Glass reinforced plastics - Determination of indentation hardness by means of a Barcol hardness tester

This European Standard specifies a method for determining the indentation hardness of glass reinforced plastics materials by means of a Barcol hardness tester.
The Barcol hardness tester is a portable device which can be used with a stand. This method is suitable for testing the indentation hardness of individual test specimens or finished products for production control purposes.

Glasfaserverstärkte Kunststoffe - Bestimmung der Eindruckhärte mit einem Barcol-Härteprüfgerät

Diese Europäische Norm legt ein Verfahren zur Bestimmung der Eindruckhärte von glasfaserverstärkten Kunststoffen unter Verwendung eines Barcol-Härteprüfgeräts fest.
Das Barcol-Härteprüfgerät ist ein tragbares Gerät, das mit einem Gestell verwendet werden kann. Dieses Verfahren ist für die Prüfung der Eindruckhärte von einzelnen Probekörpern oder Fertigprodukten zur Produktionskontrolle geeignet.

Matières plastiques renforcées de verre - Détermination de la dureté par pénétration au moyen d'un appareil d'essai de dureté Barcol

La présente Norme européenne spécifie une méthode pour la détermination de la dureté par pénétration des matières plastiques renforcées de verre au moyen d’un appareil d’essai de dureté Barcol.
L’appareil d’essai de dureté Barcol est un dispositif portatif qui peut être utilisé avec un support. Cette méthode est adaptée pour la détermination de la dureté par pénétration d’éprouvettes individuelles ou de produits finis à des fins de contrôle de la production.

S steklom ojačeni polimerni materiali - Merjenje trdote z napravo po Barcolu

Ta evropski standard določa metodo za ugotavljanje trdote s steklom ojačenih polimernih materialov z napravo po Barcolu, model N° 934 1.
Ker je naprava po Barcolu prenosna, je ta metoda primerna za preskušanje trdote izdelanih delov in posameznih preskusnih vzorcev za namene kontrole proizvodnje.

Overview

EN 59:2016 - Glass reinforced plastics: Determination of indentation hardness by means of a Barcol hardness tester - is a CEN European Standard that specifies a portable, production‑control method to measure the indentation hardness of glass reinforced plastics (GRP) using a Barcol impressor. The method is suited for individual test specimens or finished products and defines apparatus, calibration, specimen preparation, test procedure and reporting requirements.

Key topics and technical requirements

• Apparatus: Use a Barcol hardness tester with a hardened steel truncated‑cone indenter and presser foot, depth measuring system and means to apply the specified test force. The device can be handheld or mounted on a stand.
• Measurement scale: Penetration 0.000–0.760 mm corresponds to 100–0 Barcol units; scale resolution = 1 Barcol unit per 0.0076 mm penetration.
• Test force and calibration: Test load values for calibration are defined across the Barcol range (e.g., 0 → 61.10 N, 100 → 71.30 N). Calibration and verification use aluminium reference plates and a glass/hardened steel check plate. Maximum cumulative deviation allowed from reference is ±3 Barcol units (±1 from device, ±2 from reference plate).
• Specimen requirements: Minimum specimen thickness 1.5 mm; test area must be smooth, undamaged and at least 3 mm from edges or prior impressions.
• Conditioning and atmosphere: Follow EN ISO 291 standard atmospheres (e.g., 23 ± 2 °C / 50 ± 2 % RH with 16 h conditioning when applicable).
• Procedure: Place specimen on a stable hard surface, ensure indenter is perpendicular, apply a large quick manual force (~80 N) and record the highest instantaneous reading (within 1 s after movement exceeds 5 Barcol units). Account for creep-prone materials by capturing the peak reading.
• Statistical control: Take enough measurements so the mean has a standard deviation of ±4 % at 95 % probability.
• Reporting: Report EN 59 reference, material ID, specimen details, conditioning, number of measurements, mean hardness (rounded to nearest integer) and test date.

Applications and users

• Quality control and production monitoring of glass reinforced plastics (GRP) parts and laminates.
• Incoming inspection for composite components in marine, transport, construction and tooling industries.
• R&D and materials testing labs evaluating matrix/reinforcement local hardness and surface cure.
• Certification bodies and compliance testing where a portable, repeatable hardness check is required.

Related standards

• EN ISO 291 - Plastics: standard atmospheres for conditioning and testing (referenced by EN 59).
