That means one range pair is composed by a positive load increase which surpasses a predetermined value and the next negative load decrease of the same magnitude. By the procedure all double ranges of closed hysteresis loops are counted as in the Rainflow method but neglecting their mean value.

The significant advantage of this counting method is that it is one-parametric and can easily be put in a graphical form in a so called spectrum. The disadvantage is that the upper and lower stresses of the load-time history are often not given in the right quantity and the spectrum is then too weak. A comparison with the result of the evaluation method \u201cLevel Crossing\u201d is therefore recommended.<\/p>\n\n\n\n<div class=\"wp-block-file\"><a href=\"https:\/\/swift-online.de\/en\/wp-content\/uploads\/sites\/2\/2019\/08\/SWIFT-Meth_RP_en.pdf\">Range Pairs Datasheet<\/a><a href=\"https:\/\/swift-online.de\/en\/wp-content\/uploads\/sites\/2\/2019\/08\/SWIFT-Meth_RP_en.pdf\" class=\"wp-block-file__button\" download>Download<\/a><\/div>\n","protected":false},"excerpt":{"rendered":"<p>With this evaluation method the ranges are counted in pairs.
