1.2The following elements may be determined using this test method. The test method user should carefully evaluate the precision and bias statements of this test method to determine applicability of the test method for the intended use.
| Element | Quantification Range (%) |
| Aluminum | 0.060–1.40 |
| Boron | 0.002–0.020 |
| Calcium | 0.001–0.003 |
| Copper | 0.010–0.52 |

1.3This 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 quantification ranges provided that method validation is performed that includes evaluation of method sensitivity, precision, and bias as described in this document. Additionally, the validation study must evaluate the acceptability of sample preparation methodology using reference materials or spike recoveries, or both. The user is cautioned to 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.
1.4The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.5This 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. Specific warning statements are given in 8.2.6.3 and safety hazard statements are given in Section 9.
1.6This 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.
