ISO 15977 is the international standard for blind (pop) rivets. This page sets out what the standard governs, the size range it specifies, and the related standards you will see referenced in datasheets.
ISO 15977 — Scope
ISO 15977 specifies the dimensions and tolerances of blind (pop) rivets. Material, property class, surface finish and packaging are governed by separate documents in the same standards family (for example ISO 898-1 for the mechanical property classes of bolts and screws).
Tolerance & Product Grades
ISO 15977, alongside the related ISO 15977 / DIN 7337 entries on this site, specifies product grades (typically A or B for fine work and C for general engineering) and tolerance classes for the controlling dimensions. Choose the grade against the precision your application requires.

Companion Standards
ISO 15977 controls only the geometry of blind (pop) rivets. The mechanical strength is set by ISO 898-1 (bolts and screws) or ISO 898-2 (nuts); the surface finish is governed by separate finish standards (e.g. ISO 4042 for electroplating). For corrosion testing, the relevant document is ISO 9227 (neutral salt spray).
When to Specify ISO 15977
Choose ISO 15977 for international engineering work and OEM supply where ISO standards are the contractual reference. It is the default modern specification for blind (pop) rivets.
