Welding. Determination of Ferrite Number (FN) in austenitic and duplex ferritic-austenitic Cr-Ni stainless steel weld metals1 Scope This document specifies the method and apparatus for: the measurement of the delta ferrite content, expressed as Ferrite Number (FN), in largely austenitic and duplex ferritic austenitic stainless steel1 weld metal through the attractive force between a weld metal sample and a standard permanent magnet; the preparation and measurement of standard pads for manual metal arc covered electrodes. The general method is also recommended for the

spectral transmittance of filters and frames

joints and parts used in refrigerating systems and heat pumps as described in EN 378

it is convenient to use a standard gas mixture containing a suitable known amount of each of the gas components to be in a similar ratio to the common ratios of the gases extracted from transformer oils
