SIST EN 4500-006:2026 is the Slovenian standard corresponding to prEN 4500-006:2025, a draft European Standard prepared by CEN for aerospace metallic materials. It sets specific rules for drafting and presenting material standards for filler metals for brazing, so it is used by people who create, review, or apply aerospace material specifications.

What does SIST EN 4500-006:2026 specify?

SIST EN 4500-006:2026 belongs to the EN 4500 series, which gives rules for the drafting and presentation of metallic material standards for aerospace applications. This Part 006 covers the specific rules for filler metals for brazing and shows how a European material standard for that family should be structured.

The document is organized into four main clauses plus a bibliography, with informative annexes that provide completion examples:

• Clause 1 Scope
• Clause 2 Normative references
• Clause 3 Terms and definitions
• Clause 4 Rules for drafting a European standard for aerospace metallic materials
• Bibliography
• Annexes A to E

Annex	What it covers
Annex A	Completion of the title page
Annex B	Completion of the introduction
Annex C	Completion of the scope, normative references, terms and definitions, and requirements
Annex D	Completion of Table 1
Annex E	Completion of the bibliography

In practice, the standard is a drafting rulebook rather than a product specification for one alloy. That means it tells authors what information belongs in a filler metal standard and how to present it in a consistent aerospace format.

What are the key requirements of SIST EN 4500-006:2026?

SIST EN 4500-006:2026 sets the wording and structure to use when writing a filler-metal standard, especially in the title and in Table 1. The most important point for users is that the standard controls how the information is presented, so the resulting material standard can be read and applied consistently across aerospace projects.

Title and identification rules

Clause 4.2 gives the title rules. The material designation is shown in the title, and when an ECISS designation exists it is added in brackets for information. Annex A illustrates how the title page is completed for materials with and without an ECISS designation, which helps drafters present the alloy name in the expected form.

Melting method and product form

Clause 4.2.2 lists the allowed melting descriptors, such as air melted, inert gas melted, vacuum melted, and vacuum arc variants. Clause 4.2.3 lists the form entries and the qualifiers that may be added for forms such as amorphous foil, borided foil, rolled foil, powder, paste, tape, and wire.

This matters because the title and Table 1 must identify how the filler metal was made and what physical form it has. For a buyer or engineer, that is the first cue that the document applies to the right product type.

Chemical composition and Table 1 structure

Clause 4.5.2 requires chemical composition to be written in the EN 4500-001 format and in a defined order of presentation. Clause 4.5 lays out the full structure of Table 1, including material designation, chemical composition, method of melting, form, method of production, further intended processing, limit dimensions, technical specification, dimensional standard, delivery condition, use condition, test samples, test pieces, heat treatment, dimensions concerned, and the inspection and qualification lines.

In practice, this means the standard forces a complete and predictable data set. Anyone drafting or checking a material standard can see where each piece of information belongs.

Delivery condition, use condition, and heat treatment

Clause 4.5.10 gives the delivery condition and heat-treatment entries, using terms such as as manufactured and annealed. Clause 4.5.12 covers the use condition and heat treatment, and Annex D shows how those entries are completed in a worked example.

This matters when the same filler metal may be supplied, stored, or used in different states. Clear condition wording avoids confusion between what is supplied and what is intended for application.

Test and inspection entries

Clause 4.5.19 to 4.5.26 cover the main mechanical and thermal property lines, including tensile, hardness, shear strength, bending, impact strength, and creep. Clause 4.5.28 to 4.5.33 cover marking inspection, dimensional inspection, notes, typical use, and product qualification.

For practice, this section tells the standard writer which performance topics can be built into the material standard and where the corresponding inspection or qualification information belongs.

Normative application of the table

Annex C states that the requirements of Table 1 shall be applied and that the documents listed in Table 1 shall be applied. Annex D then shows how the table is completed in an example for a nickel base braze alloy, including entries for thermal analysis, wettability, porosity, formability of joining metals, and product qualification.

That means Table 1 is not just an illustration. It is the core structure that the resulting material standard has to follow.

What terms does SIST EN 4500-006:2026 define?

For the purposes of SIST EN 4500-006:2026, the terms and definitions from EN 4259 and EN 4500-001 apply. The document also uses several key drafting terms that matter when completing the title and Table 1.

• ECISS designation - A conventional designation that may be shown in brackets after the material designation in the title.
• Material designation - The identifying name or code for the alloy or filler metal being standardized.
• Delivery condition - The state in which the material is supplied, such as as manufactured or annealed.
• Use condition - The state intended for application or service, which may match the delivery condition.
• Reference heat treatment - The heat treatment state used as the reference point for the standard’s requirements.
• Product qualification - The qualification entry that links the product to an agreed qualification programme or referenced qualification standard.
• Marking inspection - The inspection item used to check product marking before acceptance.
• Dimensional inspection - The inspection item used to check that dimensions meet the specified limits.

Who uses SIST EN 4500-006:2026?

SIST EN 4500-006:2026 is used by standards writers, technical committees, and aerospace material specialists who prepare European or national material standards. It is also used by manufacturers of filler metals for brazing, by aerospace suppliers, and by quality and procurement teams that need to read or apply those standards.

In practice, users rely on it when they:

• draft or review a filler-metal standard for aerospace use
• complete a title page, scope, or Table 1
• define composition, form, condition, testing, and qualification entries
• align a product specification with the EN 4500 drafting system
• check marking, dimensional inspection, and product qualification wording

What changed in SIST EN 4500-006:2026 from the previous edition?

SIST EN 4500-006:2026 supersedes EN 4500-006:2024. The foreword states these significant technical changes:

• addition of the missing text in the scope
• addition of line 4.3, Further intended processing, and line 5.2, Dimensional standard, in the body of the document and in Annex D
• addition of introductory sentences to Table 1 in Annex C to make clear that the table is a normative element and that all listed documents shall be applied
• editorial revisions to clarify whether references to other documents or annexes are normative or informative
• restructuring and simplification of the template to achieve a single continuous table

Which standards are used with SIST EN 4500-006:2026?

Standard	Role in SIST EN 4500-006:2026

What does the SIST EN 4500-006:2026 document contain?

The document contains the drafting rules for the title, introduction, scope, references, terms, and the main Table 1 structure used in aerospace material standards. Clause 4 gives the detailed line-by-line template, including composition, melting method, form, production method, dimensions, tests, inspections, notes, typical use, and product qualification.

Annex A gives title-page completion examples, Annex B gives an introduction example, and Annex C shows how the scope and Table 1 are completed in a normative context. Annex D gives a worked Table 1 example for a nickel base braze alloy, including how property checks and qualification entries are presented. Annex E completes the bibliography and shows the related documents that support the drafting system.
