Overview

EN 12971-3:1999 is a CEN standard titled Reinforcements - Specification for textile glass chopped strands - Part 3: Specific requirements. This part of the EN 12971 series provides a formal specification framework for chopped strands produced from continuous filament textile glass. It defines which product parameters must be specified and which may be specified when ordering, manufacturing or controlling chopped glass strands, but it does not prescribe absolute or nominal numerical values for those parameters.

Key Topics

• Scope of specification: Clarifies that the document applies to chopped strands derived from continuous filament textile glass and sets out the range of parameters relevant for product definition.
• Parameter definition: Identifies the parameters that manufacturers, purchasers and specifiers should record and communicate for consistency between suppliers and users.
• Optional parameters: Describes additional, application-dependent parameters that can be specified where required for specific processing methods or end‑use performance.
• No fixed values: Explicitly states that the standard does not set fixed numerical limits or nominal values - it standardizes how information is specified, not the performance limits.

Applications

• Manufacturers and suppliers use EN 12971-3 to structure product datasheets and to ensure clear, consistent technical communication about chopped glass strand products.
• Purchasing and procurement teams rely on the standard to create unambiguous purchase specifications that reduce misunderstandings and ensure suitable materials are supplied.
• Composite processors and converters (e.g., molding compound formulators, reinforcement compounders, R&D labs) use the specification to request the correct strand characteristics for their processing equipment and product requirements.
• Quality assurance and testing groups use the listed parameters as a basis for inspection criteria and supplier acceptance protocols.
• Specifiers and standards writers incorporate the standardized parameter list into project specifications and product standards to ensure interoperability and traceability.

Related Standards

• Part of the EN 12971 series of standards for textile glass reinforcements; consult other parts of the series for general terms, test methods, or complementary product specifications.
• Cited as a national adoption in various member bodies (example: SIST EN 12971-3:2000).

This standard is useful for anyone needing a clear, vendor‑neutral way to define and exchange technical information about textile glass chopped strands - improving procurement accuracy, manufacturing consistency and product traceability.
