SIST EN 2829:2001

• Abstract:

  This standard specifies a test method to determine the adhesion of coatings by shot peening. It applies to ductile metal coatings, such as cadmium, silver or copper, with a hardness: - inf to 250 HV for a coating thickness between 25 and 250 micro m ; - sup or equal to 250 HV for a coating thickness between 10 and 60 micro m. It shall be applicable whenever referenced.

SIST EN 2829:2001 is a Slovenian aerospace standard from SIST for checking the adhesion of metallic coatings by shot peening. It specifies a test method for ductile metal coatings such as cadmium, silver and copper, and it is used whenever a specification calls for this adhesion check. Engineers, laboratories and buyers use it to decide whether a coating falls within the thickness and hardness ranges covered by the method.

What does SIST EN 2829:2001 specify?

SIST EN 2829:2001 specifies a test method for determining the adhesion of metallic coatings by shot peening. The scope is limited to ductile metal coatings and gives cadmium, silver and copper as examples.

The method applies to two coating conditions:

• coatings with hardness below 250 HV when the thickness is between 25 and 250 µm
• coatings with hardness at or above 250 HV when the thickness is between 10 and 60 µm

In practice, this means the first check is whether the coating falls into the thickness and hardness window covered by the standard. If it does, the document provides the reference method for an adhesion check used when the standard is called up in a specification, contract or drawing.

What are the key requirements of SIST EN 2829:2001?

SIST EN 2829:2001 centers on one practical test - shot peening - to judge how well a metallic coating stays attached to its base material. For the user, that means the document is not a general coating guide; it is a test method to be applied to defined coatings.

• Use shot peening as the adhesion test. The coating is assessed by exposing it to shot peening rather than by a visual check alone. In practice, the reader needs the correct test setup and a clear decision on whether the coating remains acceptable after the treatment.
• Limit use to ductile metal coatings. The scope names metallic coatings such as cadmium, silver and copper. This matters because the method is intended for coatings that can deform in the test without behaving like brittle layers.
• Check hardness before applying the thickness range. The standard separates coatings below 250 HV from coatings at or above 250 HV. In practice, the coating’s hardness controls which thickness window the method covers.
• Check coating thickness before testing. The applicable thickness band is different for softer and harder coatings. That matters because a coating outside the stated thickness range should not be treated as covered by this method.
• Use the standard whenever it is referenced. The scope says the method shall be applicable whenever referenced. In practice, this makes the document a specification test for procurement, inspection and acceptance, not an optional laboratory exercise.
• Treat the method as part of aerospace coating control. The standard belongs to the aerospace series and to coatings and related processes used in the aerospace industry. That tells users to apply it in controlled aerospace manufacturing and maintenance contexts.

What terms does SIST EN 2829:2001 define?

• Adhesion - the ability of a coating to remain attached to the substrate during and after the shot peening test.
• Shot peening - the impact-based process used here as the test action to challenge the coating bond.
• Ductile metal coatings - metallic coatings that can deform under the test conditions; these are the coatings covered by the standard.
• Coating thickness - the layer thickness used to determine whether the method applies to a particular coating.
• Hardness - the coating property that sets the scope limits in the document’s applicability ranges.
• Aerospace series - the family of standards intended for aerospace products and processes.

Who uses SIST EN 2829:2001?

SIST EN 2829:2001 is used by aerospace manufacturers, coating suppliers, test laboratories, quality managers, inspectors and buyers. They use it to specify an adhesion test, verify a coating before acceptance, and align supplier and customer expectations for coated parts.

It is especially relevant where metallic coatings on aerospace components must be checked as part of incoming inspection, process qualification, or contract review. In practice, it helps teams speak the same technical language when a drawing or procurement specification calls for the shot peening adhesion test.

What changed in SIST EN 2829:2001 from the previous edition?

SIST EN 2829:2001 is identified as identical to EN 2829:1994.

Which standards are used with SIST EN 2829:2001?

The only companion reference identified in the publication is EN 2829:1994, which is the European standard corresponding to this Slovenian text. Users working across national and European documentation can cross-check that reference when they need the same test method in another publication format.

What does the SIST EN 2829:2001 document contain?

The document contains the multilingual title pages, the scope statement, the ICS 49.040 classification for coatings and related processes used in the aerospace industry, and the note identifying the Slovenian standard as identical to EN 2829:1994. Its technical content is a single adhesion test method based on shot peening for metallic coatings.

For practical use, that means the standard serves as a short reference for specifying, testing and accepting coated aerospace parts. It gives readers the method name, the intended coating types, and the applicability limits needed before the test is called up.
