الزامات استاندارد SNT-TC-1A انجمن تستهای غیر مخرب امریکا(ASNT) برای تست ذرات مغناطیسی

Recommended hours ofinstruction 

According to SNT-TC-1A

         A*            B* 

Level I                                total    12             8

 Level II                               total      8             4

*A   high school graduate or equivalent

*B   completion with passing grades of at least two years of engineering or science study at a university, college or technical  school  this is a progressive training course; i.e., consideration as level I is based on satisfactory completion of the level I training course; consideration as level II is based on satisfactory completion of both level I and II training courses.

Topics in the training outline may be deleted or expanded to meet the employer's specific applications or for limited certification and may be accompanied by a corresponding change in training hours.

 Recommended hours of instruction should be considered as a minimum requirement, regardless of training course topic changes.
