Full title and description

St ISO 1554-1976 rus — Original ISO title: "Wrought and cast copper alloys — Determination of copper content — Electrolytic method". This item refers to the ISO International Standard (Edition 1, 1976) and to available Russian-language editions/translations or national reproductions of that ISO text.

Scope

Applies to the electrolytic determination of copper in a wide range of wrought and cast copper alloys (for example copper‑aluminium, copper‑zinc, copper‑nickel‑zinc and similar commercial alloys). It gives the laboratory procedure from sample dissolution through electrolytic deposition and weighing of deposited copper, and specifies reporting and repeatability requirements. The standard refers high‑purity copper analysis to ISO 1553.

Key topics and requirements

• Principle: dissolution of an accurately weighed sample and electrolytic deposition of metallic copper for gravimetric determination.
• Required reagents and analytical‑grade chemicals (specified acid and supporting solutions) and recommendations for purification of reagents.
• Apparatus: electrolytic cell, rectifier/low‑voltage supply, platinum electrodes (cathode/anode), drying oven and analytical balance with required precision.
• Sampling procedures and sample preparation to ensure representative results.
• Procedure steps, calculation of copper content, expression of results and format of the test report.
• Repeatability and precision limits expected for routine laboratory practice are defined.

Typical use and users

Used by chemical and metallurgical testing laboratories, foundries, quality‑control departments in manufacturers of copper alloys, materials research laboratories and national/institutional standards bodies. Typical applications include material acceptance testing, composition verification, failure investigation and analytical method reference for labs performing copper assays.

Related standards

Closely related to ISO 1553 (electrolytic method references for very high‑purity copper) and other ISO and national standards addressing chemical analysis of copper and copper alloys. Several countries have adopted or published national equivalents or translations of ISO 1554 (examples of national reproductions/adoptions exist).
