Check what the differences are between ASNT, PCN, and ISO standards and certifications

 

 

Hello, welcome to the Industrial Inspector website. Today we'll be discussing the standards used in non-destructive testing (NDT). In this article, we'll explore the differences between three of the most common standards and certifications, namely ASNT, PCN, and ISO.

 

It's important to note that there are more standards such as DIN (Deutsches Institut für Normung), a German standard, and ABENDI (Associação Brasileira de Ensaios Não Destrutivos e Inspeção), a Brazilian one. However, we want to highlight that there are several standards governing NDT, but when a professional moves from one location to another, ISO standards are used for analysis and to reach a conclusion. Today, companies are increasingly aware of the importance of quality and safety in their operations. To ensure this, they often turn to internationally recognized standards and certifications.

 

 ASNT (American Society for Nondestructive Testing)

ASNT is a leading global organization that sets standards for nondestructive testing (NDT), known in Portuguese as the American Society for Nondestructive Testing. Founded in 1941, ASNT is dedicated to promoting the dissemination of technical knowledge and ensuring excellence in NDT through publications, conferences, training, certification programs, and e-books. ASNT offers a variety of certifications for NDT professionals, validating their competence and ability to perform these tests accurately and reliably. According to its standards, candidates must achieve at least 80% on evaluations to obtain certification. Among the most well-known certifications are NDT Level I, II, and III, which cover from entry-level technicians, inspection technicians, inspection engineers, to materials science engineers. These certifications are highly valued in the industry, especially in sectors such as manufacturing, oil and gas, aerospace, construction, and others where structural integrity and safety are crucial.

 

In addition to certifications, ASNT publishes technical standards and guidelines that are widely adopted and respected globally. The organization also promotes continuous research and development in the field of NDT, contributing to the evolution and innovation of inspection techniques.

 

 PCN (Personnel Certification in Non-Destructive Testing)

PCN is an internationally recognized certification program for nondestructive testing professionals. Managed by the British Institute of Non-Destructive Testing (BINDT), PCN provides a comprehensive framework for certification in a variety of NDT methods, such as ultrasound, radiography, magnetic particles, liquid penetrants, and eddy currents. To obtain this certification, candidates must achieve at least 70% on the exams. The PCN certification program is known for its rigor and adherence to international standards, ensuring that certified professionals have the skills and knowledge necessary to perform high-quality inspections. PCN certification is widely adopted in various countries and is a reliable indication of a professional's competence in NDT.

Additionally, BINDT offers continuous support for professional development, including training opportunities, educational resources, and industry events. This ensures that certified professionals stay updated with the latest innovations and best practices in the field of NDT.

 

 ISO (International Organization for Standardization)

 ISO is an international organization that develops and publishes standards in various areas, including quality management, safety, and environmental management. Founded in 1947, ISO aims to facilitate international trade and promote innovation and safety through standardization. One of the most relevant standards for the certification of personnel in nondestructive testing is ISO 9712. This international standard establishes requirements for the certification of NDT professionals, defining the criteria for training, experience, and skills necessary to competently perform specific NDT methods. Certification according to ISO 9712 is internationally recognized and widely used to ensure the competence and quality of NDT professionals across various industry sectors, such as energy, construction, automotive, and aerospace. Additionally, ISO 9712 promotes the global harmonization of certification requirements, facilitating the mobility and trust of NDT professionals in different markets and regions.

 The implementation of ISO standards significantly contributes to the continuous improvement of NDT processes, ensuring the structural integrity, safety, and reliability of inspected products and infrastructures.

The table below explores the differences between the three standards:

   

	ASNT	PCN	ISO
Based on	ASNT recommended                            practice + SNT-TC-1A/Employer’s written practice of NDT qualification	ISO 9712 Standard/Scheme Qualification & certification of NDT Personnel	ISO 9712 Standard/scheme qualification & certification od NDT Personnel
Training deliveres by	Employer ASNT NDT Level III or na outside agency	Approved training centre (ATO) by BINDT	Approved certification Body/ Agency per ISO 9712
Examined by	Employer ASNT NDT Level III or an outside agency os ANST	Approved training centre (ATO) by BINDT	Approved Examination Body/Agency per ISO 9712 and certification body
Certification holder	Individual only inside company use as per SNT-TC-1A, internal/External per	Individual	Individual
Certification validity	3 to 5 years	5 years	5 years
Minimum passing score	80%	70%	70%

Now that you know the differences between the three NDT standards, it will be easier to determine which training best suits your goals and profile.
