26.1 The precision of this test method is based on an interlaboratory study conducted in 2015. Eleven laboratories tested 30 different samples, at both high and low composition levels, for up to 32 elements. Every test result represents an individual determination. All participants provided test results in triplicate. Practice was followed for the design and analysis of the data
Significance and Use | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
5.1 This test method for the analysis of aluminum and aluminum alloys is primarily intended to test material for compliance with The Aluminum Association Inc.5 registered composition limits or other specified composition limits for aluminum and aluminum alloys. 5.2 It is assumed that all who use this test method will be trained analysts capable of performing common laboratory procedures skillfully and safely, and that the work will be performed in a properly equipped laboratory. 5.3 This is a performance-based test method that relies more on the demonstrated quality of the test result than on strict adherence to specific procedural steps. It is expected that laboratories using this test method will prepare their own work instructions. These work instructions should include detailed operating instructions for the specific laboratory, the specific reference materials employed, and performance acceptance criteria. |

1. Scope | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
1.1 This test method describes the inductively coupled plasma atomic emission spectrometric analysis of aluminum and aluminum alloys for the following elements:
1.2 This test method has only been interlaboratory tested for the elements and ranges specified. It may be possible to extend this test method to other elements or different composition ranges if method validation, which includes evaluation of method sensitivity and precision and bias (as described in Section 14), is performed. Additionally, the validation study must evaluate the acceptability of sample preparation methodology using reference materials and/or spike recoveries. The user should carefully evaluate the validation data against the laboratory’s data quality objectives. Method validation of scope extensions is also a requirement of ISO/IEC 17025. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 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 and health practices and determine the applicability of regulatory limitations prior to use. Safety hazard statements are given in Section 10 and specific warning statements are given in Sections 15, 17, 18, 19, 20 and 21. |
