9、 Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the

10、right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedu

It is recommended that th

30、e manufacturer be certified to a recognized quality management system. The certification authority may be the prime contractor.The purpose of acceptance inspection and tests of a solid rivet is to check, as simply as possible, using a method which is inexpensive but the most representative of the ac

31、tual conditions of use, with the uncertainty inherent in statistical sampling, that the solid rivets satisfy the requirements of this International Standard.Acceptance inspections and tests shall be carried out by the manufacturer, or under his responsibility.4.2 Acceptance inspection and test condi

32、tionsAcceptance inspections and tests (requirements, methods, and numbers of solid rivets) are specified in Table 1. They shall be carried out on each batch. Solid rivets shall be selected from the batch to be tested by simple random sampling.Each solid rivet may be submitted to several inspections

33、or tests, provided that none of characteristics to be verified has been previously altered during any of these inspections or tests.The solid rivets to be subjected to destructive inspections or tests may be those on which non-destructive inspections or tests have been carried out.A batch declared u

34、nacceptable after the acceptance inspection shall be resubmitted for acceptance only after all the defective units have been removed and/or defects have been corrected.In this case, the attribute(s) which caused the rejection shall be verified using a sample of twice the normal size with the same ac

35、ceptable limit.If the reason for rejection results from the method, the test apparatus or from faulty heat treatment which can be rectified in a satisfactory manner, the tests may be repeated after elimination of the cause, provided that any surface treatment be removed prior to heat treatment, with

36、out being detrimental to rivet final use. A note to this effect shall be added to the corresponding inspection documents.Unless otherwise specified, the test temperature shall be the ambient temperature.4.3 Use of statistical process control (SPC)When a characteristic is obtained by a controlled sta

37、tistical process, the manufacturer has the possibility, in order to declare conformity of the characteristic, of refraining from making the final systematic sampling provided for in this International Standard, if he is capable of formally justifying this choice by using ISO/TR 13425 and the standar

38、ds quoted in it as a basis.This justification will include the following phases: analysis of the products key characteristics; analysis of the risks for each implemented process; determination of the parameters and/or characteristics to be respected under SPC; determination of the capabilities of ea

39、ch process; drawing up an inspection plan and integration in the manufacturing process; drawing up of routes and control charts (ISO 7870-1, ISO 7870-2, and ISO 7870-3); ISO 2016 All rights reserved 3BS ISO 12289:2016ISO 12289:2016(E) use of control charts for data consolidation; determination of th

40、e audits to be run and the control to be carried out to ensure reliability of the device.To be usable in production, this process shall be or should be validated beforehand by the qualifying body, either during the qualification phase or a posteriori according to the case, by analysing the justifica
