1.0 PURPOSE

The purpose of this procedure is to establish, monitor and implement the Ferrite testing to determine the acceptability of Ferrite contents in the welds of austenitic stainless steel in order to meet project specifications, reference Codes & Standards.

2.0 SCOPE

This test method covers the apparatus and procedure for measuring Ferrite by Ferritoscope – FM P30 (Fischer) or equivalent for non destructive measurement of ferrite contents range of 0 - 80% Fe suitable for Austenitic stainless steel welds.

4.0 PROCEDURE First connect the probe of the analyzer with the arrow aligned to the meter.

Then switch ON the Ferrite meter. Go to APPL NO select FN or %. Select applications standard. Ensure thorough calibration is made to the exact range of ferrite being measured. Now the machine is ready for calibration/use.

5.0 CALIBRATION

Equipment shall be calibrated prior to each use and whenever batteries, probe cable etc. are replaced.

The machine is supplied with two calibration blocks in low and high ranges.

Press ZERO place the probe on BASE then press ENTER.

Now place the probe on the test block range whatever we are going to test on the job.

The test blocks range as; 2.28FN (2.62%), 2.56FN (2.96%), 8.5 FN (9.8%), 9.0FN (10.4%), 9.6FN (11.0%) 33.6 FN (30.2%), 35.0FN (31.0%), 40.0FN (34.2%), 121.5FN (86.1%).

6.0 TEST METHOD

Place the probe on the sample/job to be tested and note the reading on the Ferrite meter.

Precautions:

If grinding is done on the job then epsilon phase may be present leading to erroneous values. So grinding speeds shall be slow.

Ensure a clear surface without any scaling, point marks or grease.

Before testing it is suggested to clan the surface with 10%-20% diluted nitric acid.

Ensure that the probe is away from strong magnetic fields or magnets.

Surface must clean to remove dirt, iron chips, etc

Probe is temperature sensitive so avoid high temperatures.
