Rubber- or plastics-coated fabrics - Physical and mechanical tests - Determination of flex resistance by the flexometer method (ISO 32100:2018)

This document specifies a test method for determining the flex resistance of rubber- or plastics‑coated fabrics in the folded condition. The test method is applicable only to products which can be clamped in the test apparatus used and to products with which the fold made in the test specimen can be caused to move back and forth along the specimen during the test.
The appearance of the test specimen, after completion of either the flex number (see 3.1) or a specified number of flex cycles, is taken as a measure of the flex resistance in the folded condition.

Mit Kautschuk oder Kunststoff beschichtete Textilien - Physikalische und mechanische Prüfungen - Bestimmung der Dauerbiegefestigkeit nach dem Flexometer-Verfahren (ISO 32100:2018)

Dieses Dokument legt ein Prüfverfahren zur Bestimmung der Dauerbiegefestigkeit von mit Kautschuk oder Kunst¬stoff beschichteten Textilien in gefaltetem Zustand fest. Das Verfahren ist nur für solche Erzeugnisse geeignet, die ohne Zwang in das Prüfgerät eingespannt werden können und für Erzeugnisse, bei denen die Falte des Probekörpers während des Versuchs auf- und abläuft.
Das Aussehen der Probekörper nach Beendigung entweder der Faltzahl (siehe 3.1) oder der vereinbarten Anzahl von Faltbeanspruchungen gilt als Maß für die Dauerbiegefestigkeit in gefaltetem Zustand.

Supports textiles revêtus de caoutchouc ou de plastique - Essais physiques et mécaniques - Détermination de la résistance à la flexion à l'aide d'un flexomètre (ISO 32100:2018)

Le présent document spécifie une méthode d'essai permettant de déterminer la résistance à la flexion des supports textiles revêtus de caoutchouc ou de plastique, à l'état plié. La méthode d'essai s'applique uniquement aux produits qui peuvent être fixés dans l'appareillage d'essai utilisé et aux produits avec lesquels le pli formé sur l'éprouvette peut être entraîné dans un déplacement d'avant en arrière le long de l'éprouvette pendant l'essai.
L'aspect de l'éprouvette, après avoir effectué soit le nombre de flexions (voir 3.1) soit un nombre spécifié de cycles de flexion, est considéré comme la mesure de la résistance à la flexion, à l'état plié.

Ta dokument določa preskusno metodo za ugotavljanje odpornosti proti upogibanju upognjenih gumiranih ali plastificiranih tekstilij. Preskusna metoda se uporablja samo za izdelke, ki jih je mogoče vpeti v uporabljeno preskusno napravo, in za izdelke, pri katerih se lahko pregib na preskušancu med preskusom premika naprej in nazaj.
Videz preskušanca se po zaključku števila upogibov (glej 3.1) ali določenega števila upogibnih ciklov upošteva kot merilo odpornosti proti upogibanju v upognjenem stanju.

Overview

EN ISO 32100:2018 - Rubber- or plastics-coated fabrics: Determination of flex resistance by the flexometer method is a CEN-endorsed international standard that specifies a laboratory test to assess the flex resistance of rubber- or plastics-coated textiles in the folded condition. The method measures how repeated folding (flex cycles) affects the appearance of a coated fabric specimen; the visual condition after a defined flex number or after a specified number of cycles is used as the performance indicator.

This standard applies only to products that can be clamped in the test apparatus and where the fold can be made to run back and forth along the specimen during testing. EN ISO 32100:2018 updates the 2010 edition and is intended for use in quality control, product development and conformity assessment.

Key topics and technical requirements

• Test principle: One end of a folded test piece is clamped in a movable upper clamp and the other end in a fixed lower clamp; the upper clamp reciprocates so the fold travels along the specimen and produces flex cycles.
• Apparatus: Flexometer with upper (movable) and lower (fixed) clamps, counter, magnifier (×6), and mandrel (10 mm diameter). The upper clamp reciprocates about a horizontal axle with a nominal flex angle of 22.5° and typical frequency around 100 cycles/min (as specified).
• Specimens: Typical specimen size 70 mm × 45 mm; special shapes allowed in certain cases. At least three specimens cut longitudinal to manufacture direction and three perpendicular.
• Conditioning and atmosphere: Tests are carried out in standard atmosphere B (ISO 2231 - 23 °C, 50 % r.h.) with specified conditioning time.
• Procedure and assessment: Periodic visual examination (with magnifier) after the agreed flex number or after specified cycles. The appearance (cracking, delamination, etc.) is recorded as the measure of flex resistance.
• Reporting: Test parameters, specimen orientation, condition, flex number/cycles and observed damage are required in the test report.

Applications

• Routine quality control for rubber- or plastics-coated fabrics used in tarpaulins, protective clothing, inflatable products, automotive interiors, conveyor belts and technical membranes.
• Comparative testing during product development to evaluate coatings, formulations and construction.
• Supplier qualification and specification compliance checks for coated textiles where resistance to repetitive folding is critical.

Who uses this standard

• Textile and coating manufacturers
• Independent testing laboratories and certification bodies
• Product designers and R&D teams
• Purchasing/specification writers and quality assurance professionals
