Lead Base Battery Alloy Block (0.5% Sn)

The material for this sample was prepared by Castings Technology International (CTI), using a special method of casting known to provide material of uniform composition in a form suitable for use as calibration reference materials in optical emission spectroscopic and XRF analysis. Representative samples were examined spectroscopically and found to give reproducible results. This sample is in the form of chill-cast rectangular blocks approximately 50 mm x 50 mm x 20 mm thick with a single chilled working face. Spectroscopic reproducibility has been shown to be reliable to a depth of 15 mm below the original surface of the block. Analysis must be made on the fully ground surface only and the sample should not be used once the thickness has reached 5mm. The sample is also available in bottles of 100g of turnings. This PBRM is classified as a Reference Material (RM) and NOT a Certified Reference Material (CRM) according to the definitions in the International Organisation for Standardisation Guide 30 where they are defined as follows :- Reference Material: Material, sufficiently homogeneous and stable with respect to one or more specified properties, which has been established to be fit for its.
