SIST EN 2558:2001 is a Slovenian national standard published by SIST and stated to be identical to EN 2558:1997. It specifies a method for determining the volatile content in carbon fibre preimpregnates used for aerospace applications. In practice, it gives laboratories and material suppliers a common way to check a key material characteristic before use in aerospace manufacture.

What does SIST EN 2558:2001 specify?

SIST EN 2558:2001 covers one test method for measuring the volatile content of carbon fibre preimpregnates. The scope is focused on aerospace applications, so the document is aimed at material control for that sector rather than general-purpose composites work.

For readers, that means the standard is relevant when volatile content is a quality characteristic that must be checked, compared, or reported consistently. It is the kind of document used when a buyer, supplier, or test lab needs the same basis for judging whether a prepreg batch is suitable for further processing.

What are the key points of SIST EN 2558:2001?

SIST EN 2558:2001 is centered on a single measurement task: determining volatile content in carbon fibre preimpregnates. That matters because volatile content is a material property that can affect handling, storage condition, and downstream processing decisions.

• Material covered: carbon fibre preimpregnates. This keeps the method tied to prepreg materials, not to cured parts or other fibre systems.
• Application area: aerospace. The standard is intended for materials used in aerospace supply chains, where consistent material data are important.
• Property measured: volatile content. Users apply the method when they need to know how much volatile material is present in the prepreg.
• Purpose of the method: provide a repeatable way to measure that property. In practice, this supports comparison between lots, suppliers, or test results from different laboratories.
• Use in quality control: the standard is relevant for incoming inspection, batch release, and supplier qualification. Those are the situations where a defined test method helps avoid arguments over how the result was obtained.
• Common technical language: the document uses the aerospace-series term “preimpregnates” and the property name “volatile content.” That helps ensure everyone is speaking about the same material characteristic.

Who uses SIST EN 2558:2001?

SIST EN 2558:2001 is used by test laboratories, aerospace material engineers, quality managers, and suppliers of carbon fibre preimpregnates. Buyers and inspectors may also use it when they need a contractually defined method for checking a material property.

For these users, the standard supports routine testing and acceptance decisions. A lab uses it to generate comparable results, a supplier uses it to characterize product lots, and a buyer or quality team uses it to specify what test basis should be applied.

What does the SIST EN 2558:2001 document contain?

The document identifies the standard in Slovenian, English, German, and French, and states its equivalence to EN 2558:1997. It also places the standard in ICS category 49.025.40, under rubber and plastics.

From the technical point of view, the document is a method standard for one measured property: volatile content in carbon fibre preimpregnates. That makes it a reference for laboratory testing and material control, rather than a design standard or a product specification.
