Specification summary of DIN 6796 as applied to conical spring washers (hv): the dimensions the standard fixes, the full size range supplied, and the related designations commonly cross-referenced.
DIN 6796 — Scope
DIN 6796 is "Conical spring washers for bolted connections".
Tolerance & Product Grades
DIN 6796 does not divide conical spring washers (hv) into product grades. Tolerances are given as limits on the individual dimensions in the table.
Where a general-tolerance class is cited on the drawing instead, it applies to the dimensions not otherwise toleranced.

Equivalent Standards
Where direct equivalents exist (ISO ↔ DIN, ISO ↔ ASME), they are listed on the parent Conical Spring Washers (HV) page.
Always confirm against the dimensions on this page, since some "equivalent" standards differ in tolerances and head geometry.
Companion Standards
DIN 6796 controls the geometry of conical spring washers (hv). Surface finish is governed by separate finish standards such as ISO 4042 for electroplating, and corrosion testing by ISO 9227 (neutral salt spray). Mechanical performance is set by the documents specific to this part family — ISO 898-1 and ISO 898-2 apply to bolts, screws, studs and nuts, and not here.
Custom manufacturing · Made to drawing
Need a washer to this standard in a non-standard size?
Parts built to DIN 6796 are already in the catalog, so a special is usually a variation on existing tooling rather than a new design — which is what keeps the cost down. Made by stamping or punching.
Minimum order from 2,000 pieces; samples within 7 days of drawing approval.
