SIST EN 3890:2004

SIST EN 3890:2004 is the Slovenian adoption of EN 3890:2001 for aerospace filler metal. It specifies the requirements for steel FE-WM1502 (X11CrNiMoVN12-3) used as filler metal for welding in aerospace applications.

What does SIST EN 3890:2004 specify?

SIST EN 3890:2004 specifies the requirements for a welding filler metal identified as steel FE-WM1502 (X11CrNiMoVN12-3) for aerospace applications. It is a material standard, so it focuses on the identity of the product, how it is made, how it is supplied, and which inspection and qualification rules apply.

The document is organized around:

• scope and normative references
• material designation and chemical composition
• melting method, product form, production method, and dimensions
• technical specification and delivery condition
• characteristics, inspection items, notes, and product qualification

The standard uses EN 3879 for detailed filler-metal technical requirements and EN 2043 for product qualification.

What are the key requirements of SIST EN 3890:2004?

The standard defines a specific aerospace filler metal and then ties most detailed controls to referenced aerospace material rules. In practice, that means producers and purchasers can use one document to identify the product, check how it must be made, and see which inspections and qualification steps apply.

• Material designation and chemistry - The standard names the material as FE-WM1502 (X11CrNiMoVN12-3) and gives a chemical composition table. For users, this is the basis for ordering, traceability, and verifying that the product matches the intended alloy.
• Melting method - Clause 3 requires the material to be air melted. This matters because the melting route is part of the defined material condition and therefore part of acceptance.
• Product form and production route - Clauses 4.1 to 4.3 specify filler wire and filler rods produced by cold drawing, with controlled dimensions. That tells manufacturers what forms are covered and what production route they must follow.
• Technical specification - Clause 5 points to EN 3879. In practice, EN 3879 carries the detailed technical rules, so this standard works as the grade-specific identifier and EN 3879 provides the broader welding filler-metal framework.
• Delivery condition - Clauses 6.1 and 6.2 require the filler metal to be supplied cold drawn and annealed with delivery condition code U. Buyers and quality teams use this to check that the supplied condition matches the order.
• Use condition - Clause 7 states the use condition as the delivery condition. That links the supplied state directly to the intended use state, which helps avoid ambiguity in procurement and welding preparation.
• Characteristics and inspection items - The characteristics section lists property and inspection headings such as proof stress, tensile strength, elongation, hardness, bending, impact strength, external defects, residual stress, internal defects, batch uniformity, marking inspection, and dimensional inspection. For practice, this means the product is controlled not only by chemistry and supply condition but also by inspection and material consistency.
• Product qualification - Clause 100 points to EN 2043 and says the qualification programme is to be agreed between manufacturer and purchaser. This matters when the material is being approved for aerospace use and both sides need a defined qualification plan.

What terms does SIST EN 3890:2004 define?

• FE-WM1502 - The material designation used for the specified aerospace welding filler metal.
• X11CrNiMoVN12-3 - The steel grade designation associated with FE-WM1502.
• Filler wire - A wire form of welding filler metal covered by the standard.
• Filler rods - A rod form of welding filler metal covered by the standard.
• Air melted - The required melting method for the material.
• Cold drawn - The production method used to make the filler metal.
• Delivery condition code U - The code used for the specified supplied condition.
• Product qualification - The approval process for the product under EN 2043.

Who uses SIST EN 3890:2004?

SIST EN 3890:2004 is used by aerospace materials manufacturers, welding filler-metal producers, purchasers, quality managers, and test laboratories. They use it to specify the alloy, control production, verify delivery condition, and plan qualification and inspection for welding applications.

It is also relevant for organizations that accept aerospace materials against a standard, because it gives the reference points for chemistry, form, production route, and inspection.

What changed in SIST EN 3890:2004 from the previous edition?

SIST EN 3890:2004 is identical to EN 3890:2001.

Which standards are used with SIST EN 3890:2004?

• EN 2043 - Provides the general requirements for semi-finished product qualification, which the standard uses for product qualification.
• EN 3879 - Provides the technical specification for aerospace filler metals for welding, including the detailed inspection and defect requirements referenced throughout the standard.
• EN 4258 - Gives the general organization of aerospace metallic material standards and the links between types of EN standards.
• EN 4500-5 - Gives the drafting and presentation rules for aerospace steel material standards.

What does the SIST EN 3890:2004 document contain?

The document contains the material designation for FE-WM1502 (X11CrNiMoVN12-3), a chemical composition table, and entries for melting method, product form, production method, dimensions, delivery condition, and delivery condition code. It also contains a characteristics section that organizes the controlled properties and inspection items used for acceptance and qualification.

Several items in the characteristics area are cross-referenced to EN 3879, including defect checks, residual stress, batch uniformity, marking inspection, and dimensional inspection. The final qualification line points to EN 2043 and notes that the qualification programme is agreed between manufacturer and purchaser.
