ISO 16417:2020

Overview

ISO 16417:2020 - Earth‑moving machinery - Hydraulic breakers - Terminology and commercial specifications defines standardized terminology and the required commercial specification content for hydraulic breakers used as attachments on carriers (e.g., excavators, backhoe loaders, skid steer and compact loaders as per ISO 6165) or mounted on rigs, pedestal booms, demolition robots, etc. The standard covers percussive hydraulic attachments used to break rock, concrete, brickwork and asphalt. It explicitly excludes pneumatic, thermomechanical or electromagnetic breakers and portable/hand‑held units.

Key topics and requirements

ISO 16417:2020 focuses on clear, consistent technical language and the data fields that should appear in product literature and specifications:

• Terms and definitions for components and assemblies (carrier, attachment, hydraulic breaker, power cell, piston, tool, bracket, housing, accumulator, piston control valve, etc.).
• Types and classifications based on mount direction (side/top), housing (open/closed) and mount method (direct or mounting adapter).
• Nomenclature and diagrams showing breaker parts and power‑cell variants (oil‑driven, oil+nitrogen).
• Mass definitions such as carrier operating mass, breaker operating mass, and breaker mass.
• Working condition parameters including hydraulic flow rate (l/min), operating pressure range (MPa), maximum allowed return/back pressure (MPa), and hydraulic fluid temperature range (°C).
• Dimensional definitions (overall length, length without tool, power cell length, effective/working tool length, tool/shank diameter, overall width/top & bottom, power cell widths) with reference figures.
• Commercial specification content required for manufacturer and product information. Required product fields include model/type, carrier operating mass range, breaker and operating mass, flow rate range, impact rate (BPM - 1 BPM = 1/60 Hz), dimensional data (mm) and other performance limits.

Applications and who uses the standard

ISO 16417 is practical for:

• Manufacturers and OEMs preparing datasheets, product catalogs and technical specifications for hydraulic breakers.
• Procurement teams and specifiers who need consistent, comparable product information for tenders and purchase decisions.
• Design and field engineers ensuring compatibility between carriers and breaker attachments (hydraulic flow/pressure and mounting).
• Regulatory and compliance personnel documenting product characteristics for regional markets.
• Aftermarket suppliers and service organizations for ordering replacement tools, mounting adapters and maintenance parts.

Using ISO 16417 improves clarity in product listings, interoperability between carriers and attachments, and reduces specification errors during procurement and equipment integration.
