SIST EN 647:1997

SIST EN 647:1997 is the Slovenian adoption of EN 647:1993 from SIST. It specifies how to prepare a hot water extract from paper and board intended to come into contact with foodstuffs, so laboratories and quality teams can investigate certain extractives using the same preparation step.

What does SIST EN 647:1997 specify?

SIST EN 647:1997 describes the preparation of a hot water extract for investigations of certain extractives in paper and board intended to come into contact with foodstuffs. In practice, that means the standard is used when a sample has to be prepared in a defined way before chemical or migration-related investigation.

The standard is focused on one laboratory preparation step. It is relevant when a consistent extract is needed for comparison between samples, suppliers, or test reports.

What changed in SIST EN 647:1997 from the previous edition?

SIST EN 647:1997 is stated to be identical to EN 647:1993. The standard is therefore the Slovenian standardization adoption of that European standard.

Who uses SIST EN 647:1997?

SIST EN 647:1997 is used by laboratories that test paper and board for food-contact applications. They use it to prepare the hot water extract that serves as the test specimen or starting material for later investigation.

It is also relevant to manufacturers and converters of paper, board and paperboard for food packaging, and to quality, regulatory, and procurement staff who need a clear, shared reference for how samples are prepared before extractives are examined. That matters when specifications, supplier declarations, or test plans need to refer to the same preparation method.

What does the SIST EN 647:1997 document contain?

SIST EN 647:1997 is a short method standard centered on preparing a hot water extract from food-contact paper and board. The front matter identifies the topic in Slovene, English, German, and French, and classifies it under materials and articles in contact with foodstuffs and under paper, board and paperboard.

For a reader, the important point is that the document is about sample preparation for later investigation, not about the final analytical result itself. It provides the reference preparation step that allows different laboratories to work from comparable extracts.

The document also shows its relationship to the European standard EN 647:1993, which helps users trace the same method across national and European contexts. That is useful when matching internal procedures, customer requirements, or test reports to the correct standard reference.

Why this standard matters in practice

For food-contact materials, extract preparation is part of getting repeatable results. If the extract is prepared differently, later findings can be hard to compare. A standard like SIST EN 647:1997 gives a common basis for that first laboratory step.

For buyers and suppliers, the standard is a practical reference when a contract or specification calls for a hot water extract test on paper and board. It helps both sides point to the same preparation method instead of using in-house wording that may differ from one organization to another.
