Full title and description

ISO 10485:1991 — Cone proof load test on nuts. This International Standard specifies the cone proof load test method, the conditions of the load test and the associated acceptance criteria for nuts (nominal thread diameters in the specified range).

Abstract

A short International Standard (Edition 1, 1991) that defines a cone proof load test procedure for assessing the proof-load behaviour of nuts. The document sets the test conditions, the range of applicable thread diameters and the product/property classes to which the test applies.

General information

• Status: Withdrawn.
• Publication date: November 1991 (1991).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 21.060.20 (Mechanical systems and components for general use — Fasteners).
• Edition / version: Edition 1 (1991).
• Number of pages: 2.

Scope

Defines the cone proof load test for nuts under specified conditions. The standard applies to nuts with nominal thread diameters within the small-to-medium metric range (example values given in the standard) and addresses product grades and property classes to which proof load testing is relevant. It specifies the test arrangement, load application and the acceptance criteria used to determine whether a nut meets the proof-load requirements.

Key topics and requirements

• Definition and purpose of the cone proof load test (proof-load verification for nuts).
• Range of applicable nominal thread diameters and thread types covered by the procedure.
• Product grades and property classes for which the test is specified (examples and limits appear in the text).
• Test apparatus and cone geometry, test load application and measurement of deformation/acceptance criteria.
• Reference to the responsible technical committee (ISO/TC 2/SC 12) and positioning among fastener mechanical-property standards.

Typical use and users

Manufacturers of nuts and fasteners, independent testing laboratories, quality and product assurance engineers, procurement specialists who need to verify mechanical proof load behaviour, and standards bodies referencing test methods for product specifications. Typical use is for type testing, incoming inspection or quality verification where proof load behaviour is specified.

Related standards

ISO 10485:1991 sits within the body of fastener standards and is related to mechanical-property and proof-load standards such as the ISO 898 series (Mechanical properties of fasteners — including the parts covering nuts and proof-load values). There are also regional/adopted documents referencing ISO 10485 (for example later EN/BS adoptions).

FAQ

Q: What is this standard?

A: ISO 10485:1991 is an International Standard that specifies the cone proof load test for nuts — a short technical method document first published in 1991.

Q: What does it cover?

A: It covers the procedural details of the cone proof load test, the conditions under which the test is carried out, the range of nuts (by nominal thread diameter and product/property classes) to which the test applies, and the acceptance criteria.

Q: Who typically uses it?

A: Fastener manufacturers, test laboratories, quality engineers and procurement/specification authors who need a standardized method to verify proof-load capability of nuts.

Q: Is it current or superseded?

A: ISO 10485:1991 is listed as Withdrawn in the ISO catalogue. Users should consult current fastener mechanical-property standards (for example the ISO 898 series and later revisions) for up-to-date requirements.

Q: Is it part of a series?

A: It is part of the broader family of fastener standards developed under ISO/TC 2/SC 12 and is related to other mechanical-property standards for fasteners (for example parts of ISO 898, which cover nuts and proof-load/property classes).

Q: What are the key keywords?

A: Nuts; cone proof load; proof load; fastener testing; nut proof testing; ISO 10485; mechanical properties.
