SIST EN 10205:2025/oprA1:2026
(Amendment)Cold reduced tinmill products - Blackplate
- Abstract
This document specifies requirements for blackplate product in the form of coils intended for direct use and mostly for the production of electrolytically zinc coated plate, or coils electrolytically coated with either tin (tinplate) or chromium/chromium oxide (ECCS or ECCS-RC).
Blackplate can be a single or double reduced product and is specified in nominal thicknesses that are multiples of 0,005 mm from typical 0,10 mm up to 0,60 mm.
This document applies to coils in nominal minimum widths of 600 mm.
In addition to this document, the general technical delivery conditions of EN 10021 apply.
NOTE Standard width coils for specific uses, e.g. tab stock, can be slit into narrow strip for supply in coil form.

SIST EN 10205:2025/oprA1:2026 is a draft amendment for cold reduced tinmill products called blackplate. It modifies EN 10205:2024 and keeps the focus on blackplate coils used directly or as feedstock for electrolytically zinc coated plate, tinplate, or chromium/chromium oxide coated ECCS or ECCS-RC. It is aimed at producers, processors, testers, and buyers who need a common basis for specifying product form, dimensions, delivery conditions, and dispute testing.
What does SIST EN 10205:2025/oprA1:2026 specify?
SIST EN 10205:2025/oprA1:2026 specifies a change to the blackplate standard EN 10205:2024. The underlying standard covers blackplate supplied in coils, mainly for direct use and for making electrolytically zinc coated plate, tinplate, or ECCS or ECCS-RC.
The scope in EN 10205:2024 is limited to coils with nominal minimum widths of 600 mm and nominal thicknesses that are multiples of 0,005 mm, with typical thicknesses from 0,10 mm to 0,60 mm. EN 10021 applies alongside the blackplate requirements.
The amendment itself is organized very simply:
- European foreword
- Clause 1 - Modification to Clause A.1, General
What are the key requirements of SIST EN 10205:2025/oprA1:2026?
SIST EN 10205:2025/oprA1:2026 matters mainly because it defines what blackplate is covered and how a tensile test dispute is handled. For a user, the practical questions are whether the material format fits the line, which coating route it will feed, and which test method settles disagreements.
- Coil form only - The blackplate covered by EN 10205:2024 is supplied in coils. In practice, this means the standard is for continuous strip supply, not sheet cut to length.
- Direct use and coating feedstock - The product is intended either for direct use or for further processing into electrolytically zinc coated plate, tinplate, or ECCS or ECCS-RC. This matters when ordering material for packaging and coating lines.
- Single or double reduced product - Blackplate can be single reduced or double reduced. In practice, the reduction state affects the final product condition and therefore how it will behave in later forming or coating steps.
- Thickness control - The scope covers nominal thicknesses that are multiples of 0,005 mm, with typical values from 0,10 mm to 0,60 mm. This gives buyers and suppliers a defined basis for ordering and inspection.
- Minimum width - The standard applies to coils with nominal minimum widths of 600 mm. For procurement, this sets the lower size boundary for products covered by the standard.
- General delivery conditions - EN 10021 applies in addition to the blackplate requirements. This means general rules for steel product delivery remain part of the commercial and technical framework.
- Dispute tensile testing - Clause A.1, General, is amended so that in cases of dispute the tensile test method of Annex D is the reference method. This matters when test results are challenged and one method must be used to settle acceptance.
What terms does SIST EN 10205:2025/oprA1:2026 define?
- blackplate - Cold reduced tinmill product in coil form used directly or as substrate for later coating.
- tinplate - Coil electrolytically coated with tin for packaging and related uses.
- ECCS - Coil electrolytically coated with chromium or chromium oxide.
- ECCS-RC - The chromium/chromium oxide coated form named in the scope alongside ECCS.
- single reduced - A blackplate condition produced with one reduction step, used to describe the product state.
- double reduced - A blackplate condition produced with two reduction steps, used to describe a different final strip condition.
- EN 10021 - The general technical delivery conditions that apply together with EN 10205:2024.
Who uses SIST EN 10205:2025/oprA1:2026?
SIST EN 10205:2025/oprA1:2026 is used by steel producers, tinmill product manufacturers, coating operations, and packaging material converters. It also matters to buyers, quality managers, and laboratories that order, inspect, or test blackplate coils.
In practice, these users rely on the standard when they:
- specify coil dimensions and reduction state
- buy material for tinplate, ECCS, or electrolytically zinc coated plate production
- check delivery conditions against a common steel product basis
- resolve tensile test disputes using the agreed reference method
What changed in SIST EN 10205:2025/oprA1:2026 from the previous edition?
SIST EN 10205:2025/oprA1:2026 modifies EN 10205:2024. The change shown in the amendment is in Clause A.1, General, where the wording on dispute tensile testing is replaced so that the tensile test method of Annex D is stated as the reference method.
Which standards are used with SIST EN 10205:2025/oprA1:2026?
- EN 10021 - Applies as the general technical delivery conditions alongside the blackplate requirements.
What does the SIST EN 10205:2025/oprA1:2026 document contain?
The document is short and focused. It contains a European foreword and one modification clause that revises Clause A.1, General, in EN 10205:2024.
The practical content is a wording change for tensile test disputes. That change keeps Annex D as the reference tensile test method, which matters when product acceptance depends on a contested test result.
The rest of the document background shows the standard context for blackplate coils used in packaging-related steel products. For readers, the useful outcome is a clearer dispute-testing rule within the existing blackplate standard.
