SIST EN 13615:2004 is the Slovenian adoption of EN 13615:2001 for the atomic-spectrometric analysis of ingot tin. It specifies Atomic Absorption Spectrometry (AAS) or inductively coupled plasma Atomic Emission Spectrometry (ICP-AES) methods for determining impurity element contents in tin grades 99,90 % and 99,85 %, and it is written for experienced analysts familiar with atomic spectrometric techniques.
What does SIST EN 13615:2004 specify?
SIST EN 13615:2004 specifies how to measure impurity elements in ingot tin by AAS or ICP-AES. The document is organized as a short method standard with clauses for principle, reagents, apparatus, sampling, procedure, expression of results, and test report, plus two normative annexes for checking instrument performance.
The main text tells the laboratory how to prepare the sample, build calibration solutions, take measurements, and calculate results. The annexes support the method by showing how to verify that the spectrometer is fit for use before analysis starts.
| Annex | What it covers |
|---|---|
| Annex A | Method for checking atomic absorption spectrometer performance |
| Annex B | Method for checking inductively coupled plasma atomic emission spectrometer performance |
What are the key requirements of SIST EN 13615:2004?
SIST EN 13615:2004 requires the sample to be dissolved in hydrochloric acid and nitric acid with tartaric acid or citric acid, then measured by atomic spectrometry. In practice, this means the analyst works in a matched acid matrix so that the tin solution and the calibration solutions behave similarly in the instrument.
Sample preparation and calibration
The method prepares the test solution from a weighed tin sample and also prepares a blank test solution using high purity tin. Calibration solutions are made in the same matrix with high purity tin and standard metal solutions. This matters because matrix matching reduces interference and makes the calibration curve more reliable.
Measurement and calculation
The spectrometer is set up at the wavelengths given in Annex A or Annex B, depending on the instrument type. The standard calls for at least two runs and uses the average of readings from separate runs. The element content is then calculated from the calibration curve after correcting for the blank, and reported as mass percent.
Reference materials and precision
Where a certified reference material (CRM) of similar matrix is available, it is treated exactly like the sample. The document also gives reproducibility results from interlaboratory testing for AAS and ICP-AES. That tells the user what level of between-laboratory variation was observed and helps when comparing results or validating a routine method.
Spectrometer suitability checks
Annex A checks AAS readability, linearity, precision, and minimum stability, and also lists wavelengths for the elements commonly measured in tin-based alloys. Annex B checks ICP-AES calibration graph curvature, background equivalent concentration (BEC), spectral interference, and short- and long-term precision. In practice, these checks confirm that the chosen instrument can produce usable results before the sample series starts.
Reporting
The test report has to identify the sample, cite EN 13615, give the test results, state the test date, and record any relevant observations. This is the information a buyer, quality manager, or audit trail needs to link a result to a specific sample and method.
What terms does SIST EN 13615:2004 define?
SIST EN 13615:2004 uses several technical terms that matter for routine use:
- Atomic Absorption Spectrometry (AAS) - a technique that measures how strongly free atoms absorb light at selected wavelengths.
- inductively coupled plasma Atomic Emission Spectrometry (ICP-AES) - a technique that measures light emitted by elements excited in an inductively coupled plasma.
- Certified reference material (CRM) - a reference sample with known composition used to check that the method behaves correctly on a similar matrix.
- blank test solution - a solution prepared without the sample, used to correct for reagent and preparation contributions.
- calibration curve - the relationship between instrument signal and known element content, used to convert readings into concentrations.
- Background equivalent concentration (BEC) - an ICP-AES performance check that shows how much analyte would give the same signal as the background.
- Relative standard deviation (RSD) - a precision measure used in Annex B to judge short-term stability.
Who uses SIST EN 13615:2004?
SIST EN 13615:2004 is used by experienced analysts in laboratories that test ingot tin for impurity elements. It is also relevant to quality control teams, laboratory managers, and buyers who need a defined analytical method for acceptance testing, batch comparison, or supplier verification.
The standard is especially useful where AAS or ICP-AES is used for tin grades 99,90 % and 99,85 %. Annex B also makes it relevant to laboratories checking tin-based alloys covered by EN 610 when they need to confirm spectrometer performance or assess spectral interference.
What changed in SIST EN 13615:2004 from the previous edition?
SIST EN 13615:2004 is identical to EN 13615:2001.
Which standards are used with SIST EN 13615:2004?
SIST EN 13615:2004 cites EN 610, which provides the ingot tin product definition and the sampling route for obtaining the test sample. Annex A is based on ISO 7530-1:1990 for AAS performance checking.
Annex B refers to ISO/CD 12235-1 and ISO/CD 13204-1 as general guidance for ICP-AES and flame atomic absorption spectrometry. These references support instrument setup and checking rather than replacing the method in EN 13615.
What does the SIST EN 13615:2004 document contain?
SIST EN 13615:2004 contains a dissolved-sample procedure, calibration-solution preparation, spectrometric measurement instructions, and calculation of element contents from calibration curves. It also includes a list of standard solutions for the impurity elements commonly measured in ingot tin.
The document further contains:
- a wavelength list for AAS measurements in Annex A;
- a wavelength list and interference checks for ICP-AES in Annex B;
- performance checks for readability, linearity, precision, stability, BEC, and calibration-graph curvature;
- reproducibility data from interlaboratory testing;
- the required test report items.
