1 asme Section - V Edition 2019 code Changes Diwakar Joshi1, Aditya Bhagwat2, Gajanan Joshi3 Insight Quality Services, Office No. 507/508, 5th Floor, Building , Siddharth Towers, Sr. No. 12/3B, Near Sangam Press, Kothrud, Pune - 411 029, Maharashtra, India E-mail ID: E-mail ID: Email ID: ABSTRACT asme (American Society for Mechanical Engineers) Codes are revised every 2 years (generally on 1st July), and the new Edition is mandatorily applicable after six months (on subsequent 1st January onward). After Edition 2017 (which is applicable up to 31st December 2019 ), the new Codes are released on 1st July, 2019 which are available all over now. asme code Section V, Nondestructive Examination, is a referenced code referred by many referencing Codes like asme Section VIII Div. 1 (Pressure Vessel), asme Section I (Power Boilers), asme Section III (Nuclear). The manufacturers having asme code certification, Owners, Users, Consultants, Inspectors and the Fabricators need to know what are the Changes in the new code and why are these Changes made, to align themselves and act as per new code .

2 This paper gives the Summary of major Changes in asme Section V - 2019 from the earlier code Edition 2017, and discusses how to implement these Changes . Keywords: asme , Manufacturer, Pressure Vessel, Nondestructive Examination, Changes NDE2019, 054, v1: asme Section - V Edition 2019 code Changes 1 More info about this article: Section V is a referenced code which deals with NDE requirements like Personnel Qualifications, Procedures, Equipment, Calibrations and Demonstration of the NDE procedures. It is to be referred to when a Referencing code (like asme Section VIII Div. 1, asme Section VIII Div. 2, asme Section VIII Div. 3, asme Section III, asme Section I, asme Section IV, asme , asme B , AWS and so on) directs you to refer to it. While directing you to Section V, the referencing code always adds or deletes the requirements of Section V before making the Procedures.

3 The acceptance Standards are always given by referencing Codes. Some examples of such additions/deletions are a) UW-51 states that the requirements of T-274 (Geometric Unsharpness) is used as guide only. b) In asme Section III NB the requirements of penatrameter is not as per asme Section V T -276. We have to refer Table NB 5111-1 which is stricter than asme Section V- T - 276. c) As per asme Section I PW-51, the requirements of T-274 are to be used as a guide but not for the rejection of radiographs unless the geometrical unsharpness exceeds in ( mm). Why are Changes made in Codes? It is to address new methods, new techniques, new equipment, like PAUT, DR, CR, FMC. To give more clarity on the practices followed and define the parameters and ranges of parameters within which the procedure can be used, the essential variables were added in asme Section V for all methods (except radiographic testing) in asme Section V Edition 2001 Addendum 2002.

4 To correct the practices in NDE (wrong interpretations and unintended mistakes to be eliminated). To give more clarity to the code requirements . To correct the grammatical and typographical errors. To clarify the conversion factors and units to be used. The present asme Section V Edition 2019 was released on 1st July 2019 and will be mandatorily applicable from 1st January 2020. All the Changes listed in summary of Changes can be divided into Major Changes (wherein change of procedure, format, equipment and training is essential.) Changes which are for information only Changes initiated due to typographical errors, errata etc. We are going to discuss only the major Changes in the code . Needless to say, one has to refer to the Original code to understand and implement the Changes effectively. Article 1 1. The main change in asme Section V Edition 2019 is the adopting of SNT-TC-1A Edition 2016 and ANSI/ASNT CP-189 Edition 2016.

5 For implementation of this, asme Section V added Mandatory appendix III and IV for SNT-TC-1A and CP 189 respectively. Major Changes in recommendations of SNT TC-1A Review of 1000 radiographs is not required for demonstrating experience in limited certification of Radiographic Examination Film Interpretation. The practical examination shall consist of a sufficient number of radiographs to demonstrate satisfactory performance to the certifying Level III or sufficient documented experience as deemed appropriate by the certifying Level III. Personnel being considered for initial certification shall complete sufficient organized training to become thoroughly familiar with principles and practices of the specified NDE method 2 NDE2019, 054, v1: asme Section - V Edition 2019 code Changes related to the level of certification desired and applicable to the processes used and products to be examined.

6 Hours shall not be credited for self-study scenarios. The Practical examination shall have a passing grade of at least 80 percent. Near-Vision acuity examination shall be administered annually. The examination shall ensure natural or corrected near-distance acuity in at least one eye such that the applicant is capable of reading a minimum of Jaeger Number 1 or equivalent type and size letter at the distance designated on the chart but not less than 12 in. ( cm) on a standard Jaeger test chart or an equivalent Ortho-Rater or similar test pattern. The candidate shall detect at least 80% of discontinuities and conditions specified by the NDE Level III. Maximum recertification intervals shall be 3 years for Level I and Level II personnel, and 5 years for Level III personnel. Certifications expire 3 or 5 years from the date of the first examination taken during initial or recertification activities for each method.

7 SNT TC-1A Clause No. shall not be allowed, which states that the employer may delete the specific examination if the candidate has a valid ASNT NDT Level III or ACCP Professional Level III certificate in the method and if documented evidence of experience exists, including the preparation of NDT procedures to codes, standards, or specifications and the evaluation of test results. Major Changes in requirements of CP - 189 Definition added - Personalized Instruction. Personal Instruction may consist of blended classroom, supervised laboratory, and/or hybrid online competency-based course delivery. Modular content is addressed through online presentations, in the classroom, and/or in small groups. Personalized instruction also enables students to achieve competency using strategies that align with their knowledge, skills and learning styles. As described in CP-189 paragraph , self-study as an acceptable form of training is deleted.

8 Removed the requirement for a Company Level III to be certified by ASNT for their Initial Certification. Removed waiver of employer based Specific Examination for ASNT certified Level II. Removed waiver of employer based Specific Examination for ACCP certified Level II. Mandated that the candidate receive at least 80% in the Practical Examination. Added the requirement for the Level III to sign the candidate s certification. Tied the expiration of a certification to when the examination was taken should it be taken over successive days Clause : 5 years from the day of the first examination for each method NDE Level I, NDE Level II and NDE Level III individuals; 2. T- 150 (d) is revised for clarity that where Procedure Qualification is required by the Referencing code , demonstration shall be performed prior to the acceptance of production examination. 3.

Mandatory Appendix III and IV added for Implementation of SNT-TC-1A and CP-189 Edition 2016. Article 2 1. T- 223 revised to reflect a minimum dimension of 7/16 in. (11 mm) for the required height of a lead symbol B for the determination of the presence of backscattered radiation. 2. revised for densitometer calibration - 90 days is replaced by 3 months for clarity. 3. revised to clarify that the essential wire shall be visible within the area of interest representing the thickness used for determining the essential wire (inclusive of allowable density and brightness variations). NDE2019, 054, v1: asme Section - V Edition 2019 code Changes 3 Article 4 1. Consolidated the variables for phased array examinations in a user-friendly format. Added several variables based on lessons learned, qualification experiences, and enhanced equipment capabilities.

10 Clarified the need for scan plans in Article 4. 2. Added T-420(e) to reference Article 4, Mandatory Appendix V. 3. Changed the reference in Figure , Note (2) from (incorrectly directing the user to the paragraph for setting up a DAC curve with notches) to (correctly directing the user to the paragraph for setting up a DAC curve using side-drilled holes). 4.
