Full title and description

ISO 10207:1991/Cor 1:1991 — Rock drilling equipment — Rope threaded drill steel equipment for percussive drilling, nominal sizes 22 mm to 38 mm — Technical Corrigendum 1. This corrigendum is a one-page technical correction that applies to the base publication ISO 10207:1991, which specifies basic dimensions for rope-threaded drill steel equipment (hexagonal shank rods, extension rods, coupling sleeves and drill bits) for percussive drilling in the listed nominal sizes.

Abstract

This document is a technical corrigendum (Corrigendum 1, April 1991) to ISO 10207:1991. It issues a short correction to the original standard (ISO 10207:1991) to clarify or amend text or dimensional details for rope-threaded drill steel equipment in the nominal sizes 22 mm to 38 mm. The corrigendum itself is published as a single-page amendment and is to be used in conjunction with the base standard.

General information

• Status: Published (technical corrigendum to ISO 10207:1991).
• Publication date: April 1991 (ISO 10207:1991/Cor 1:1991).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 73.100.30 — Equipment for drilling and mine excavation.
• Edition / version: Edition 1 (Corrigendum to ISO 10207:1991).
• Number of pages: 1 (corrigendum document).

Scope

The corrigendum applies to ISO 10207:1991, which specifies the basic dimensions and related details for rope-threaded drill steel equipment used in percussive rock drilling for nominal sizes from 22 mm up to 38 mm. The corrigendum provides technical corrections to the original text or tables of ISO 10207:1991 and should be read together with that base standard. Users must apply the corrigendum's changes alongside the original standard's provisions.

Key topics and requirements

• Correction to published text or dimensional tables in ISO 10207:1991 (technical corrigendum format; one page).
• Applies to rope-threaded drill steel equipment for percussive drilling (nominal sizes: 22 mm, 25 mm light, 25 mm, 28 mm light, 28 mm, 32 mm light, 32 mm, 38 mm as in national/adopted listings).
• Covers primary items: hexagonal shank rods, extension rods, coupling sleeves and compatible drill bits (dimension and interchangeability details are in the base standard).
• Issued by ISO/TC 82 (Technical Committee for mining and associated equipment).
• Intended as a technical correction — not a full revision; it modifies the existing published clauses/tables where necessary.

Typical use and users

Manufacturers and suppliers of drill steel and drill components, mining and quarrying equipment engineers, drilling contractors, testing laboratories, and national standards bodies use ISO 10207:1991 together with this corrigendum to ensure dimensional compatibility and interchangeability of rope-threaded drill steels for percussive drilling. Procurement and quality assurance teams refer to the corrected values when specifying or inspecting components.

Related standards

Related documents include the base standard ISO 10207:1991 (the main publication this corrigendum amends) and other ISO standards on rope threads and drilling equipment produced by ISO/TC 82, for example ISO 10208:1991 (left-hand rope threads) and ISO 8866 series (rotary core diamond drilling equipment) which cover related dimensions and thread forms for drilling tools. National adoptions and identical adoptions (e.g., SS-ISO 10207:2020) reproduce the ISO text for local use.

FAQ

Q: What is this standard?

A: ISO 10207:1991/Cor 1:1991 is a one-page technical corrigendum (Corrigendum 1, April 1991) that corrects or clarifies elements of ISO 10207:1991 — the ISO standard on rope-threaded drill steel equipment for percussive rock drilling.

Q: What does it cover?

A: The corrigendum makes specific technical corrections to the published ISO 10207:1991 text or tables; the base standard defines basic dimensions and interoperability for rope-threaded drill steel equipment (hexagonal shank rods, extension rods, coupling sleeves, drill bits) for nominal sizes between 22 mm and 38 mm. The corrigendum must be applied together with the base standard.

Q: Who typically uses it?

A: Manufacturers of drill steel and accessories, drilling contractors, mining and quarry engineering teams, procurement and QA professionals, and standards/technical committees concerned with drilling-equipment interchangeability.

Q: Is it current or superseded?

A: The corrigendum was published in April 1991 to amend ISO 10207:1991; the base ISO 10207:1991 has been confirmed in ISO’s review cycle (the ISO entry shows the 1991 standard remained active/confirmed in later ISO reviews). Users should check ISO or their national body for any later revisions or withdrawals of the base standard.

Q: Is it part of a series?

A: It is a corrigendum to ISO 10207:1991. ISO/TC 82 has produced several related standards and corrigenda on drilling equipment and thread forms (for example ISO 10208 and ISO 8866 series). National bodies may carry identical/adopted versions.

Q: What are the key keywords?

A: Rope-threaded drill steel, drill rods, coupling sleeves, hexagonal shank, percussive drilling, nominal sizes 22–38 mm, corrigendum, ISO 10207.
