Full title and description

ISO 1054:1975 — Zinc — Determination of cadmium content — Polarographic method. This International Standard specifies a polarographic analytical procedure for measuring cadmium in specified grades of zinc.

Abstract

The standard defines a polarographic method applicable to zinc grades such as Zn 99,95; Zn 99,5; Zn 98,5 and Zn 98 for cadmium contents between 0,01 % and 0,5 %. It notes limitations where copper content is more than four times the cadmium content. The published document is brief (technical method specification).

Scope

Specifies a polarographic analytical procedure for determining cadmium in selected commercial grades of zinc (high-purity and specified lower purities) when cadmium content lies approximately between 0.01% and 0.5%. The method excludes samples where interfering copper is present at concentrations more than about four times the cadmium level.

Key topics and requirements

• Polarographic titration/measurement technique adapted for zinc matrices.
• Preparation of zinc samples and matrix treatment to enable accurate polarographic determination.
• Calibration and cadmium standard solution preparation for mg-level determinations (specified concentration ranges).
• Limits of applicability and interference notes (especially copper interference and limits of cadmium concentration range).
• Short technical specification (the published document is two pages long and focused on the analytical procedure).

Typical use and users

Used by metallurgical quality-control laboratories, analytical chemists in zinc production and refining, materials testing labs, standards bodies and technical libraries that archive historical analytical methods. Laboratories use it when polarographic determination is the chosen or available method for cadmium in zinc alloys or refined zinc samples.

Related standards

ISO 1054:1975 was the transformation of earlier ISO Recommendation R 1054 (1969) into an International Standard; it sits among a cluster of mid‑1970s ISO methods for trace element determination in zinc (for example ISO 713:1975 and other ISO 1975-series methods addressing lead, iron and other impurities). The ISO catalogue lists ISO 1054:1975 as withdrawn; historic bibliographies and standards collections record its relation to earlier recommendations.

FAQ

Q: What is this standard?

A: ISO 1054:1975 is an International Standard that defined a polarographic method for determining cadmium content in specified grades of zinc.

Q: What does it cover?

A: It covers sample preparation, cadmium standard solutions and the polarographic measurement procedure for cadmium in zinc when cadmium is present between approximately 0.01% and 0.5%, with notes on interfering elements (notably copper).

Q: Who typically uses it?

A: Metallurgical and analytical laboratories in zinc production and refining, materials testing facilities, historical standards collections and regulatory/standards professionals referencing legacy analytical methods.

Q: Is it current or superseded?

A: It is recorded in the ISO catalogue as Withdrawn. ISO’s online record does not show a one‑to‑one current replacement for ISO 1054:1975 in the catalogue entry; several related ISO methods from the same period were also withdrawn without direct replacement.

Q: Is it part of a series?

A: Yes — it is part of a set of mid‑1970s ISO methods for determination of trace elements and impurities in zinc and zinc alloys (documents from ISO/TC 18 addressing lead, cadmium, iron, copper etc.). ISO 1054:1975 was technically identical to the earlier ISO Recommendation R 1054 and replaced that recommendation when published as an International Standard.

Q: What are the key keywords?

A: Zinc; cadmium; polarography; trace analysis; ISO 1054; analytical method; metallurgical testing; withdrawn standard.
