SIST EN 1514-6:2004

SIST EN 1514-6:2004 is the Slovenian adoption of EN 1514-6:2003. It specifies the construction, dimensions and marking of covered serrated metal gaskets for use with steel flanges to EN 1092-1. The standard is for PN-designated flanges from PN 10 to PN 100, with sizes up to and including DN 3000.

What does SIST EN 1514-6:2004 specify?

SIST EN 1514-6:2004 covers covered serrated metal gaskets intended for flanges complying with EN 1092-1. In practice, it tells designers, buyers and gasket suppliers which gasket family is covered, which flange series it fits, and the size and pressure-designation range it addresses.

The document also sets out what it does not cover. It does not extend to covered serrated metal based heat exchanger gaskets with pass bars or to large vessel gaskets, although it notes that the same principles can be applied where no dedicated document exists.

The standard is organized around the specification itself, with Annex A giving purchaser information for cases where the supplier chooses the gasket material.

What are the key requirements of SIST EN 1514-6:2004?

The main requirement is that the gasket type, dimensions and marking are defined for covered serrated metal gaskets used with EN 1092-1 steel flanges. That matters because the gasket has to match the flange joint geometry and be identified correctly in ordering and inspection.

The scope is tied to specific PN ratings - PN 10, PN 16, PN 25, PN 40, PN 63 and PN 100. For users, this means the standard is only meant to be used when the flange pressure designation matches one of those ratings.

The size range extends up to and including DN 3000. In practice, that gives purchasers and manufacturers a clear upper size limit when selecting or producing gaskets for large flange joints.

The document separates the covered serrated metal gasket from other gasket families. Heat exchanger gaskets with pass bars and large vessel gaskets are outside the main scope, so buyers should not assume this standard is the right reference for those designs.

The standard also points users to material-selection information in Annex A when the supplier is expected to choose the gasket material. That is important for purchasing, because service conditions still have to be communicated clearly even when the exact material is not fixed by the buyer.

The note in the scope links this part to the rest of the EN 1514 series. If a project uses a different flange standard or a different gasket type, another part of the series may be the right document instead.

What terms does SIST EN 1514-6:2004 use?

• Covered serrated metal gasket - the gasket type covered by this part, intended for use with steel flanges.
• PN - the pressure designation used for the flange ratings in this standard, such as PN 10 and PN 100.
• DN - the nominal diameter used to express the flange size range, here up to DN 3000.
• EN 1092-1 - the flange standard with which these gaskets are intended to be used.
• Steel flanges - the flange material context named in the title and scope for this gasket family.
• Pass bars - a feature of a heat exchanger gasket type that is outside the main scope.
• Large vessel gaskets - another gasket family named as outside the main scope.

Who uses SIST EN 1514-6:2004?

SIST EN 1514-6:2004 is used by gasket manufacturers, flange and joint designers, purchasers, and quality or inspection staff who need a common reference for gasket dimensions and marking. It is also relevant to engineers specifying piping joints and to buyers checking that a quoted gasket matches the required flange designation and size.

For suppliers, the standard helps with product definition and marking. For buyers, it helps compare offers and give the right material and service information when Annex A applies.

What changed in SIST EN 1514-6:2004 from the previous edition?

SIST EN 1514-6:2004 is identical to EN 1514-6:2003.

Which standards are used with SIST EN 1514-6:2004?

The document refers users to several related flange and gasket standards:

• EN 1092-1 - the flange standard for which this gasket part is written.
• EN 1514-1, EN 1514-2, EN 1514-3, EN 1514-4 - other EN 1514 parts that give dimensions for other gasket types.
• prEN 1514-7 and prEN 1514-8 - additional EN 1514 parts named for other gasket types.
• EN 1092-2, prEN 1092-3 and EN 1092-4 - flange standards mentioned in the note as contexts for the other gasket parts.

What does the SIST EN 1514-6:2004 document contain?

SIST EN 1514-6:2004 contains the specification for covered serrated metal gaskets, including the construction, dimensions and marking rules needed for use with EN 1092-1 steel flanges. It also contains the scope note that separates this gasket family from heat exchanger gaskets with pass bars and large vessel gaskets.

Annex A adds ordering guidance for cases where the purchaser leaves gasket material selection to the supplier. That makes the document useful not only for design and manufacture, but also for procurement and service-specific specification.
