The multiple “wisp” test is proposed here as a reasonable economic compromise which goes a substantial way towards producing representative sampling and a stable statistic of testing representative samples of fibers for strength and extensibility. The latter is assessed from the coefficient of variation of test results. It is especially applicable where strength, extensibility and work-to-rupture are the principal characteristics being tested.
