BS EN 60684-3-248 is a part of an international multi-series standard that focuses on aspects of flexible insulating sleeving for electrical purposes

except by reference to ISO/IEC/IEEE 60559:2011 under conditions specified in Clause 17

The standard is extended to cover openable appliances and open fires operating with fan-assisted primary air

Carbonaceous materials for the production of aluminium. Baked anodes. Determination of the air permeability Ingestion-build-266356 Manufacturers and suppliers of welding1 Scope This International Standard describes a method for the measurement of the air permeability of baked anodes, by determining the resistance to airflow of a specimen of specified volume at room temperature, within the range of air permeability between 0,01 nPm (nanoperms) and 10 nPm. Green anodes are considered to be impermeable to gas. Therefore, this test is most applicable to baked carbon material. NOTE This method can also be used for
