Adhesives - Peel test for a flexible-bonded-to-rigid test specimen assembly - Part 1: 90° peel (ISO 8510-1:1990)
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 bonded assembly of two adherends is prepared using the adhesive under test. The adherends are then pulled apart at a 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. A figure shows a schematic diagram.
Klebstoffe - Schälprüfung für flexibel/starr geklebte Proben - Teil 1: 90° Schälversuch (ISO 8510-1:1990)
Dieser Teil der ISO-Norm 8510 beschreibt einen 90°-Schälversuch unter definierten Bedingungen zur Bestimmung des Schälwiderstandes von Klebungen aus zwei Fügeteilen, von denen wenigstens eine flexibel ist. Bei Verwendung einer normalen Zugprüfmaschine beträgt der Schälwinkel nicht konstant 90°. Falls ein konstanter Schälwinkel von genau 90° erforderlich ist, ist eine Walzen-Schälvorrichtung zu verwenden (s. 4.1.).
Adhésifs - Essai de pelage pour un assemblage collé flexible-sur-rigide - Partie 1: Pelage à 90° (ISO 8510-1:1990)
La présente partie de l'ISO 8510 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° est particulièrement utilisable pour les 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 180° est décrit dans l'ISO 8510-2.

IS0 8510-1:1990(E) Foreword IS0 (the International Organization for Standardization) is a worldwide federation of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 technical committees. Each member body interested in a subject for which ,a technical committee has been established has the right to be represented on that committee. International organizations, govern- mental and non-governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an lnter- national Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard IS0 8510-I was prepared by Technical Committee ISO/TC 61, Plastics. IS0 8510 consists of the following parts, under the general title Adhe- sives - Peel test for a f7exible-bonded-to-rigid test specimen assembly: - Part 1: 90 degree peel - Part 2: 180 degree peel Annex A of this part of IS0 8510 is for information only. 0 IS0 1990 All rights reserved.

-- - INTERNATIONAL STANDARD IS0 85104:1990(E) Adhesives - Peel test for a flexible-bonded-to-rigid test specimen assembly - Part 1: 90” peel 1 Scope This part of IS0 8510 specifies a 90° peel test for the determination, under specified conditions, of the peel resistance of a bonded assembly of twc 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 90”. If a constant angle of exactly 90° is required, a roller peeling device is used (see 4.1). The 90’ 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. IS0 5725:1986, Precision of test methods - Determi- nation of repeatability and reproducibility for a stan- dard test method by inter-laboratory tests. 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. A 180° peel test is described in IS0 85102. 4 Apparatus 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part of IS0 8510. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this part of IS0 8510 are encouraged to investi- gate the possibility of applying the most recent edi- tions of the standards indicated below. Members of IEC and IS0 maintain registers of currently valid In- ternational Standards. IS0 291: 1977, Plastics - Standard atmospheres for conditioning and testing. IS0 4588:1989, Adhesives - Preparation of metal surfaces for adhesive bonding. 4.1 Tensile testing machine (incorporating a roller peeling device if a constant peel angle of exactly 90” 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 ac- curacy 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 5.1.1), while the other shall be suitable for holding the flexible adherend (see 5.1.2) 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 bond, and linked 1 SIST EN 28510-1:1998

NOTE 1 The recommended thicknesses of test speci- mens are: metals 1,5 mm; plastics 1,5 mm; wood 3 mm; compounded rubbers 2 mm. Other thicknesses agreed on between the purchaser and the supplier of the adhesive may be used. 5.1 .l Rigid adherend The surface to be bonded shall have a width of 25,0 mm + 0,5 mm and a minimum length of 150 mm. - The preferred material is mild steel, and, if this ma- terial is used, it is convenient to use a mild-steel T-piece having a stem of dimensions 75 mm x 25 mm x IO mm. If a material other than mild steel is used, a piece of this other material of
