SIST EN 12971-1:2000

SIST EN 12971-1:2000 is a Slovenian standard from SIST for textile glass chopped strands. It specifies a designation method for chopped strands made from continuous filament textile glass strands, so manufacturers and specifiers can use a common basis for product specifications. The designation system is intended for chopped strands used to reinforce plastics and to make synthetic bonded non-woven materials.

What does SIST EN 12971-1:2000 specify?

SIST EN 12971-1:2000 is Part 1 of EN 12971, and its subject is designation. The standard sets out how to name or identify textile glass chopped strands so they can be used consistently in specifications and purchasing documents.

The scope is narrow and practical:

• it applies to chopped strands made from continuous filament textile glass strands
• it is intended as a basis for specifications
• it covers chopped strands used for reinforcement of plastics
• it covers chopped strands used in the manufacture of synthetic bonded non-woven materials
• it excludes chopped strands made from staple fibres

In practice, that means the standard is for people who need a common designation system, not for materials outside this textile glass chopped-strand field.

What are the key requirements of SIST EN 12971-1:2000?

The main requirement in SIST EN 12971-1:2000 is to use the agreed designation method for the specified type of chopped strand. Clause 1.1 establishes the method, and Clause 1.2 limits where it can be used.

• Clause 1.1 establishes a designation method for chopped strands made from continuous filament textile glass strands. In practice, suppliers and buyers can use the same naming approach when describing the material.
• Clause 1.1 says the method may be used as the basis for specifications. In practice, this helps a purchaser build a specification around a common designation rather than inventing one internally.
• Clause 1.2 limits the system to chopped strands used for reinforcement of plastics. In practice, users in plastics reinforcement can rely on the same designation when comparing products.
• Clause 1.2 also limits the system to chopped strands used for the manufacture of synthetic bonded non-woven materials. In practice, this supports consistent identification in non-woven material production.
• Clause 1.2 excludes chopped strands made from staple fibres. In practice, staple-fibre products need a different specification route.

The document is therefore about identification and specification alignment. It helps reduce ambiguity when the material is ordered, named, or referenced in a technical file.

Who uses SIST EN 12971-1:2000?

SIST EN 12971-1:2000 is used by people who specify, supply, buy, or check textile glass chopped strands. That includes manufacturers of reinforcement materials, buyers for plastics and non-woven production, and quality staff who need a clear product designation.

It is relevant in the plastics reinforcement sector and in the manufacture of synthetic bonded non-woven materials. In practice, these users need a common language for material identification so that orders, specifications, and internal records refer to the same product type.

What does the SIST EN 12971-1:2000 document contain?

SIST EN 12971-1:2000 contains the designation system for textile glass chopped strands made from continuous filament textile glass strands. It gives the framework that can be used when writing specifications for reinforcement of plastics and for synthetic bonded non-woven materials.

The document is focused on a narrow technical function - naming and specifying the material. The Slovenian publication is identified as identical to EN 12971-1:1999, and the standard is classified under Textile glass materials.
