Aerospace series - Qualification and approval of personnel for nondestructive testing

1.1 Purpose This document establishes the minimum requirements for the qualification and certification of personnel performing non-destructive testing (NDT), nondestructive inspection (NDI), or nondestructive evaluation (NDE) in the aerospace manufacturing, service, maintenance and overhaul industries. For the purposes of this document, the term NDT will be used and will be considered equivalent to NDI and NDE. In Europe, the term "approval" is used to denote a written statement by an employer that an individual has met specific requirements and has operating approval. The term "certification" as defined in 3.2 is used throughout this document as a substitute for the term "approval". Except when otherwise specified in the written practice, certification in accordance with this document includes operating approval. 1.2 Applicability This document applies to personnel who: - use NDT methods or equipment to test and/or accept materials, products, components, assemblies or sub-assemblies; - are directly responsible for the technical adequacy of the NDT methods and equipment used; - operate automatic interpretation or evaluation systems; - approve NDT procedures or work instructions; - audit NDT facilities; or - provide technical NDT support or training. This document does not apply to individuals who only have administrative or supervisory authority over NDT personnel or to research personnel developing NDT technology for subsequent implementation and approval by a certified Level 3. See Clause 8 regarding applicability to personnel performing specialized inspections using certain direct readout instruments. Definition Automated equipment refers to machinery and systems designed to perform tasks without human intervention. In a completely automated industrial process, these systems operate independently to execute various functions. 1.2.1 Implementation This document addresses the use of a National Aerospace NDT Board (NANDTB). NANDTBs are only used as specified per Annex C and it is not mandatory to have such a board for compliance with this document. Personnel certified to previous revisions of NAS410 or EN 4179 need not recertify to the requirements of this document until their current certification expires. 1.3 Methods 1.3.1 NDT methods This document contains detailed requirements for the following NDT methods: Eddy Current Testing (ET) Liquid Penetrant Testing (PT) Magnetic Particle Testing (MT) Radiographic Testing (RT) Shearography Testing (ST) Thermographic Testing (IRT) Ultrasonic Testing (UT) 1.3.2 Other methods When invoked by engineering, quality, cognizant engineering organization or prime contractor requirements, this document applies to other current and emerging NDT methods used to determine the acceptability or suitability for intended service of a material, part, component, sub-assembly or assembly. Such methods include, but are not limited to, acoustic emission, neutron radiography, leak testing, and holography.

Nafta ir panašūs produktai. Matavimo metodų ir rezultatų glaudumas. 2 dalis. Bandymo metodų glaudumo duomenų aiškinimas ir taikymas (ISO/DIS 4259-2:2025)

ISO 4259-2:2017 specifies the methodology for the application of precision estimates of a test method derived from ISO 4259‑1. In particular, it defines the procedures for setting the property specification limits based upon test method precision where the property is determined using a specific test method, and in determining the specification conformance status when there are conflicting results between supplier and receiver. Other applications of this test method precision are briefly described in principle without the associated procedures. The procedures in ISO 4259-2:2017 have been designed specifically for petroleum and petroleum-related products, which are normally homogeneous. However, the procedures described in ISO 4259-2:2017 can also be applied to other types of homogeneous products. Careful investigations are necessary before applying ISO 4259-2:2017 to products for which the assumption of homogeneity can be questioned.

Nafta ir panašūs produktai. Matavimo metodų ir rezultatų glaudumas. 1 dalis. Bandymo metodų glaudumo duomenų nustatymas (ISO/DIS 4259‑1:2025)

ISO 4259-1:2017 specifies the methodology for the design of an Interlaboratory Study (ILS) and calculation of precision estimates of a test method specified by the study. In particular, it defines the relevant statistical terms (Clause 3), the procedures to be adopted in the planning of ILS to determine the precision of a test method (Clause 4), and the method of calculating the precision from the results of such a study (Clauses 5 and 6). The procedures in ISO 4259-1:2017 have been designed specifically for petroleum and petroleum related products, which are normally considered as homogeneous. However, the procedures described in ISO 4259-1:2017 can also be applied to other types of homogeneous products. Careful investigations are necessary before applying ISO 4259-1:2017 to products for which the assumption of homogeneity can be questioned.

Kranai. Prieigos

This document specifies design requirements for non-powered access installed on cranes. NOTE 1 For other type of access, a requirement for information to be supplied is specified. Slidable, retractable means of access are excluded from the scope, except movable hoop guards. This document covers means of access to control stations and all access required for maintenance, certain erection and dismantling operations. For those cranes which are intended to be erected and dismantled frequently to change their places of work, specific requirements for the access needed during these operations are not covered by this document and can be given in the appropriate European Standards for specific crane types. Lighting of means of access is not covered by this document and can be given in the appropriate European Standards for specific crane types. NOTE 2 Specific requirements for access on particular types of cranes are given in the appropriate European Standard for the particular crane type. The requirements given in this document do not take into account the safety distances related to: - guarding against hazard from moving parts; - relative movement between crane and adjacent structure or the ground/floor; - hazardous surface temperature; - electrical equipment. The significant hazards covered by this document are identified in Annex A. This document is not applicable to cranes manufactured before the date of its publication.
