Full title and description

ISO 1053:1975 — Zinc — Determination of copper content — Spectrophotometric method. Specifies two spectrophotometric procedures for measuring copper in high‑purity zinc and zinc alloys (various zinc grades). This product page is for information about the 1975 edition and availability of Russian‑language PDF copies (third‑party translations may exist).

Abstract

The standard defines two spectrophotometric methods applicable to zinc of different purities (examples: Zn 99,995; Zn 99,99; Zn 99,95; Zn 99,5; Zn 98,5). Method A covers copper contents approximately between 0.0005 % and 0.005 %; Method B covers higher copper contents (approximately 0.0025 % to 0.1 %). It specifies principle, reagents, apparatus, sampling, test procedure, expression of results and reporting.

Scope

This standard specifies two spectrophotometric methods for determining copper in zinc and certain zinc alloys. It is intended for quality control and chemical analysis of zinc of different commercial purity grades. The specified methods cover very low copper concentrations (sub‑ppm to a few ppm) and higher trace levels up to about 0.1 % copper, with guidance on reagents, apparatus, sample preparation, calibration and calculation of results.

Key topics and requirements

• Two spectrophotometric procedures (different sensitivity ranges) for copper determination in zinc.
• Scope of applicability by zinc purity grades (examples: Zn 99,995 → Zn 98,5).
• Required reagents and chemicals and recommended reagent grades.
• Apparatus and spectrophotometer wavelength/conditions for the colorimetric measurement.
• Sampling, sample dissolution or digestion and preparation steps to avoid contamination.
• Calibration, limit of detection/quantification guidance for each method and calculation/reporting of results.
• Quality control and procedural notes to minimise interferences in spectrophotometric measurement.

Typical use and users

Used by metallurgical laboratories, zinc producers and refiners, incoming/outgoing quality control teams, materials testing laboratories, research laboratories working with zinc and zinc alloys, standards bodies and compliance auditors. Typical uses include purity verification, process control and acceptance testing of zinc metal or alloy batches.

Related standards

Standards covering related analyses and methods for zinc and zinc alloys (examples): other ISO methods for elemental determination in zinc and alloys (e.g., ISO 1055 / ISO 1976 and similar ISO standards for zinc/alloy chemical analysis). National equivalents or similar methods may exist (historical national publications referenced to ISO methods).

FAQ

Q: What is this standard?

A: ISO 1053:1975 is an International Standard that defined spectrophotometric methods for determining copper content in zinc and certain zinc alloys (1st edition, published June 1975).

Q: What does it cover?

A: It covers two spectrophotometric procedures for different copper concentration ranges and provides requirements for reagents, apparatus, sampling, test procedure, calibration, expression of results and reporting for zinc of various purity grades.

Q: Who typically uses it?

A: Metallurgical and analytical laboratories, zinc producers and refiners, QA/QC personnel, materials testing labs and researchers involved in zinc chemistry and alloy quality control.

Q: Is it current or superseded?

A: The ISO bibliographic record shows the 1975 edition as withdrawn. The ISO entry does not list a direct replacement number; in practice users should consult current ISO records or national standards bodies for up‑to‑date test methods or newer standards that cover copper determination in zinc.

Q: Is it part of a series?

A: It is one of several ISO standards dealing with chemical analysis of zinc and zinc alloys (other ISO documents from the same technical committee cover related determinations). It is identified by the base number 1053 within ISO’s standards catalog for metal analysis.

Q: What are the key keywords?
