on October 30, 1999.

Replaces the approved standard NF A 04-310 dated October 1991.

Correspondence The European standard EN 10228-4:1999 has the status of French standard.

Analysis This document defines the procedures relating to ultrasonic testing of austenitic and

austenitic-ferritic stainless steel forgings. It specifies two control methods and for

each method sets up the quality classes and the acceptance limits.

Descriptors Technical International Thesaurus: forgings, stainless steels, austenitic steels,

ferritic steels, nondestructive tests, inspection methods, defects, acceptability, limits,

quality classes, orders: sales documents.

Modifications With respect to document replaced, general revision of the document, introduction of

the reflectivity diagram method, conditions of use of transverse wave probes.

being prepared.

French standards having the same scope, but which will prove to be non identical, are as follows:

NF A 09-310 Non-destructive testing — Ultrasonic testing — Calibration blocks types A and B

A 09-315 Non-destructive testing — Ultrasonic testing — Methods of use of calibration blocks types A and B
