Gilson Screen Tray Reverification Services assure that Screen Trays for Gilson Testing Screen, Test-Master®, and Porta-Screen® units remain in compliance with ISO 565/3310-1 requirements. Previously purchased Screen Trays are shipped to Gilson’s Verification Laboratory where they undergo a process identical to the Verification of New Screen Trays. A NIST traceable optical comparator individually measures a specified number of openings in each tray. A statistical analysis is performed using a computerized system, providing documentation that the Screen Trays meet Inspection or Calibration specifications.

ISO 565/3310-1 Inspection Screen Tray Reverification confirms that in-service screens remain compliant with ISO Inspection Grade requirements and have 99% statistical confidence that the standard deviation of opening sizes is accurate. Documentation includes measurements and statistical analysis. When documentation of accuracy and repeatability is important, Inspection Grade wire cloth is a good choice.
ISO 565/3310-1 Calibration Screen Tray Reverification documents that Screen Trays currently in use meet ISO Inspection Grade requirements. Documentation will show measurements and a statistical level of confidence of 99.73% that the standard deviation of openings is within the allowable maximum. Calibration Grade wire cloth is best for applications where the highest degree of accuracy is required.
