C(95%) = (t x sd)/ n The half-width confidence interval, where t is the appropriate Student's t value, sd is the interlaboratory standard deviation, and n is the number of acceptable mean values. For further information regarding the confidence interval for the certified value, see ISO Guide 35:989 section 4. Certification Process: The requirements of ISO Guide 3, ISO Guide 34, ISO Guide 35, and ASTM Standard Guides E 74 and E 83 were followed for the preparation of this reference material and certificate of analysis. This is a reference material as defined by ISO Guide 30. Analysis: Chemical analyses were made on chips prepared by a lathe from the certified portion of the bars in accordance with ASTM Standard Practice E 806. The laboratories participating in the testing normally followed the requirements of ISO Guide 5. The individual values listed above are the average of each analyst's results. Methods of analysis used were a combination of ASTM Standard Methods E 350, E 353, and 09 plus additional ICP and AA spectrometric methods. Outliers: Some outlying data was excluded from the data listed above due to technical assessment of the cooperating laboratories and statistical evaluation. Homogeneity: This Reference Material was tested for homogeneity using ASTM Standard Practice E 86 and found acceptable.

McIntosh Validity statement: ISO Guide 3 requires that a validity period statement be included in the certificate of analysis. This Reference Material is valid for 0 years from the certificate date. Source: This material was produced by Avesta Sheffield Bar Company, Richburg, South Carolina. The material was made in an electric arc furnace and cast into ingots. The bar stock was hot rolled and annealed. Available Form: This Reference Material is available in the form of a disc, approximately 38 mm (.50") in diameter and mm (0.50") thick. Use: This Reference Material is intended for use in optical emission and x-ray spectrometric methods of analysis. The entire depth of the disc may be used. Caution: As with any bar material, avoid optical emission spectrometric burns in the center of the disc (5 mm radius), as some segregation may be present. Sample Preparation: For best analytical results, use the same method for preparing the analytical surface on all reference materials as you use for production specimens. Avoid overheating the disc during surface preparation. Safety Notice: A Material Safety Data Sheet (MSDS) is not required for this material. This material will not release or otherwise result in exposure to a hazardous chemical, under normal conditions of use.
