Overview

EN 15436-2:2015 is the CEN European Standard that specifies test methods and measurement accuracies for the performance assessment of road service area maintenance equipment. It applies to machinery mounted on self‑propelled carrying vehicles and designed for:

• grass‑cutting and brush‑cutting (articulated‑arm grass cutters / brushcutters and in‑line flail mowers), and
• mechanical plant‑cutting (trees, saplings, bushes).

This Part 2 standard focuses on how to measure and report the technical performance of new production machines (head of series). It does not cover collection or transportation of shredded material.

Key topics and technical requirements

EN 15436-2 defines measurement procedures, required accuracies and reporting formats for core performance domains:

• Cutting specifications - measurement of cutting width and cutting height for different head types. Example: cutting width is measured to an accuracy of ±0.01 m.
• Kinematic properties - ranges and articulation metrics (horizontal/vertical ranges, embankment and ditch reach, offsets, clearance and rotation angles) for articulated arms and in‑line mowers.
• Weights and dimensions - transport dimensions (height, width, length) and total machine weight checks.
• Power and drive checks - protocols and calculations to determine power delivered to cutting tools for machines driven by:
  • PTO shafts (mechanical/hydraulic transmission),
  • carrying‑vehicle hydraulics. Annex D provides a normative test protocol for power measurement at the tool.
• Performance characteristics - definitions and methods to determine maximum continuous and instantaneous power, cutting tool speed, torque, circumferential speed and kinetic energy.
• Presentation of results - informative annexes provide standardized result formats for different machine types.

The standard also cross‑references EN 15436‑1:2008 (Terminology) and forms part of the EN 15436 series (Parts 1–4).

Practical applications and users

EN 15436-2:2015 is used by:

• Manufacturers and R&D teams to validate machine performance and demonstrate compliance during design and production validation.
• Test laboratories and inspection bodies to carry out repeatable, accredited performance testing.
• Public agencies and road authorities for procurement specifications, acceptance testing and performance verification of roadside maintenance fleets.
• OEMs and component suppliers to size powertrains and verify hydraulic/PTO interfaces.
• Certification and conformity assessors preparing reports tied to delivery acceptance (see EN 15436‑4).

Using this standard ensures consistent, comparable performance data for equipment used in roadside vegetation management, vegetation clearance and safety maintenance.

The cutting rotor stop time is measured with an accuracy of ± 0,5 s and expressed in seconds (s). A distinction is made between the value of the stop times for open hydraulic circuits and for closed hydraulic circuits. 5 Kinematic properties check 5.1 General In their design structure, all these machines have the same constituent elements, i.e. a frame, articulated arms and a tool. Whatever the shape and size of the components and any accessories that may be used, there is always an articulation between the frame and the primary arm. The articulation which is very close to the frame is used to define three reference planes for the machine. The kinematic properties of the different machines are then defined with respect to these reference planes. See the definitions according to EN 15436-1:2008, 5.1 to 5.6. Given that the height, in relation to the ground plane of the primary arm–frame articulation changes the geometry of certain operating positions significantly, the horizontal reference plane of the machine is positioned at a height ZP from the ground specified by the manufacturer. This height can vary. SIST EN 15436-2:2015
