Full title and description

ISO 1055:1975 — Zinc and zinc alloys — Determination of iron content — Spectrophotometric method. This International Standard specifies a spectrophotometric analytical procedure for determining low levels of iron in certain zinc alloys and die-castings.

A Russian-language electronic copy (marketed as "St ISO 1055-1975 rus" or "Ст ISO 1055-1975 rus") is offered by third‑party standards distributors as a PDF reprint/translation for users who need the standard text in Russian.

Abstract

The standard defines a spectrophotometric method applicable to zinc alloys such as Zn Al 4, Zn Al 4 Cu 1, Zn Al 4 Cu 3 and Zn Al 11 Cu 1, and to die‑castings made from these alloys. It is intended for determination of iron contents in the approximate range 0.01 % to 0.08 %.

Scope

The scope covers a laboratory spectrophotometric procedure for measuring iron at low concentrations in selected zinc alloys and die‑casting materials. The method gives reliable results for iron contents between about 0.01 % and 0.08 % and is formulated for the alloy types listed in the standard (examples: Zn–Al and Zn–Al–Cu compositions). The procedure includes sample preparation, reagents, instrument considerations, calibration and the applicable measurement range.

Key topics and requirements

• Spectrophotometric determination of iron in zinc and zinc alloys.
• Specified alloy types to which the method is applicable (Zn Al 4, Zn Al 4 Cu 1, Zn Al 4 Cu 3, Zn Al 11 Cu 1).
• Analytical range: approximately 0.01 % to 0.08 % iron.
• Details on sample dissolution/preparation, reagents and calibration practices (as concise method steps in the 1975 text).
• Intended for laboratory quality control and metallurgical analysis of die‑cast components and alloy melts.

Typical use and users

Primary users are metallurgical and chemical testing laboratories, quality control departments in zinc die‑casting and alloy‑production facilities, and standards/consulting organizations performing material certification. Where Russian language documentation is required, suppliers of standards provide a Russian PDF reprint/translation for purchase.

Related standards

ISO 1055:1975 is part of a cluster of ISO standards addressing analysis of zinc and related elements (nearby numbers include ISO 1053:1975 — determination of copper, and ISO 1054:1975 — determination of cadmium). The ISO 1055 text was adopted or republished in national catalogs (for example as DIN ISO 1055) and later national/European documents have replaced some historical methods. Check national catalogs for any current replacements or updated methods used in practice.

FAQ

Q: What is this standard?

A: ISO 1055:1975 is an International Standard that specifies a spectrophotometric method for determining iron content in specified zinc alloys and die‑castings.

Q: What does it cover?

A: It covers sample preparation, reagents, measurement procedure and calibration for the spectrophotometric determination of iron in selected zinc alloys, with an analytical range of about 0.01 %–0.08 % iron.

Q: Who typically uses it?

A: Metallurgical laboratories, die‑casting manufacturers, quality‑assurance and materials testing organizations that need to quantify low iron levels in zinc alloys. Suppliers of standards also market translated PDF copies (e.g., Russian) for customers requiring the standard text in other languages.

Q: Is it current or superseded?

A: The ISO record shows ISO 1055:1975 as withdrawn. Users should verify whether a newer ISO method or a national/EN replacement now applies in their jurisdiction; national catalogs (for example DIN) and ISO's catalogue note the withdrawal and any successor documents.

Q: Is it part of a series?

A: Yes — ISO 1055:1975 sits among other ISO standards addressing analytical methods for zinc and related determinations (neighbouring numbers include ISO 1053 and ISO 1054 from the same era). These related documents address determination of copper, cadmium and similar analyses.

Q: What are the key keywords?

A: Zinc, zinc alloys, iron determination, spectrophotometric method, die‑casting, ISO 1055, analytical chemistry, Russian PDF.
