SIST EN ISO 9163:2005 PDF

Overview

EN ISO 9163:2005 (ISO 9163:2005) specifies standardized laboratory methods for producing test specimens from textile glass rovings and for determining the tensile stress at break of impregnated rovings. The standard defines a detailed reference method (moulded epoxy end tabs) and a short method (no tabs or simple cardboard/composite tabs). It is intended for both assembled (multistrand) and direct (multifilament) rovings; the short method is described specifically for 1 200 tex rovings because this linear density spreads most easily into a flat tape during impregnation.

Key topics and technical requirements

• Two test routes
  • Reference method: test specimens with moulded epoxy tabs - suitable for a range of linear densities.
  • Short method: quicker specimen preparation, described for 1 200 tex only.
• Specimen production
  • Impregnation equipment: reel with tension control (capable of ~0.2 N–20 N), impregnation vat (up to 130 °C ±5 °C recommended), and a stainless-steel die to produce a defined circular cross-section.
  • Typical die diameters (examples): ~0.8 mm (800 tex), 1.1 mm (1 200 tex), 1.15 mm (1 600 tex), 1.4 mm (2 400 tex), 2.0 mm (4 800 tex).
  • Resin requirements: viscosity < 0.4 Pa·s at impregnation temperature, pot life > twice winding time, and min. elongation at break ≈ 5%.
  • Void content of impregnated roving should be
