BS EN ISO 6603-1:2000

1   Scope 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](/search?q=ISO%C2%A07765) 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](/search?q=ISO%C2%A06603-1) and [ISO 6603-2](/search?q=ISO%C2%A06603-2). 

These methods are suitable for use with the following types of material:

       —  rigid thermoplastic moulding and extrusion materials, including filled, unfilled and reinforced compounds and sheets;
