The meter readings are plotted automatically against the respective volumes of titrant and the endpoint is taken when the volume corresponds to a pH of 11

Test method for resistance to fire of cables required to maintain circuit integrity under fire conditions Ingestion-build-64721 an estimate of average relative1 Scope This British Standard gives a test method for resistance to fire of cables required to maintain circuit integrity under fire conditions. It is applicable to cables of rated voltage not exceeding 600 1 000 V and of overall diameter less than or equal to 20 mm. The test given in this British Standard is applicable to cables having two or more insulated conductors, whether or not the cables incorporate other metallic elements such as armour,
