Training and Experience requirements
Picture this: ASNT's SNT-TC-1A is like a cookbook for Magnetic Particle Testing (MT) chefs. It tells you the recipe to become a certified NDT expert, but each level comes with its own list of ingredients and cooking time!
Level I: The MT Apprentices
Classroom Training: A dash of 12 hours to learn the basics
On-the-Job Training (OJT): 70 hours of seasoning, stirred under a mentor's watchful eye
Level II: The MT Sous Chefs
Classroom Training: Add 20 hours of culinary wisdom (including the 12-hour appetizer from Level I)
On-the-Job Training (OJT): Whip up a total of 210 hours of experience (including the 70-hour entrée from Level I)
Remember, our ASNT cookbook may not be the only one in town. Some kitchens follow different recipes (like ISO 9712 or EN 473), so always check the menu at your workplace to make sure you're cooking up the right qualifications!
And like any good chef, you'll need to pass some taste tests (written and practical exams) to prove your skills. For the elite MT Master Chefs (Level III), there are also secret ingredients (education and experience prerequisites) to conquer before attempting the final culinary showdown (Level III examination)!
And now the serious way:
The ASNT Recommended Practice No. SNT-TC-1A provides guidelines for the training and qualification of nondestructive testing personnel, including Magnetic Particle Testing (MT). The requirements for each level in terms of classroom training and on-the-job training (OJT) hours are as follows:
Classroom Training: Minimum of 12 hours
On-the-Job Training (OJT): Minimum of 70 hours
Classroom Training: Minimum of 20 hours (including the 12 hours from Level I)
On-the-Job Training (OJT): Minimum of 210 hours (including the 70 hours from Level I)
The education and experience requirements for Level III certification in Magnetic Particle Testing (MT) according to ASNT Recommended Practice No. SNT-TC-1A are as follows:
If the candidate holds a degree in engineering or a physical science:
A minimum of one year of experience in nondestructive testing (NDT) in an assignment comparable to that of a Level II in the applicable test method (MT, in this case).
If the candidate has completed two years of college or technical school in engineering or a physical science:
A minimum of two years of experience in NDT in an assignment comparable to that of a Level II in the applicable test method.
If the candidate has completed high school or equivalent:
A minimum of four years of experience in NDT in an assignment comparable to that of a Level II in the applicable test method.
In addition to training hours, candidates must meet other requirements, such as passing written and practical examinations, to become certified at each level. Level III candidates must also meet specific education and experience prerequisites before attempting the Level III examination.
Please note that these are the minimum recommended hours for classroom training and OJT as per ASNT SNT-TC-1A guidelines. The specific requirements may vary depending on the organization or certification scheme. For instance, some organizations might follow the ISO 9712 or EN 473 certification schemes, which have different criteria for these certifications.
