Overview
ISO 10630:1994 - "Industrial plate screens - Specifications and test methods" defines technical requirements and test procedures for perforated metal plate used in industrial screening. The standard applies to perforated plates made of low-carbon steel (as referenced to ISO 7805‑1 and ISO 7805‑2), supplied flat or in coils, with nominal hole sizes from 1 mm (round) and 4 mm (square) up to 125 mm (per ISO 2194) and a maximum plate thickness of 12.5 mm. ISO 10630 provides definitions, dimensional tolerances, inspection methods and acceptance criteria to ensure consistent screening performance and interchangeability.
Key topics and requirements
- Scope & definitions: clear terms for plate, sheet, coil, perforated plate, pitch, bridge width (bar), margins, and percentage open area.
- Material and sizes: low-carbon steel plates, hole size ranges, and maximum thickness (12.5 mm).
- Dimensional tolerances: requirements for hole size, pitch and plate dimensions - hole and pitch measurement procedures refer to ISO 7805‑1/2 depending on thickness.
- Geometric controls: squareness (amount out‑of‑square), plate width/length, margin widths and acceptable deviations.
- Flatness and edge geometry: measurement methods on a reference surface, roller-levelling considerations, and limits for edge bow and wavy edges (to be agreed when outside standard limits).
- Surface defects and irregularities: rules and test methods for breakaway zones, burr heights and shearing burrs. (Example: maximum permissible burr heights are specified by plate thickness in the standard.)
- Coiled plate provisions: special conditions for coils (limited to thickness
