Plastics — Determination of puncture impact behaviour of rigid plastics — Part 1: Non-instrumented impact testing

This International Standard specifies methods for the determination of puncture-impact properties of rigid plastics in

the form of flat test specimens, such as discs or square pieces, under defined conditions. Specimens may be

moulded directly, cut from sheets or taken from finished products. Different types of test specimens and test

conditions are defined.

These falling-dart methods are used to investigate the behaviour of plastic sheeting or mouldings under the impact

of a striker applied perpendicular to the plane of the specimen.

This part of ISO 6603 can be used if it is sufficient to characterize the impact behaviour of plastics by a threshold

value of impact-failure energy based on many test specimens. ISO 6603-2 is used if a force-deflection or force-time

diagram, recorded at nominally constant striker velocity, is necessary for detailed characterization of the impact

behaviour.

These test methods are applicable to specimens with a thickness between 1 mm and 4 mm.

NOTE For thicknesses less than 1 mm, ISO 7765 should preferably be used. Thicknesses greater than 4 mm may be

tested if the equipment is suitable, but the test falls outside the scope of ISO 6603-1 an
