Aerospace series - Test method for metallic materials - Ultrasonic inspection of bars, plates, forging stock and forgings - Part 3: Reference blocks

This European Standard specifies the requirements for the manufacture, checking and marking of the series of ultrasonic testing reference blocks containing flat bottom holes (FBH) which define the indicated defect size to which reference is made in EN standards.
The application of ultrasonic testing reference blocks containing side drilled holes (SDH) which define an indicated defect size shall be agreed between manufacturer and purchaser.
This standard is applicable to the production of master and standard test blocks to be used when carrying out ultrasonic inspection to the requirements of EN 4050 1 (FBH method).
It is recognized that particular difficulties are encountered with round forging stock and bars due to the wide range of curvatures. For this application, only one block shall be produced to act as both master and standard test block.

EN 4050-3:2012 (E) 4 1 Scope This European Standard specifies the requirements for the manufacture, checking and marking of the series of ultrasonic testing reference blocks containing flat bottom holes (FBH) which define the indicated defect size to which reference is made in EN standards. 2 Generality The application of ultrasonic testing reference blocks containing side-drilled holes (SDH) which define an indicated defect size shall be agreed between manufacturer and purchaser. This standard is applicable to the production of master and standard test blocks to be used when carrying out ultrasonic inspection to the requirements of EN 4050-1 (FBH method). It is recognised that particular difficulties are encountered with round forging stock and bars due to the wide range of curvatures. For this application, only one block shall be produced to act as both master and standard test block. 3 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

5.2 Flat bottom holes standards Flat bottom holes in the master test blocks shall be used to calibrate standard test blocks. The master test blocks shall have FBH at different metal paths to suit the product range to be inspected. It shall be ensured however that there is sufficient number with a minimum of three different metal paths to accurately produce the required distance/amplitude curve (see 5.4.2.2). 5.3 Manufacture 5.3.1 Material procurement Material for each set of master test blocks shall be obtained from the same cast, forging and heat treatment batch.
