(Main)Adhesives - Peel test for a flexible-bonded-to-rigid test specimen assembly - Part 1: 90º peel
Adhesives - Peel test for a flexible-bonded-to-rigid test specimen assembly - Part 1: 90º peel
This part of EN 28510 specifies a 90° peel test for the determination, under specified conditions, of the peel resistance of a bonded assembly of two adherends where at least one adherend is flexible. If a normal tensile testing machine is used for the test, the peel angle will not be constant at exactly 90º. If a constant angle of exactly 90° is required, a roller peeling device is used (see 4.1). The 90º peel test is particularly suitable for use with less flexible adherends for which a 180° peel test is not suitable because the adherends crack, break or delaminate. A 180º peel test is described in EN ISO 8510-2.
Klebstoffe - Schälprüfung für flexibel/starr geklebte Proben - Teil 1: 90° Schälversuch
Dieser Teil der EN 28510 legt eine 90°-Schälprüfung unter festgelegten Bedingungen zur Bestimmung des Schälwiderstandes von Klebungen aus zwei Fügeteilen fest, von denen mindestens eines flexibel ist. Bei Verwendung einer gewöhnlichen Zugprüfmaschine für die Prüfung liegt der Schälwinkel nicht konstant genau bei 90°. Falls ein konstanter Schälwinkel von genau 90° erforderlich ist, ist eine Walzen-Schälvorrichtung zu verwenden (siehe 4.1).
Die 90°-Schälprüfung ist insbesondere für wenig flexible Fügeteile geeignet, für welche die 180°-Schälprüfung ungeeignet ist, weil die Fügeteile hierbei Rissbildung zeigen, brechen oder delaminieren.
Eine 180°-Schälprüfung ist in der EN ISO 8510 2 beschrieben.
Adhésifs - Essai de pelage pour un assemblage collé flexible-sur-rigide - Partie 1: Pelage à 90º
La présente partie de l'EN 28510 prescrit un essai de pelage à 90° pour la détermination, dans des conditions spécifiées, de la résistance au pelage d'un assemblage collé constitué de deux supports dont au moins l'un d'entre eux est flexible. Si une machine d'essai de traction normale est utilisée pour l'essai, l'angle de pelage ne sera pas constant à exactement 90°. Il est indispensable d'utiliser un dispositif de pelage à galets (voir 4.1) si un angle constant à exactement 90° est nécessaire.
L'essai de pelage à 90° convient particulièrement bien dans le cas des supports peu flexibles pour lesquels un essai de pelage à 180° n'est pas praticable car les supports se fissurent, se cassent ou se délaminent.
Un essai de pelage à 180º est décrit dans l'EN ISO 8510-2.
Lepila - Lupilni preskus spoja prožnega in togega lepljenca - 1. del: Luščenje pod kotom 90°
Ta del standarda EN 28510 določa lupilni preskus za luščenje pod kotom 90° za ugotavljanje odpornosti proti razslojevanju lepljenca, pri določenih pogojih, iz dveh plasti, kjer je vsaj ena plast prožna. Če je za preskus uporabljena običajna naprava za natezni preskus, kot luščenja ne bo konstanten pri natančno 90°. Če je potreben konstanten kot natančno 90°, se uporabi valjčna naprava za lupljenje (glejte 4.1). Lupilni preskus za luščenje pod kotom 90° je zlasti primeren za uporabo z manj prožnimi lepljenci, za katere ni primeren preskus luščenja pod kotom 180°, ker razpokajo, se zlomijo ali oluščijo. Preskus luščenja pod kotom 180° je opisan v standardu EN ISO 8510-2.

EN 28510-1:2014 (E) 3 1 Scope This part of EN 28510 specifies a 90° peel test for the determination, under specified conditions, of the peel resistance of a bonded assembly of two adherends where at least one adherend is flexible. If a normal tensile testing machine is used for the test, the peel angle will not be constant at exactly 90º. If a constant angle of exactly 90° is required, a roller peeling device is used (see 4.1). The 90º peel test is particularly suitable for use with less flexible adherends for which a 180° peel test is not suitable because the adherends crack, break or delaminate. A 180º peel test is described in EN ISO 8510-2. 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 13887, Structural Adhesives - Guidelines for surface preparation of metals and plastics prior to adhesive bonding EN ISO 291, Plastics - Standard atmospheres for conditioning and testing (ISO 291) ISO 5725-2, Accuracy (trueness and precision) of measurement methods and results — Part 2: Basic method for the determination of repeatability and reproducibility of a standard measurement method 3 Principle A bonded assembly of two adherends is prepared using the adhesive under test. The adherends are then pulled apart at a substantially steady rate, starting at the open end of the bond, in such a way that separation occurs progressively along the length of the bonded adherends. The force is applied approximately normal to the plane of the bond, through the separated part of the flexible adherend. 4 Apparatus 4.1 Tensile testing machine (incorporating a roller peeling device if a constant peel angle of exactly 90º is required), capable of supplying a tensile force with a constant rate of grip separation. The machine shall be equipped with a force-measuring system complete with an indicator and/or a recorder. The indicated force shall not differ from the true applied force by more than 2 %. The response time of the machine shall be short enough not to affect the accuracy with which the force applied at the time of rupture can be measured. The force at rupture of the specimen shall lie in the range between 10 % and 80 % of the full-scale reading. 4.2 Grips, one of which shall be suitable for firmly clamping the rigid adherend (see 5.1.2), while the other shall be suitable for holding the flexible adherend (see 5.1.3) as shown in Figure 1. The latter grip shall be self-aligning, so that the force will be exerted normal to the plane of the
