ISO 16889 beta-rated is the governing standard for pleated filter cartridges. This page sets out the scope of the document, reproduces the full specification table, and lists the ISO/ASTM/DIN cross-references cited in datasheets and purchase orders.
ISO 16889 beta-rated — Scope
ISO 16889 beta-rated specifies the designation system, dimensions and tolerances of pleated filter cartridges — mesh count or nominal opening, wire diameter and the permissible aperture deviations. Alloy chemistry, mechanical testing and delivery condition are governed by separate documents in the same standards family.
Tolerance Classes
ISO 16889 beta-rated defines tolerance limits on the average aperture and on the maximum single aperture, tightening as the aperture gets finer. For test-sieve duty the tighter ISO 3310-1 tolerances apply instead of the general cloth tolerances — specify sieve grade explicitly if the mesh will be used for particle-size analysis.

Companion Standards
ISO 16889 beta-rated controls the geometry of pleated filter cartridges. Companions frequently cited alongside it: ISO 565 / ASTM E11 (test-sieve aperture series), ISO 3310-1 (test sieves of metal wire cloth), ISO 4783 (selection of wire and aperture combinations), ISO 9044 (industrial woven wire cloth), and ISO 2941 (collapse/burst rating for finished filter elements).
When to Specify ISO 16889 beta-rated
Choose ISO 16889 beta-rated for international procurement and OEM supply where ISO documents are the contractual reference. It is the default modern specification for pleated filter cartridges.
