Glass reinforced plastics - Measurement of hardness by means of a Barcol impressor

This European Standard specifies a method for determining the indentation hardness of glass reinforced plastics materials using a Barcol Impressor, Model N° 934 1 )
As the Barcol Impressor is portable, this method is suitable for testing the hardness of fabricated parts and individual test specimens for production control purposes.

Glasfaserverstärkte Kunststoffe - Bestimmung der Härte mit dem Barcol-Härteprüfgerät

Diese Europäische Norm legt ein Verfahren zur Bestimmung der Eindruckhärte von glasfaserverstärkten Kunststoffen unter Verwendung des Barcol-Härteprüfgeräts, Typ Nr. 934 1 ), fest.
Das Barcol-Härteprüfgerät ist ein tragbares Gerät, mit welchem die Härte von Teilen oder von einzelnen Probekörpern während der Produktion geprüft werden kann.

Matières plastiques renforcées de verre - Mesurage de la dureté au duromètre

La présente Norme européenne spécifie une méthode pour la détermination de la dureté par pénétration des matières plastiques renforcées de verre en utilisant un duromètre Barcol, modèle n° 934-1. )
Comme le duromètre Barcol est un appareil portatif, la présente méthode est adaptée pour les essais de dureté de pièces fabriquées et d’éprouvettes individuelles 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.

EN 59:2016 (E) 4 1 Scope 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. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN ISO 291, Plastics - Standard atmospheres for conditioning and testing (ISO 291) 3 Principle A specified indenter is forced into the test material under specified conditions and the depth of penetration measured. 4 Apparatus 4.1 Barcol hardness tester 4.1.1 Indenter, formed from a hardened steel truncated cone to the shape shown in Figure 1. The dimensions and their tolerances of the indenter are given in Table 1. It shall fit into a hollow spindle and be held down by a spring. 4.1.2 Presser foot, intended to be placed on the test specimen, to the shape shown in Figure 1. The dimensions and their tolerances of the presser foot are given in Table 1. SIST EN 59:2016
