SIST EN 12654-1:2000

SIST EN 12654-1:2000 is a Slovenski inštitut za standardizacijo standard for textile glass yarns. It specifies the designation system for yarns based on continuous filament textile glass, so manufacturers, buyers, and quality teams can identify and order these yarns in a consistent way. The standard applies to single yarns and folded yarns, and it draws a clear boundary around other yarn types.

What does SIST EN 12654-1:2000 specify?

SIST EN 12654-1:2000 specifies how to designate textile glass yarns made from continuous filament textile glass. In practice, it is a naming and identification standard: it helps everyone in the supply chain use the same product description for the same kind of yarn.

The scope is limited to single yarns and folded yarns. It excludes textured yarns, yarns based on staple fibre, rovings, and pre-impregnated yarns, so the designation system should not be used for those products.

The document is focused on designation rather than performance testing. For users, that means it is most useful when writing product specifications, purchase descriptions, catalog entries, or internal material codes.

What are the key requirements of SIST EN 12654-1:2000?

The main requirement is to use the standard designation system for the covered yarn family. That matters because textile glass products are often traded and documented by name, and the designation needs to identify the yarn type clearly.

• Apply the system only to continuous filament textile glass yarns.
  This keeps the designation consistent with the material class the standard was written for.

• Use it for single yarns.
  A single yarn is treated as a distinct product type, which helps avoid confusion when ordering or checking incoming material.

• Use it for folded yarns.
  Folded yarns are included alongside single yarns, so the designation must show that the product is a folded construction when that matters for processing or buying.

• Do not use it for textured yarns.
  Textured yarns are outside the scope, so a buyer or specifier needs another reference for those products.

• Do not use it for yarns based on staple fibre.
  This prevents mixed terminology between continuous-filament yarns and yarns made from staple fibres.

• Do not use it for rovings.
  Rovings are another textile glass product form and need separate identification, especially in procurement and production records.

• Do not use it for pre-impregnated yarns.
  Pre-impregnated products have different handling and specification needs, so they are excluded from this designation system.

• Treat the standard as a communication tool for specification.
  In practical terms, it is meant to support clear product naming in datasheets, orders, and quality documentation.

What terms does SIST EN 12654-1:2000 define?

• Textile glass - Glass material intended for textile use, which is the material family covered by the standard.
• Continuous filament textile glass - Textile glass supplied as continuous filaments, which is the base material for the yarns in scope.
• Single yarns - Yarn in a single strand form, included in the designation system.
• Folded yarns - Yarn made by combining strands, also included in the designation system.
• Textured yarns - A yarn form specifically excluded from this standard’s scope.
• Rovings - Another glass-fibre product form that is excluded from this designation system.
• Pre-impregnated yarns - Yarn products that already contain impregnation material and are excluded from the scope.

Who uses SIST EN 12654-1:2000?

SIST EN 12654-1:2000 is used by textile glass manufacturers, converters, distributors, buyers, and quality personnel. They use it when describing yarns in specifications, comparing offers, labelling stock, and checking that the product name matches the intended yarn type.

It is also useful for engineering and procurement teams that need to distinguish between single yarns and folded yarns. That distinction matters in weaving, processing, handling, and cost control.

What changed in SIST EN 12654-1:2000 from the previous edition?

SIST EN 12654-1:2000 is identical to EN 12654-1:1998.

What does the SIST EN 12654-1:2000 document contain?

SIST EN 12654-1:2000 is a designation standard for textile glass yarns, not a test method or product-performance standard. Its practical content is the system for naming the yarns that fall within scope, so users can describe them consistently in technical and commercial documents.

The front matter identifies it as part of the textile glass materials field, classified under ICS 59.100.10. It also shows that the Slovenian standard mirrors EN 12654-1:1998, which helps users connect the national publication with the European standard family.
