AWS A4.4M PDF
This standard describes methods for sample preparation and analysis for determination of total moisture content and other sources of hydrogen measured as water from welding fluxes and electrode coverings. The methods of analysis are suitable for shielded metal arc electrode coverings and submerged arc fluxes.
It is not the intent of this standard directly herein to classify arc welding electrodes or fluxes as to the total water content measured. However, it is intended that this standard be used as the standard test method for classification purposes to be referenced in individual filler metal specifications prepared by the AWS Committee on Filler Metals and Allied Materials and its subcommittees.
In addition to its use for classification purposes, it is intended that this standard be used for quality conformance testing of arc welding electrodes and fluxes. It is recommended that this standard be used for development and reporting research results so that the results may be directly compared with results from other laboratories.
This standard does not purport to address the safety and health precautions, if any, associated with the use of these procedures prescribed in this standard. It is the responsibility of the user of these procedures to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
