DIN EN ISO 11850 2022-09 PDF

Full title and description

STB DIN EN ISO 11850 2022-09 — DIN adoption of EN ISO 11850:2011 with amendments A1:2016 and A2:2022. Title (short): "Machinery for forestry — General safety requirements". This document is the German/European (DIN / EN) publication of ISO 11850 including the two recent amendments, published in September 2022.

Abstract

ISO 11850 specifies general safety requirements for self-propelled forestry machines and machines configured as forestry machines. It addresses significant hazards, hazardous situations and events common to fellers, bunchers, delimbers, forwarders, log loaders, skidders, processors, harvesters, mulchers and multi-function versions of these machine types when used as intended and under reasonably foreseeable misuse. The standard does not replace machine‑specific hazard requirements or cover certain topics such as chain shot, some aspects of vibration/noise measurement setups, or hazards specific to certain attachments. The 2016 and 2022 amendments update and clarify specific requirements (for example access, removable covers and maintenance access).

Scope

Applies to the general safety design, construction and use of self-propelled forestry machines and machines configured as forestry machines. The standard covers common hazards and hazardous situations encountered across machine types (fellings, forwarding, loading, processing, mulching, etc.), and provides overarching safety requirements to be used alongside machine-specific standards and national regulations. It is intended for use by manufacturers, designers and conformity assessors as part of a safety/risk reduction program but does not replace specific requirements for particular attachments or all specialized hazards.

Key topics and requirements

• General safety objectives for machine design, guarding and protective measures (operator protection, control layout, visibility and ergonomics).
• Safe access and maintenance requirements for operator stations and maintenance locations; clarification and updates introduced by amendments (A1/A2) regarding access openings and removable covers.
• Requirements for removable covers and hand-removable elements (mass/size limits and secure fastening to reduce risk during inspection/maintenance).
• Risk reduction measures: guarding, interlocks, emergency stop provisions and protective structures appropriate to forestry machine hazards.
• Reference to related ISO standards for terminology and specific technical details (for example ISO 6814 for machine definitions and ISO 2867 for access/openings in some referenced clauses).

Typical use and users

Used by forestry machine manufacturers and OEM design teams to ensure machines meet general safety expectations; by safety and compliance engineers during risk assessments; by testing and certification bodies to verify conformity with general safety requirements; and by procurement or fleet owners to define contractual safety expectations. Regulators and notified bodies may reference the standard when assessing machine safety for market access.

Related standards

Commonly used together with: ISO 6814 (terminology and definitions for forestry machinery), ISO 2867 (access openings and related dimensional/mass considerations where referenced), machine‑specific ISO or EN standards covering particular hazards or attachments, and national/adopted EN versions (DIN EN ISO) for legal/regulatory alignment. Users should consult the normative references listed in the standard for the complete set.

FAQ

Q: What is this standard?

A: DIN EN ISO 11850:2022-09 is the German/European publication of ISO 11850 ("Machinery for forestry — General safety requirements") including amendments A1:2016 and A2:2022; it provides overarching safety requirements for self-propelled forestry machines.

Q: What does it cover?

A: It covers general safety design and operational requirements common to many types of forestry machines (fell ers, bunchers, delimbers, forwarders, loaders, skidders, processors, harvesters, mulchers), addressing hazards, access and maintenance considerations, guarding and other risk‑reduction measures. It does not replace machine‑specific standards or cover certain specified exclusions noted in the standard.

Q: Who typically uses it?

A: Machine manufacturers, design and safety engineers, conformity-assessment and test bodies, procurement teams, fleet operators and regulators use the standard to specify and verify general safety requirements for forestry machinery.

Q: Is it current or superseded?

A: The edition represented by DIN EN ISO 11850:2022-09 is a current DIN/EN adoption of ISO 11850:2011 plus amendments A1:2016 and A2:2022; ISO indicates the base standard (ISO 11850:2011) with amendments remains the active normative text and work on a revised edition (committee draft) is under development. Users should check the latest committee/ISO status for any newer revisions.

Q: Is it part of a series?

A: It is a general safety requirements standard within the family of forestry machinery standards (other ISO/EN documents address terminology, machine-specific requirements or measurements). It is intended to be used together with machine-specific standards and the normative references listed in ISO 11850.

Q: What are the key keywords?

A: forestry machines, machine safety, operator access, maintenance access, removable covers, EN ISO 11850, DIN adoption, risk reduction.
