I would not contact the customer directly, unless it is your job description to do so. I have run across a couple of engineers that were looking for me to make the call so that if it went wrong they could sit back and let the blame fall on me. Should we talk about their detection sensitivity or their ability to detect discontinuities?
We have no amendments or corrections for this standard. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. This standard is also available to be included in Standards Subscriptions.
ASTM E1417 E1417M-13
Using current equipment and methods, even difficult pieces can be fabricated with precision. File manual for pile welding.
In this case the discontinuity is acceptable as e1417/f1417m-13 as the rounded discontinuities don’t number more than 3 and are less than 2mm in size. Hello Nikhilesh, Keep in mind that penetrant inspection is used to detect discontinuities e1417/e147m-13 easily detected by visual inspection. These terms are not defined in the EN and standards. Power industry guru’s I can hear you grumbling now Although the issues raised are very valid, your Level III is usually the final sign off.
If however the discontinuity is severe enough to be rejected then we call it a defect indication.

Therefore if the procedure is e1417/e4117m-13 terms of discontinuity, and the size limit is 10mm. If I make the acceptance class more stringent my company VP would ‘definitely’ not be happy with zstm. Here are the contents: I had some good learning through this discussion.
Ispitivanje EX opreme nerazornim e4117/e1417m-13 ispitivanja. Liquid Penetrant Report Sample Format. November – Fluorescence vs Phosphorescence. An unethical commercial practice March I belong to a production environment. What you wrote is logical – VT sees the discontinuity either with the unaided eye or with a suitable magnification, but that is taken care as a known factor. Indication sizing In Reply to Amy at A man dedicated to magnetic testing.
I have never used flaw sizing in Aerospace.
While the depth of a discontinuity can not be measured, indication size bleed-back does give some idea as to the extent that the discontinuity extends below the surface. The standard requires you to identify the indication type, not just linear and rounded and evaluate to the Grade specified in the tables. As the voice of the U. Prior to examination, tests should be conducted to ensure that none of the cleaning or examination materials are harmful to the components to be examined.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Basic principles of liquid penetrant inspection. What are the appropriate means of measuring such a flaw?
You are asking good questions. They decide the maximum number of flaws acceptable in Aircraft. Most codes I have read do not use the words defect indication but instead say discontinuity as this denotes a flaw in the material that may or may not render the component unservicable.
ASTM E / EM – 13 Standard Practice for Liquid Penetrant Testing
Visible Dye Penetrant Inspection Process. Djuhera Almir – Ispitivanje penetrantima. Work Item s – proposed revisions of this standard. Please first verify your email before subscribing to alerts. The acceptance standards for these different approaches are bound to be different.
Penetrant Testing Of Aerospace Materials. Indication sizing In Reply to Tim at All I can say is report what you find check it against the maintenance manual for the fleet you are working on and then let the engineers determine acceptability or rejectability for it.
This standard is not included in any packages. Kerstyn Comley and Norman Fleck – Deep penetration and liquid injection into adipose tissue.
Let me elaborate with a sample case: Ducts can be pressure tested up to psig, as needed. The material is not ferromagnetic. Major takeaways from your write-up are the following: Combining values from the two systems may result e1417/e1417m-3 non-conformance with the standard.
I am not sure how much time you have in the aircraft industry but most of the accept reject criteria is laid out in the aircraft maintenance manuals, with limitations being set by structural engineers at the manufacturing companies who through extensive testing determine what is acceptable or not.
