GV-64 ISO 565, 3310-1 Inspection Screen Tray Verification is a service to upgrade Screen Trays from Compliance to Inspection Grade in accordance with ISO requirements. These trays have a specified number of openings measured in each tray after the cloth is mounted in the frame. There is a 99% confidence level that the standard deviation of these openings is within the maximum allowed by ISO. Inspection Sieves are a good choice in applications where accuracy and repeatability are critical. Each Inspection Grade Screen Tray consists of a Compliance Tray plus added Inspection Sieve Verification service and documentation. This service is for ISO Testing Screen & Test-Master Trays in sizes ranging from 125.0mm to 38µm in ISO 565, or ISO Porta-Screen® Trays with opening sizes that range from 50.0mm to 38µm. The Inspection Grade verification of new screen trays is selected online from the drop-down menu at the time of order or through Customer Service.
