The manufacturer of these parts shall

34、 have a quality system that complies with EASA / FAA or an equivalent regulation such as SAE AS 9100 / EN 9100.Quality documentation for parts produced in accordance with this International Standard, shall be maintained for a minimum period of 10 years.The approval of the manufacturer shall be grant

35、ed by the Certification Authorities, or their appointed representative, who may be the prime contractor.4.1.2 Qualification of boltsThe purpose of inspections2)is to verify that the design and manufacturing conditions of a bolt enable it to satisfy the requirements of this International Standard.The

36、 qualification shall be granted by the Certification Authorities in the purchasers country, or their appointed representative, who may be the prime contractor.4.1.3 Acceptance of boltsThe purpose of inspections is to verify, as simply as possible, using a method which is inexpensive, with the uncert

37、ainty inherent in statistical sampling, that the bolts satisfy the requirements of this International Standard.They shall be carried out by the manufacturer or under his responsibility.The manufacturer is responsible for the quality of the bolts manufactured.4.2 Qualification inspection conditionsUn

38、less otherwise specified, the inspection shall be carried out on the following: each type and diameter of bolt; 28 bolts selected from a single inspection lot by simple random sampling.2) In order to simplify the text, the term “inspections” used in this International Standard also refers to “inspec

39、tions and tests”. ISO 2016 All rights reserved 3BS ISO 9154:2016ISO 9154:2016(E)The test programme may possibly be reduced, or the qualification granted, without inspection: Any such decision shall be based on the results obtained on similar types and diameters of bolts, provided that the design and

40、 manufacturing conditions are identical.The inspections shall be repeated on any bolt if the manufacturing conditions have modified.Table 2 indicates the allocation of bolt sample for the inspections.4.3 Acceptance inspection conditionsInspections shall be carried out on each production batch or ins

41、pection lot. Bolts from the batch or lot to be inspected shall be selected by simple random sampling.Each bolt may be submitted to several inspections, provided that none of characteristics to be verified has been previously altered during any of these inspections.The bolts to be subjected to destru

42、ctive inspections may be those on which non-destructive inspections have been carried out.If a more stringent inspection is deemed necessary, all or part of the qualification inspections may be performed during the acceptance inspections. In this case, the number of bolts submitted is the same as th

43、at submitted for qualification inspection.Production batches or inspection lots declared unacceptable after the production acceptance inspections shall be submitted for re-inspection only after all the defective units have been removed and/or defects have been corrected. In this case, the attribute(

44、s) which caused the rejection shall be verified using a sample of twice the normal size with the same number of defective items acceptable.4.4 Use of “statistical process control (SPC)”When a characteristic is obtained by a controlled statistical process, the manufacturer has the possibility, in ord

45、er to declare conformity of the characteristic, of refraining from 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 standards quoted in it as a basis.This justification will include the follow

46、ing phases: analysis of the key characteristics of the product; 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 each process; drawing up an inspection plan and integration in th

47、e manufacturing process; drawing up of routes and control charts (ISO 7870-1, ISO 7870-2, ISO 7870-3); use of control charts for data consolidation; determination of the audits to be run and the control to be carried out to ensure reliability of the device.To be usable in production, this process sh

48、all or should be validated beforehand by the qualifying body, either during the qualification phase, or a posteriori according to the case, by analysing the justificatory file and the results of the qualification inspections such as provided for in Clause 5. Such SPC process not applicable to destru

49、ctive tests apart from the measurement of the hydrogen content.4 ISO 2016 All rights reservedBS ISO 9154:2016ISO 9154:2016(E)5 RequirementsThe requirements of this International Standard are given in Table 1 and, unless otherwise specified, they apply to bolts ready for use. The test temperature, unless otherwise specified, shall be the ambient temperature. These requirements complement the requirements of all other standards or specifications referenced in the definition document.Table 1 Requirements and test
