Overview

EN 15694:2009+A1:2015 (CEN) - "Agricultural and forestry tractors - Passenger seat - Requirements and test procedures" sets minimum safety, dimension and test requirements for tractors that carry one passenger in addition to the driver. The standard covers space and support requirements, seat belt and restraint provisions, roll‑over protective structure (ROPS) test procedures and the information the tractor manufacturer must supply (including operator's manual guidance).

Keywords: EN 15694:2009+A1:2015, passenger seat, agricultural and forestry tractors, ROPS, seat belt, test procedures, tractor manufacturer.

Key topics and technical requirements

• Scope: Applies when provision is made for carrying one additional person on agricultural or forestry tractors; covers both road and field use conditions.
• Seat location & mounting: Passenger seat must not create driving impediments and must be securely attached to a structural member of the tractor, platform or ROPS.
• Dimensions & comfort:
  • Minimum seat width: 400 mm
  • Minimum seat depth: 300 mm
  • Backrest height: at least 200 mm
  • Seat cushion: padded or elastic material required
• Vertical clearance: Minimum 920 mm above the passenger seat; may be reduced to 800 mm with adequate padding where tractor design prevents 920 mm. Rear/sides limited only by a radius ≤ 300 mm.
• Seat belt / restraint: A restraint system must be provided in accordance with the ISO 3776 series (anchorage location and strength).
• Foot rest & grab handles: Required to aid access and maintain passenger position.
• ROPS & testing:
  • Passenger protection by driver ROPS or an additional structure if passenger use during field operations is intended.
  • Where passenger use is limited to roads, a visible safety sign and operator's manual instruction must prohibit field‑use.
  • Test procedures and acceptance criteria for ROPS and passenger protection are specified (see Annexes covering Passenger Deflection‑Limiting Volume (PDLV), Passenger Seat Index Point (SIPp), interference zones, and sequences of dynamic/static tests such as longitudinal loading, crushing and side loading).
• Manufacturer information: Required instructions and warnings must be included in the operator's manual and on/near the seat when use is restricted.

Applications / Who uses this standard

• Tractor manufacturers - to design and certify passenger seats and ROPS compliance.
• Component suppliers - for seat assemblies, belts and mounting hardware.
• Test laboratories - to perform ROPS and seat‑clearance tests per the standard’s procedures.
• Regulators and inspectors - to assess conformity and safe use labeling.
• Fleet managers and dealers - to verify safe passenger transport options and operator information.

Related standards (normative references)

EN 15694 references key ISO standards for testing and anchorage, including:

• ISO 3463, ISO 5700, ISO 12003‑1/2 (ROPS test methods)
• ISO 3776‑1 / ISO 3776‑2 (seat belt anchorage location and strength)
• ISO 5353 (seat index point concepts)

Practical value: EN 15694:2009+A1:2015 ensures repeatable, performance‑based tests and clear manufacturer information so passenger transport on tractors is managed without reducing driver protection, while aligning with existing ROPS and restraint standards.

Deflection limiting volume, sequence of tests and acceptance criteria for the passenger seat (see 5.2) B.1 Passenger Deflection Limiting Volume (PDLV) The passenger deflection limiting volume (PDLV) is established using the passenger seat index point (SIPp), as defined in 3.2 according to the dimensions reported in Figure B.1. Front view Right side view
Figure B.1 — Passenger deflection limiting volume (PDLV) It is also allowed to rotate forward and rearward and to each side about the SIPp not more than 15° with respect to transversal and longitudinal reference planes (Figure B.2). SIST EN 15694:2012+A1:2016

Figure B.2 — Rearward, forward and lateral rotation In addition, the upper portion of the PDLV, as illustrated in Figure B.3, is allowed to flex forward and rearward an additional 15° maximum with respect to transversal reference plane. This flexion movement is around a flexion axis (FA) located as reported in Figure B.3.

Key a rearward flexion b rearward rotation c forward flexion d forward rotation Figure B.4 — Overall motions in rearward and forward directions (right side view) B.2 Passenger seat index point (SIPp) In order to apply the passenger deflection limiting volume it is necessary to define a passenger seat index point (SIPp). For its definition, ISO 5353:1995 shall be applied. B.3 Allowable interference B.3.1 General During the ROPS test for agricultural or forestry tractors, a maximum interference between operator clearance zone (OCZ) and passenger deflection limiting volume (PDLV) is allowed. In particular the OCZ, defined in relation to the operator seat index point (SIPo)1, has been divided into three interference zones as follow (Figure B.5): — the first zone extends for 350 mm (plane a in Figure B.5) in longitudinal direction from the back of the operator clearance zone (point G in Figure B.5); — the second zone is enclosed among the end of the previous one (plane a) and a transversal plane (plane b in Figure B.5) located at 400 mm from point B in longitudinal direction;

Key 1 tractor longitudinal median plane Figure B.5 — Interference zones For each of the interference zones previously defined a maximum allowable interference between OCZ and PDLV has been set. The reference interference zone is the one which contains the projection of SIPp on the tractor longitudinal median plane (see Figure B.5). If this projection coincides with one of the division planes (a or b) the reference interference zone should be indifferently one of the two zones sharing the division plane. With reference to Figure B.6 a minimum horizontal distance (A) between SIPp and SIPo shall be evaluated. SIST EN 15694:2012+A1:2016

Key A horizontal distance between SIPp and SIPo measured on a vertical plane orthogonal to the longitudinal median plane of the tractor passing through SIPp
h vertical distance between SIPp and SIPo measured on a vertical plane orthogonal to the longitudinal median plane of the tractor passing through SIPp
angular deflection measured between vertical median plane of the tractor and vertical median plane of PDLV Figure B.6 — Nomenclature for interference determination - Rear view (on the left) and top view (on the right) B.3.2
Interference evaluation procedure The interference evaluation procedure is defined as follows: — determination of the operator seat index point (SIPo); — determination of the passenger seat index point (SIPp); — determination of the three interference zones on the operator clearance zone (see Figure B.5); — determination of the reference interference zone by the projection of the SIPp on the longitudinal median plane of tractor; — determination of the angular deflection () of the passenger seat with respect to the moving direction of the tractor; — measurement of the vertical distance (h) between SIPo and SIPp; — measurement of the transversal distance (A) between SIPo and SIPp during all the ROPS test; — comparison and verification of the value of A, determined at previous step, with respect to the values reported in the following Tables B.1, B.2 and B.3.
