ISO/TR 11071-2:2006 PDF

Overview

ISO/TR 11071-2:2006 (identical to ISO/TR 11071-2:2006) is a Technical Report that compares worldwide hydraulic lift (elevator) safety standards. It is an informative cross‑reference - not a normative standard - that documents similarities, differences and agreed points among major national and regional codes. The report covers both direct-acting and indirect (roped) hydraulic lifts and is intended to support standards writers, manufacturers, regulators and technical experts working toward harmonized safety requirements.

Key Topics and Technical Requirements

The report summarizes selected topics and provides tabulated comparisons across the referenced standards:

• Standards compared: CEN EN 81-2:1998; ASME A17.1:2004 & CSA B44:2004; Building Standard Law of Japan (BSLJ); Standards Australia AS 1735-1:2003 and AS 1735-3:2002.
• Terminology and definitions: reconciliation of CEN vs ASME/CSA terms (e.g., “lift” vs “elevator”, “jack/ram/plunger”, “hydraulic machine/driving machine”).
• Hydraulic design safety: approaches to safety of hydraulic components, including working pressure (WP) vs full load pressure (FLP) and the practical relation noted in the report (ASME WP ≈ 1.15 × CEN FLP).
• Driving machines and jacks: requirements for pumps, motors, cylinders, rams/plungers and driving‑machine classifications.
• Valves, piping and fittings: safety valves, non‑return/check valves, pressure relief devices and rupture protection.
• Ropes, chains, capacity and loading: roping ratios, load classifications and safety factors.
• Spaces, clearances and protection: required clearances, protection against free‑fall, excessive speed and creeping.
• Electrical devices: electrical protective devices and controls relevant to hydraulic systems.
• Annexes: comparative tabulations and normative references for detailed cross‑checks.

Practical Applications and Users

This Technical Report is useful for:

• Standards committees and regulators seeking to harmonize or revise lift safety codes.
• Lift manufacturers and designers comparing compliance obligations across markets.
• Safety engineers, inspectors and maintenance teams who need to interpret different national requirements.
• Consultants and building authorities integrating lift requirements with building codes and other mechanical/electrical standards.

The report emphasizes that hydraulic lifts must also comply with other relevant standards (structural, mechanical, electrical), building codes and environmental regulations.
