What is BS EN 1965-2 - Corrosion properties of adhesives about?
Adhesives are used in a wide range of applications, such as transportation (automotive, rail) and architecture, among many others. BS EN 1965-2 describes a method to determine the ability of an adhesive to corrode a brass substrate under the influence of an applied voltage and high humidity. The temperature, humidity, ageing period and applied voltage are chosen to ensure the maximum differentiation between the corrosivity of different adhesives and are not intended to represent any particular service condition.
Who is BS EN 1965-2 - Corrosion properties of adhesives for?
BS EN 1965-2 on corrosion properties of adhesives is useful for:
- Adhesives manufacturers and suppliers
- The adhesives and sealants industry
- Chemical engineers
- Scientists and researchers
- Quality control personnel
- Laboratories for adhesive testing
Why should you use BS EN 1965-2 - Corrosion properties of adhesives?
The brass electrodes are held in contact with a flat sample of the cured adhesive. The assembly is placed in an environment with a relative humidity of 92 % at 42 °C and a direct current voltage of 100 V is applied across the electrodes for four days. Following this, the brass surface is examined and the extent of the tarnishing and/or corrosion is decided on the basis of discolouration.
BS EN 1965-2 provides you with detailed procedures and methods for determining and classifying corrosion to a brass substrate. BS EN 1965-2 provides you with apparatus, sampling, transport, storage, and preparation of test pieces, preparation of reagents and apparatus, pre-treatment of test pieces, and test procedure.
The specifications given in BS EN 1965-2 enable you to standardize the quality of adhesives which contributes a lot to maintaining the high quality and efficient functioning.
