What is BS EN 61649 - Weibull analysis about?

BS EN 61649 is a technical specification that provides methods for analysing data from a Weibull distribution using continuous parameters such as time to failure, cycles to failure, mechanical stress, etc. BS EN 61649 is applicable whenever data on strength parameters, e.g., times to failure, cycles, stress, etc. are available for a random sample of items operating under test conditions or in-service, for the purpose of estimating measures of reliability performance of the population from which these items were drawn. BS EN 61649 is applicable when the data being analysed are independent, and identically distributed. This should either be tested or assumed to be true (see IEC 60300-3-5
