Full Description

This International Standard specifies a method for the determination of the corrosiveness to copper of liquid petroleum products and certain solvents. Volatile products, having a maximum vapour pressure of 124 kPa at 37,8 C are included.

Volatile products with a vapour pressure above 124 kPa at 37,8 C should be tested according to ISO 6251 (see caution below). Electrical insulating oils should be tested according to ISO 5662.

Some products, particularly natural gasolines, may have a significantly higher vapour pressure than is characteristic for their class, even if below 124 kPa at 37,8 C. For this reason, extreme caution should be exercised to ensure that the pressure vessel containing such material is not placed in a bath at 100 C. Such samples may develop sufficient pressure at 100 C to rupture the pressure vessel and cause damage and/or injury.
