Overview

EN 13615:2001 is a CEN (European) standard that defines atomic spectrometric methods for the analysis of ingot tin, specifically for tin grades 99,90 % and 99,85 %. The standard covers sample preparation, reagent and calibration requirements, instrument performance checks and the calculation and reporting of impurity element contents using Atomic Absorption Spectrometry (AAS) or Inductively Coupled Plasma Atomic Emission Spectrometry (ICP‑AES). It is written for experienced analysts familiar with atomic spectrometry and tin metallurgy.

Key topics and requirements

• Scope and principle: Dissolution of an ingot tin test portion in a mixture of hydrochloric and nitric acids with tartaric or citric acid, followed by measurement of impurity concentrations by AAS or ICP‑AES.
• Sample preparation: Specific guidance for preparing test and blank solutions to ensure matrix matching and minimize interferences.
• Reagents and standards: Use of analytical‑grade reagents, preparation of acid mixtures and detailed preparation of metal standard solutions for calibration (e.g., Sb, Pb, Cu, Bi, Cd, Zn, Fe, As, Ni, Ag, Al, In).
• Calibration and CRM: Calibration curves prepared from matrix‑matched standards and the use of Certified Reference Materials (CRM) where available.
• Instrument performance: Normative annexes specify performance checks for AAS (Annex A) and ICP‑AES (Annex B), including operational setup, wavelengths/bandpass selection and recommended verification procedures (based on ISO 7530‑1 where applicable).
• Precision and reproducibility: Interlaboratory reproducibility is element‑dependent; the standard includes results from AAS and ICP‑AES interlaboratory tests and guidance for evaluating method precision.
• Reporting: Mandatory items for the test report (sample identification, reference to EN 13615, experimental results, date, and observations).

Applications and who uses it

EN 13615:2001 is practical for:

• Laboratories performing chemical analysis of tin ingots for quality control and acceptance testing.
• Tin producers and smelters verifying compliance with commercial tin grades (99.90 % and 99.85 %).
• Procurement and inspection bodies requiring traceable impurity data for lead, copper, antimony, bismuth, cadmium, zinc, iron, arsenic, nickel, silver, indium, aluminium and other trace elements.
• Metallurgical R&D groups and third‑party testing labs implementing validated AAS or ICP‑AES procedures for tin alloys.

Benefits include improved traceability of impurity measurements, consistent sample preparation and validated instrument performance checks to ensure reliable ingot tin analysis.
