BS EN 50342-7 is a part of an international multi-series standard that focuses on lead-acid starter motorcycle batteries.
BS EN 50342-7 is applicable to lead-acid batteries used primarily as a power source for the starting of internal combustion engines, lighting, and ignition of motorcycles, power sport vehicles, and all-terrain vehicles up to a maximum capacity of 35 Ah (C10) (further on referred as batteries). The nominal voltage is 12 V or 6 V.
Test definitions and criteria in BS EN 50342-7 are written for batteries with a nominal voltage of 12 V only. For batteries with a nominal voltage of 6 V, all voltages have to be divided by two.
BS EN 50342-7 stipulates the technical specifications such as related terms and definitions, general requirements, general test conditions, test sequences, inspections, and test procedures for lead-acid starter batteries.
BS EN 50342-7 on Lead-acid starter batteries is useful for:
The tap density of ceramic powders is nothing, but increased bulk density achieved after tapping a repository containing the powder sample, mechanically. The tap density can be acquired by mechanically tapping a graduated measuring cylinder or container carrying the powder sample.
ISO 23145-1 lays down the technicalities for carrying out a test procedure to determine the tap density of the ceramic powders. It gives you detailed information about the apparatus needed to perform the test, explains the principle of the test, helps the users to execute the calculations as well as concludes the final test report.
The test procedure given in ISO 23145-1, helps the users to acknowledge the packing properties of the ceramic powder, which can influence the operations critical to solid dosage manufacturing, including bulk storage, powder flow, and compaction.
