ISO 11886:2025

Overview - ISO 11886:2025 (Drilling and foundation machinery - Commercial specifications)

ISO 11886:2025 defines the content and structure of commercial specifications for drilling and foundation machines used in civil and geotechnical engineering. The second edition covers mobile drill rigs, foundation and piling equipment, diaphragm walling machines, jetting/grouting/injection units, and interchangeable auxiliary equipment. It explains terminology, machine types, working methods and the main components that should be specified in contracts, data sheets and procurement documents.

Note: ISO 11886:2025 excludes machines specifically designed for mining applications and horizontal directional drilling (HDD) machines - HDD is covered by ISO 21467.

Key topics and technical requirements

ISO 11886 organizes requirements and guidance into clear sections that buyers and manufacturers can adopt in commercial specifications:

• Terms and definitions / Nomenclature - standardized vocabulary for components, methods and tools.
• Machine classes and methods - mobile drill rigs, piling machines, diaphragm wall grabs/cutters, jet/grout units.
• Main characteristics - operating mass, dimensions, stability, drill rod characteristics, feed and rotation systems.
• Power and transmission - engine, powertrain, hydraulic system and fluid system specification.
• Undercarriage and mobility - track vs tyre options, travel, steering and braking.
• Accessory systems - winches, hammers (impact and vibratory), clamping devices, casing oscillators/rotators.
• Performance and safety - noise, safety devices, drilling fluid specifications and operational limits.
• Annexes - normative dimensions for carriers and attachments and an informative equipment list to support consistent specifications.

ISO 11886 focuses on what information should be provided in commercial documents rather than prescribing specific design values, enabling consistent comparison across suppliers.

Practical applications and users

ISO 11886:2025 is intended for professionals who create, evaluate or use commercial specifications for foundation and drilling equipment:

• Equipment manufacturers preparing product data sheets and tender responses
• Procurement teams writing technical specifications for tenders and contracts
• Contractors, geotechnical and civil engineers selecting machines for projects
• Rental companies and fleet managers comparing machine capabilities
• Certification and conformity assessment bodies referencing standardized nomenclature

Using ISO 11886 helps ensure clarity in procurement, more accurate equipment matching to project methods (piling, diaphragm walling, jet/grout), and easier supplier comparisons.
