30、as defined in 1.3.1. 4.3 LEVEL 1-LIMITED When authorized by the cognizant engineering organization and the employers written practice, the performance of a specific NDT test on a specified part, feature, or assembly may be performed by personnel certified to Level 1-Limited. Each use of Level 1-Limi
31、ted is a separate certification and shall be approved by the cognizant engineering organization. An individual shall not possess more than three Level 1-Limited certifications at any given time. The following shall be documented and be made available for review by the employers customers and regulat
32、ory agencies: prEN 4179:2014 (E) 12 The case-by-case justification for using Level 1-Limited The cognizant engineering organization approval The training and experience hours and the number of examination questions The specific NDT test to be performed The specific hardware to be tested The authorit
33、y to accept or reject hardware, if applicable 4.4 RESPONSIBILITY The employer is responsible for the implementation of, and compliance with, this standard and for certifying qualified personnel. In addition, the prime contractor shall be responsible for compliance to this standard by their sub-contr
34、actors. Employers using outside agencies shall be responsible for assuring that the appropriate requirements of this standard are met. The employer is solely responsible for the certification of its employees and cannot certify for another employer. Individuals cannot qualify themselves. Self-employ
35、ed individuals may certify themselves provided they have a written practice and have been qualified to the requirements of this standard by another individual certified to Level 3 in accordance with this standard. 4.4.1 RESPONSIBLE LEVEL 3 The employer shall identify in writing a “Responsible Level
36、3” to act on its behalf in matters regarding the NDT qualification and certification process. The Responsible Level 3 shall be certified in accordance with this standard as a Level 3 in one or more NDT methods and shall have a thorough knowledge of the written instructions, codes, specifications and
37、 standards used by the employer. He/she shall also have a thorough knowledge of the materials, components, product technologies, NDT methods and NDT techniques used by the employer. Additional Examiners as defined in this standard may be identified and delegated in writing as necessary to provide co
38、verage for all methods used by the employer. The Responsible Level 3 may be an outside agency but in this case he/she can only qualify personnel, as only the employer can certify personnel. The Responsible level 3 shall be responsible for implementation of this standard and the overall administratio
39、n of the qualification and certification program. 4.4.2 NATIONAL AEROSPACE NDT BOARD (NANDTB) The organization has a constitution, a deciding entity, and governed according to administrative and working procedures. The voting members in the deciding entity are NDT Level 3 personnel and are from part
40、icipating prime contractors or type certificate holders as a minimum. Other members may be co-opted as voting or non-voting members as necessary to support the NANDTB. Regulatory agencies for civilian and/or defense have the right to be included as observer members. The Responsible Level 3 may use a
41、n NANDTB to: Develop training course outlines and training material Create examination questions and administer examinations Approve outside and/or internal organizations providing training and/or examination services Define requirements for qualification of NDT personnel in emerging NDT methods Ret
42、ain written and practical examinations Designate Examiners and/or instructors at outside or internal organizations providing training and examination services Where an NANDTB is used to provide such services, it shall develop processes and procedures that shall ensure full compliance with the requir
43、ements of this standard. The activities, processes, procedures, technique catalogs, etc. undertaken/developed by an NANDTB shall be made available for review by prime contractors and regulatory agencies. For countries where no NANDTB exists, the services of other NANDTBs may be used, but are not req
44、uired to do so, unless specified by local or regulatory requirements. 4.4.3 OUTSIDE AGENCY An employer may use a Level 3 certified in accordance with this standard from an outside agency to develop a certification program, act as the Responsible Level 3, examine NDT personnel or perform any other qu
45、alification or Level 3 function. An outside agency may qualify, but not certify personnel. The employer shall document the suitability of any outside agency selected to perform any function in meeting the requirements prEN 4179:2014 (E) 13 of this standard.

46、detail to justify the outside agencys ability to perform the required Level 3 function(s). 5. QUALIFICATION AND CERTIFICATION LEVELS 5.1 LEVELS OF QUALIFICATION AND CERTIFICATION The four basic levels of certification are Level 1-Limited, Level 1, Level 2 and Level 3. The employer may subdivide, add
47、 or limit levels as appropriate, but cannot eliminate or reduce the minimum requirements for each level. If the employer does not wish to use all of the levels, those levels to be used shall be documented in the employers written practice. Where other variations or subdivisions are implemented, the
48、requirements and responsibilities shall also be detailed in the employers written practice. NDT personnel shall not independently perform the functions listed in 5.1.2, 5.1.3, 5.1.4 and 5.1.5 if not certified to the appropriate level in the applicable technique/method. 5.1.1 TRAINEE An individual wh
49、o is documented as participating in a training program for an NDT method and is in the process of becoming qualified for certification to Level 1, Level 1-Limited or directly to Level 2 shall be considered a trainee. In the technique/method in which they are preparing for certification, trainees shall: Be documented as a trainee and be actively participating in a training program for a stated NDT method for a limited and specified period of time.
