This document describes a method of determining the hole expansion ratio in metallic sheets and strips with a thickness range of 1,2 mm to 6,0 mm inclusive and a width of at least 90 mm. NOTE This test is normally applicable to sheet metal and is used to assess the suitability of the product for forming flanges.
Abstract
Overview
ISO 16630:2026 – Metallic materials - Sheet and strip - Hole expanding test is an international standard published by ISO (International Organization for Standardization). It specifies a reliable method for determining the hole expansion ratio of metallic sheet and strip materials, particularly for thicknesses ranging from 1.2 mm to 6.0 mm and widths of at least 90 mm. The main purpose of the hole expanding test is to assess the formability of sheet metals, especially their suitability for forming flanges through operations such as bending or stretching.
