(Test Method)Standard Test Method for Sampling and Testing for Ash and Total Iron in Steel Mill Dispersions of Rolling Oils
Standard Test Method for Sampling and Testing for Ash and Total Iron in Steel Mill Dispersions of Rolling Oils
SIGNIFICANCE AND USE
5.1 The life cycle and cleanliness of a recirculating steel mill rolling oil dispersion is affected by the amount of iron present. This iron consists mainly of iron from acid pickling residues and iron from attrition of the steel sheet or rolls during cold rolling. In sampling rolling oils for total iron it is difficult to prevent adherence of iron containing sludge to the sample container. Thus, the accuracy of a total iron determination from an aliquot sample is suspect. This practice provides a means for ensuring that all iron contained in a sample is included in the analysis.
5.2 Although less significant, the ash content is still an essential part of the procedure for obtaining a total iron analysis. Generally, the ash will be mostly iron, and in many cases, could be used as a substitute for total iron in determining when to change the dispersion.

SCOPE
1.1 This test method describes a procedure for sampling and testing dispersions of rolling oils in water from operating steel rolling mills for determination of ash and total iron content. Its purpose is to provide a test method such that a representative sample may be taken and phenomenon such as iron separation, fat-emulsion separation, and so forth, do not contribute to analytical error in determination of ash and total iron.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific warning statements, see Sections 7 and 8.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4. Summary of Test Method
4.1 Polyethylene disposable sample bags in a suitable holding device are used to collect representative samples of nonhomoge-
neous dispersions of rolling mill oils in water from an operating mill coolant system.
4.2 The collected sample and disposable bag are analyzed as one for ash and total iron.
4.2.1 Ash content is determined gravimetrically by evaporating all water from the sample bag before heating the residue and bag
in a muffle furnace to a constant weight (Test Method D482).
4.2.2 Total iron content is determined by digesting the iron in the ashed sample and bag in an acidified solution. The iron in the
solution is reduced with stannous chloride and titrated with standardized potassium dichromate.
4.2.3 The ash and total iron contributed by a sample bag alone are determined separately and are subtracted from the values of
bag and sample to obtain the values for the sample alone.
NOTE 1—There are a number of alternative methods available for determining total iron in an ashed solution such as Test Methods D2795 and D1068.
