 - 2 h and subsequent cooling to 23 ± 2 °C.

5.5 Tensile strength and elongation at tear in dry condition

Five S3A tensile specimens which have been previously measured in the cross section and taken from the hose material to be tested in the direction of extrusion are aged according to DIN 53 504 in 250 ±10 ml of FAM test fluid according to DIN 51 604-2; aging duration 48 - 2 h; aging temperature 23 ± 2 °C. The measurements shall be taken after the specimens have been aged in air for 15 + 2 min at 23 ± 2 °C in accordance with section 5.2.

5.6 Weight

Aging of five hose sections, measuring 50 ± 1 mm in length, which have been previously weighed accurate to 0.001 g, in 250 ±10 ml FAM test fluid according to DIN 51 604-2; aging duration 48 – 2 h; aging temperature 23 ±2 °C. The specimens shall be re-weighed after being dried in mechanically circulated air at 70 ± 2 °C and subsequent cooling to 23 ± 2 °C.

behavior

5.7 Low-temperature

Hose sections measuring approx. 100 mm in length shall be mounted on connecting t-pieces or adapters in accordance with the drawing, secured using the clamps provided and aged immediately after assembly for 22 + 2 h in air at -40 ±1 °C. The specimens are evaluated immediately after removing them from the cold chamber. A minimum of 3 specimens must be tested.
