ISO 3552-2-1992 PDF

Full title and description

Rotary core diamond drilling equipment — System B — Part 2: Inch units. This International Standard (ISO 3552-2:1992) defines nomenclature, leading dimensions and basic characteristics for rotary core diamond drilling equipment in System B expressed in inch units, to ensure interchangeability of components such as drill rods and couplings, casing and core-barrel components for specified hole and core diameters.

Abstract

This part of ISO 3552 establishes the nomenclature and main dimensions (with tolerances) required to ensure interchangeability, within the limits of System B, of equipment including drill rods and couplings, fishing rods and couplings, casing tubes and accessories, core barrels, core bits, core lifters and reaming shells. It specifies sizes and characteristics for a range of equipment covering hole diameters from about 1.42 in to 5.74 in and corresponding core diameters from about 0.87 in to 4.72 in.

Scope

ISO 3552-2:1992 applies to rotary core diamond drilling equipment designated to System B and covers inch-based dimensions and tolerances for the listed equipment items to permit interchangeability. The standard gives designation rules, material considerations, dimensional and tolerance tables, mechanical characteristics and allowable straightness deviations for the relevant parts and assemblies used when coring with diamonds or other cutting materials.

Key topics and requirements

• Standardized nomenclature and designation numbers for System B components (rod, coupling, core-barrel, casing, bits, lifters, etc.).
• Main dimensional tables (inch units) for external and internal diameters of core barrels, casing and sediment tubes and related parts.
• Tolerances on dimensions and allowable straightness (runout/deflection) limits for parts to ensure interchangeability.
• Specified mechanical characteristics for selected components (strength and compatibility requirements).
• Designation format and reference numbering to identify parts manufactured to this part of ISO 3552.

Typical use and users

Used by manufacturers of diamond core drilling equipment, mining and exploration contractors, geological field services, procurement/specification engineers, testing laboratories and standards bodies. It is applied when designing, specifying, buying or verifying System B inch‑unit drilling components to ensure parts from different suppliers fit and perform together.

Related standards

ISO 3552 is a multi‑part series. Closely related is ISO 3552-1:1992 (Part 1: Metric units), which provides the same content for metric dimensions and is often used together with Part 2 when comparing or converting designs between unit systems. The standard was produced under ISO/TC 82 (mining and rock drilling equipment).

FAQ

Q: What is this standard?

A: ISO 3552-2:1992 is an international standard that specifies nomenclature, dimensions and tolerances for rotary core diamond drilling equipment in System B using inch units to ensure interchangeability of components.

Q: What does it cover?

A: It covers drill rods and couplings, fishing rods and couplings, casing tubes and accessories, core barrels, core bits, core lifters and reaming shells, giving dimensional tables, tolerances, mechanical characteristics and designation rules for specified hole and core diameter ranges.

Q: Who typically uses it?

A: Manufacturers, mining and exploration contractors, geotechnical engineers, procurement/specification teams and testing bodies that design, supply or verify compatible drilling components for System B inch‑unit applications.

Q: Is it current or superseded?

A: The published record shows ISO 3552-2:1992 as the first edition published in July 1992; lifecycle records list it as published/confirmed. Users should check with their national standards body or ISO for any amendments, confirmations or newer revisions before relying on it for regulatory or procurement decisions.

Q: Is it part of a series?

A: Yes — ISO 3552 is multi‑part. Part 1 covers metric units (ISO 3552-1:1992) and Part 2 covers inch units (this standard). Both parts are complementary for System B drilling equipment.
