1.1 This standard prescribes methods for cleaning of the cooling system of internal combustion engines free from scales and subsequently inhibiting the coolant with suitable materials for protection against corrosion and prevention of scale formation.
1.2 This standard also lays down the qualitative requirements of a descaling agent and a corrosion-cum-scale preventor. A procedure for descaling the radiator system is also given in 2.3.
