The lasting adhesive to be tested iscoated onto these strips and two strips are bonded to produce test pieces of a specified form.The heat resistance of the bonds is determined by heating the test pieces to cohesion (cohesive) failure in a warmair cabinet under a specified constant load and at a temperature increasing at a rate of 2 C/min.5 SafetyPersons using this standard shall be familiar with normal laboratory practice.This standard does not purport to address all safety problems, if any, associated with its use.It is the responsibility of the user to establish safety and health practices and to ensure compliance with anyEuropean and national regulatory conditions.6 ApparatusThe items required will depend on the types of materials used:SIST EN 12964:2002

The angle between the inner and outer cutting surfaceshall be approximately 20;6.2 Hand brushFor cleaning the surface of the test material;6.3 Adhesive applicatorTo ensure a uniform and even coating of the adhesive under test using preferably the type of applicatorrecommended by the manufacturer of the adhesive.Unless otherwise specified, for lasting adhesives supplied in liquid form use a brush, a roller or a coating machine,for solid lasting adhesives use an applicator equipped with a melting chamber and an applicator nozzle with thefollowing requirements:a) The melting chamber shall heat the adhesive by an electric device to its application temperature (usuallybetween 100 C and 300 C). The temperature of the nozzle shall be kept within ± 5 C of the specifiedtemperature.b) The applicator shall allow the even distribution of the adhesive over the test piece surface. It shall include an airdriven or mechanical system which produces a controlled dose of the melted adhesive. The use of a nozzle withseveral orifices is recommended as it facilitates the distribution of the melted adhesive over the whole surface ofthe test material.c) During application, the test material shall rest on a mobile carriage/ traveller which allows the application of theadhesive along the length of the test piece at a controlled speed.6.4 Heat activatorFor heating adhesive coats to the required temperature.6.5 Equipment for measurement of temperatureThermocouple, thermoindicator papers or melting powders for measuring the temperature of activated adhesivecoats or a non-contact temperature measurement device.6.6 Pressing deviceProviding an even pressure of up to 0,6 MPa over the whole of the surface to be bonded;6.7 Warm air cabinetWith forced ventilation capable of maintaining temperatures between 25 C and 300 C wit
