ANSI ASNT CP 189 PDF

Maukora For an individual to become certified in multiple test methods, each method must be represented by method-specific training, experience and examinations. Level III examinations also require a procedure be prepared for the practical exam. Of course, the most fundamental difference to remember is that CP is a standard that details minimum requirements, while SNT-TC-1A is a set of recommendations qnsi an employer-based program. Although both routes to certification have attributes and detriments they do ensure adequate coverage of all industrial needs with flexible options to address specific requirements.

The intent was to produce a new document that provided strict requirements rather than simply guidelines. When a company decides to follow CP , they must accept all the requirements of that standard, with little or no adjustment or leeway and the relevant training requirements!

As to where it is used, well that is dictated by client and contract specifications I would guess, but most likely boiler and pressure vessel type fabrications! By supermoto Date Thanks for your response. I know the reason for creating it and being more stringent as a standard an not a recommended practice.

Sounds like there may not be a specific code or standard that requires it other then customer may require it. This is from a paper submitted for the15th World Conference on Non-Destructive Testing October in Rome: "I think that you will agree training would be beneficial for visual test applications, but is certification necessary?

Each category specifies visual applications and is available at levels 1 or 2 with specific criteria pertaining to eligibility of trainers and prospective level 3 persons. Not all code or standards require certification but how else do you assess the competence of test personnel? An age-old phrase of justification is that of "continued satisfactory performance" but what does this mean?

Is this a quantifiable value or a misnomer of accuracy? Surely by virtue of demonstrating continuous performance by an internal or external means of assessment, automatically achieves traceability and quantification. But this approach is little short of the certification process advocated by many as costly and unnecessary. Certification schemes are available to operate as company internal quality measures with internal or external moderation.

Certification in accordance with EN and ISO is differs from those previous by classification as central certification in a similar vein to college examination bodies. Although both routes to certification have attributes and detriments they do ensure adequate coverage of all industrial needs with flexible options to address specific requirements. Should you require any further guidance on any of the points mentioned in this paper please contact Lavender International NDT Ltd.

Both exist as parallel programs available for a contractor to specify and a sub contractor to adopt. It differs significantly in several areas. A brief list of some of the major differences below: 1. This cannot be reduced in rigidity to suit company requirements dictated by CP Again it must be approved by the Level III.

Vision Requirements - The vision requirements for near vision acuity are more stringent in CP requiring acuity to read the Jaeger 1 instead of Jaegar 2. Levels of qualification - There are 5 levels of qualification instead of 3 the additional 2 being "Instructor" and "Trainee".

Level III examinations also require a procedure be prepared for the practical exam. Again this is not a comprehensive list of the differences, but simply the "major" fundamental differences in the concepts By far the most important fundamental difference is in the concept that CP is a national standard and must be treated as a minimum requirement not simply a set of guidelines which may be altered This is reflected throughout the 2 documents by the choice of verbs used CP uses "shall "throughout to emphasize a mandatory requirement", whereas SNT - TC - lA uses the verb "should" to emphasize a recommendation" However, the owner, customer should be aware of the differences between a set of recommended guidelines and an actual ANSI approved by consensus American National standard in order to make the right choice in choosing between the 2 parallel certification schemes offered by ASNT Clear as Oktoberfest Beer eh?
