Definitions

• WO-201 1/038524 A1 proposes a method for defining a cleaning limit on an electronic yarn cleaning system for a yarn.
• a statistical representation of the yarn is determined by means of measurements on the yarn.
• a cleaning limit is calculated and proposed for use, whereby a length-related number of inadmissible events to be expected with this cleaning limit is calculated and output.
• An operator can comment on the expected number of inadmissible events, according to which the cleaning limit is set automatically according to the opinion.
• the inventive method is preferably carried out by a computer.
• machine-readable carrier stored program code for performing the inventive method, when the computer program product on a
• Evaluation unit (3) is also for the determination of a probable cleaning limit as the boundary between a first parameter range in which almost all events are, and a second parameter range in which there are virtually no events, from the density function and for the calculation of a course of the Density function in an environment of the purest cleaning limit dependent cleaning index set up.
• the device includes an output unit connected to the evaluation unit for outputting the cleaning index.
• the device according to the invention comprises a measuring unit for detecting measured values of at least one property of the test material along the longitudinal direction of the test object.
• the device includes an evaluation unit connected to the measuring unit, which is used for determining values of a parameter of the test sample from the measured values, for providing an event field which is a quadrant or a part of a quadrant of a two-dimensional Cartesian
• a sufficiently long section of the test material 9 is measured.
• a measurement length of at least about 1 km is considered “sufficient”, but larger measurement lengths of, for example, 10 km or 100 km in length are preferred because they provide statistically more meaningful results
• Interpolation and / or extrapolation may be used to avoid excessive rashes and steps in the presumed purification curve 70, 70 '.
