Scope

1.1 This Part of GB/T 1043 specifies a method for determining the Charpy
impact strength of plastics under defined conditions. A number of different types
of specimen and test configurations are defined. Different test parameters are
specified according to the type of material, the type of test specimen and the
type of notch.
1.2 This Part is used to investigate the behavior of specified types of specimen
under the impact conditions defined and for estimating the brittleness or
toughness of specimens within the limitations inherent in the test conditions. It
may also be used for the determination of comparative data from similar types
of material.
1.3 This Part has a greater range of applicability than that given in GB/T 1843
and is more suitable for the testing of materials showing interlaminar shear
fracture or of materials exhibiting surface effects due to environmental factors.
1.4 This Part is suitable for use with the following range of materials:
- rigid thermoplastic moulding and extrusion materials, including filled and
reinforced compounds in addition to unfilled types; rigid thermoplastics
sheets;
- rigid thermosetting moulding materials, including filled and reinforced
compounds; rigid thermosetting sheets, including laminates;
- fibre-reinforced thermosetting and thermoplastic composites incorporating
unidirectional or non-unidirectional reinforcements such as mat, woven
fabrics, woven rovings, chopped strands, combination and hybrid
reinforcements, rovings and milled fibers, sheet made from pre-
impregnated materials (prepregs), including filled and reinforced
compounds;
- thermotropic liquid-crystal polymers.
1.5 This Part is not normally suitable for use with rigid cellular materials and
sandwich structures containing cellular material. Also, notched specimens are
not normally used for long-fiber-reinforced composites or thermotropic liquid-
crystal polymers.
1.6 This Part is suited to the use of specimens which may be either moulded to
the chosen dimensions, machined from the central portion of a standard
multipurpose test specimen (see GB/T 11997) or machined from finished or
semi-finished products such as mouldings, laminates and extruded or cast
sheet.
1.7 This Part specifies preferred dimensions for the test specimen. Tests which
are carried out on specimens of different dimensions or with different notches,
or specimens which are prepared under different conditions, may produce
results which are not comparable. Other factors, such as the energy capacity
of the apparatus, its impact velocity and the conditioning of the specimens can
also influence the results. Consequently, when comparative data are required,
these factors must be carefully controlled and recorded.
1.8 This Part should not be used as a source of data for design calculations.
Information on the typical behavior of a material can be obtained, however, by
testing at different temperatures, by varying the notch radius and/or the
thickness and by testing specimens prepared under different conditions.

Summary	This standard specifies the method for the determination of plastic under specified conditions Charpy impact strength. Provides sample and test several different types. According to the material type, notched specimen types and provides different types of test parameters. This section is used to study and evaluate the behavior of a sample of the type specified conditions of impact of the sample under test conditions in the brittle and ductile. Similar materials can also be used to determine comparable data.
