CEN/TC 144 - Tractors and machinery for agriculture and forestry

This document specifies requirements and the means for their verification for the design and performance of aerial fixed wing and rotary aircraft spray systems for agriculture, forestry, turf, and vegetation control in transport access ways (such as gas and electric lines) with regard to minimizing the potential risk of environmental contamination during use, including misuse foreseeable by the manufacturer.
It is intended to be used with ISO 16119-1:2013, which gives general requirements common to all the sprayer types covered by ISO 16119. When requirements of this document are different from those stated in ISO 16119-1:2013, the requirements of this document take precedence over the requirements of ISO 16119-1:2013 for machines within the scope of this document.
This document does cover safety of aerial spray equipment not covered by ISO 4254 series.
This document is not applicable to sprayers manufactured before the date of its publication, or unmanned aerial vehicles (such as drones).

This document applies to front and rear-mounted implements on agricultural or forestry tractors, self-propelled machines, trailers or on towed machinery.
This document specifies the requirements for lighting and light-signalling devices to be installed on the implement for safe on-road use.
NOTE   Mounted implements are considered to be interchangeable equipment and become part of the tractor, self-propelled machine, trailer or towed machine to which they are attached.
This document describes the installation of lighting and light signalling devices on mounted implements when the vehicle's lighting and signalling devices cannot comply with the applicable road regulation requirements.

This document sets out general principles for the design and development of safety-related parts of control systems (SRP/CS) on tractors used in agriculture and forestry and on self-propelled ride-on machines and mounted, semi-mounted and trailed machines used in agriculture. It can also be applied to mobile municipal equipment (e.g. street-sweeping machines).
This document is not applicable to:
—          aircraft and air-cushion vehicles used in agriculture;
—          lawn and garden equipment.
This document specifies the characteristics and categories required of SRP/CS for carrying out their safety-related functions. It does not identify performance levels for specific applications.
NOTE 1    Machine specific type-C standards can specify performance levels (AgPL) for safety-related functions in machines within their scope. Otherwise, the specification of AgPL is the responsibility of the manufacturer.
This document is applicable to the safety-related parts of electrical/electronic/programmable electronic systems (E/E/PES), as these relate to mechatronic systems.

It does not address hazards related to electric shock, fire, smoke, heat, radiation, toxicity, flammability, reactivity, corrosion, release of energy, and similar hazards, unless directly caused by malfunctioning behaviour of E/E/PES safety-related systems. It also covers malfunctioning behaviour of E/E/PES safety-related systems involved in protective measures, safeguards, or safety-related functions in response to non-E/E/PES hazards.
Examples included within the scope of this document:
—          SRP/CS limiting current flow in electric hybrids to prevent insulation failure/shock hazards;
