National foreword This document (EN ISO 13802:2015) has been prepared by Technical Committee ISO/TC 61 “Plastics” in collaboration with Technical Committee CEN/TC 249 “Plastics” (Secretariat: NBN, Belgium). The responsible German body involved in
6、its preparation was DIN-Normenausschuss Kunststoffe (DIN Standards Committee Plastics), Working Committee NA 054-01-02 AA Mechanische Eigenschaften und Probekrperherstellung. The International Standards referred to in Clause 2 have been published as the corresponding DIN EN ISO Standards with the sa
7、me number. Amendments This standard differs from DIN EN ISO 13802:2006-06 as follows: a) Clause 1 “Scope” has been rendered more precise; b) Clause 3 “Terms and definitions” has been extended; c) Clause 5 “Description of a pendulum impact-testing machine” has been added; d) Clause 6 on the verificat
8、ion and inspection of a pendulum impact testing machine has been revised; e) Clause 7 “Frequency of verification” has been revised; f) Annex F (informative) on gauge plates for verifying Charpy impact pendulums has been added; g) the standard has been editorially revised. Compared with DIN EN ISO 13
9、802:2015-11, the following corrections have been made: a) in Table 4, the pendulum length, LP, in m, has been changed from “0,225 to 0,390” to “0,221 to 0,417” (based on ISO 13802:2015, corrected version 2016-04-01); b) in Subclause 6.5.1.2, a correction has been made to the German version only and
10、therefore does not affect the English text (“ 5 mm” now correctly reads “ 0,5 mm”); c) the standard has been editorially revised.

39、 ISO 13802:2015 (E)5 1 ScopeThis International Standard specifies frequency and methods for the verification of pendulum impact-testing machines used for the Charpy impact test, Izod impact test, and tensile impact test described in ISO 179-1, ISO 180, and ISO 8256, respectively. Verification of ins
40、trumented impact machines is covered insofar as the geometrical and physical properties of instrumented machines are identical to non instrumented machines. The force/work verification of instrumented machines is not covered in this International Standard.This International Standard is applicable to
41、 pendulum-type impact-testing machines, of different capacities and/or designs, with the geometrical and physical properties defined in Clause 5.Methods are described for verification of the geometrical and physical properties of the different parts of the test machine. The verification of some geom
42、etrical properties is difficult to perform on the assembled instrument. It is, therefore, assumed that the manufacturer is responsible for the verification of such properties and for providing reference planes on the instrument that enable proper verification in accordance with this International St
43、andard.These methods are for use when the machine is being installed, has been repaired, has been moved, or is undergoing periodic checking.A pendulum impact-testing machine verified in accordance with this International Standard, and assessed as satisfactory, is considered suitable for impact testi
44、ng with unnotched and notched test specimens of different types.Annex A details design requirements for Charpy testing machines.Annex B details design requirements for Izod testing machines.Annex C details design requirements for tensile impact machines.Annex D explains how to calculate the ratio of
45、 frame mass to pendulum mass required to avoid errors in the impact energy.Annex E explains deceleration of pendulum during impact.Annex F details design requirements for one type of gauge used to verify striker and anvil/support alignment for Charpy testing machine.2 Normative referencesThe followi
46、ng documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies.
