Notes on testing

5.2 Moisture

A minimum of three specimens measuring (20 x 20) mm shall be removed from different points on

the finished part; they shall be weighed with an accuracy of 0.01 g and dried in a vacuum until the weight value remains constant. Cooling of the specimens to (23 ± 2) °C, which is necessary for the

5.3 The measurements must be performed on at least three specimens (minimum thickness 4 mm)

measuring (20 x 20)

mm (two measurements per specimen). The grained surface of specimens, which have been taken from finished parts with one-sided graining, shall be removed using

5.5 Aging

Complete finished parts or finished part sections shall be aged for 1,000

h at (150 ± 1) °C in a drying cabinet. The viscosity number of the polymer is determined after cooling to (23 ± 2) °C.

A minimum of 3 whole finished parts are aged in coolant according to TL 774 without adding water. The type currently used for the factory filling is to be used.

Aging period: 48 h; aging temperature: (135 ± 1) °C.Aging is to be performed using a thermostat with circulated bath (e.g., Lauda Ultra Thermostat 6 Referenced standards *)
