Describes three patterns using round (circular) and square perforations. The sizes of holes range down to 2 mm for square holes and to 0.5 mm for round holes. Five ratios of pitch to hole are specified which result in nominal open areas ranging from about 60 % to 23 %.
Abstract
Overview
ISO 7805-2:1987 establishes international guidelines for industrial plate screens with a thickness below 3 mm. Developed by the International Organization for Standardization (ISO), this standard focuses on perforated plates used in industrial sieving and screening applications, specifying three perforation patterns: round (circular) and square holes, with sizes ranging down to 2 mm (square) and 0.5 mm (round). Five pitch-to-hole ratios are provided, corresponding to nominal open areas from about 60% down to 23%. By standardizing dimensions, tolerances, and arrangements, helps manufacturers, suppliers, and users achieve consistency and quality in plate screen production and application.
