This document also applies to pedestrian controlled trucks with foldable platform when used in ride-on mode.
Pedestrian-controlled trucks without an operator on the platform and pedestrian-propelled trucks are not covered by this document.
Where specific requirements in this part are modified from the general requirements in EN 16842 1, the requirements of this part are truck specific and intended to be used for self-propelled industrial stand-on pallet-stacking trucks.

SIST EN 16842-11:2026 is the Slovene standard for visibility test methods and verification for powered industrial trucks, Part 11 for pallet stacking trucks (rider controlled). It specifies how to check 360° visibility for self-propelled industrial rider-controlled pallet-stacking trucks without a load, and it is intended to be used with EN 16842-1. It is written for people who design, test, verify or specify these trucks.
What does SIST EN 16842-11:2026 specify?
SIST EN 16842-11:2026 covers 360° visibility of self-propelled industrial rider-controlled pallet-stacking trucks in the operating condition without a load. It also applies to pedestrian-controlled trucks with a foldable platform when they are used in ride-on mode. Pedestrian-controlled trucks without an operator on the platform and pedestrian-propelled trucks are outside its scope.
SIST EN 16842-11:2026 says that where this part changes the general rules in EN 16842-1, the truck-specific requirements in Part 11 apply to self-propelled industrial stand-on pallet-stacking trucks. It addresses hazards and reasonably foreseeable misuse that affect the operator’s visibility.
The document is organized into clauses 1 to 9:
- Scope
- Normative references
- Terms and definitions
- Truck configuration
- Test equipment
- Test procedures for direct visibility
- Acceptance criteria
- Test report
- Information for use
Clauses 6 and 7 contain the main test method and pass/fail criteria. Figures 1 to 6 show the operator reference points and test paths, and Tables 1 and 2 set the required viewing directions and acceptance criteria for the two operator orientations.
What are the key requirements of SIST EN 16842-11:2026?
Test setup and truck condition
SIST EN 16842-11:2026 uses the EN 16842-1 test configuration rules, with one key limit: the load-carrying surface of the fork arms, measured at the heel, is positioned up to 120 mm above the floor. In practice, this keeps the visibility test tied to a defined truck geometry instead of a working load condition.
The standard follows EN 16842-1 for test equipment, but trucks with foldable operator platforms are excepted from requirement 5.2.2 of EN 16842-1. That matters because the lighting equipment can move outside the plan-view outline in some test positions on these trucks.
How the operator position is set
For stand-on trucks, the lighting equipment is positioned relative to the standing index point (STIP). The STIP is established from the operator’s foot positions and ankle pivot points, then recorded against a permanent truck feature. If the truck has more than one STIP, all of them are evaluated.
SIST EN 16842-11:2026 also allows an adjusted STIP (ASTIP) to represent normal body movement during operation. For sit-on trucks, the lighting equipment is positioned relative to the seat index point (SIP), with the seat placed at the nearest mid-adjustment position. In practice, this ensures the visibility test reflects the operator’s real operating posture.
Visibility testing and acceptance
SIST EN 16842-11:2026 uses floor-laid test paths around the truck, identified as P1 to P9, and the measurement procedure in EN 16842-1 Clause 6. The direct visibility tests are then checked against the criteria in Tables 1 and 2, depending on whether the operator faces the line of travel or a right angle to it.
The direct visibility checks cover:
- travelling visibility
- manoeuvring visibility
- fork arm visibility
These checks matter because they separate normal travel sight lines from close-quarters manoeuvring and fork-tip visibility, which are different risks in real use. Indirect visibility and auxiliary equipment follow EN 16842-1 Clause 7 and must also be assessed where applicable.
The test report follows EN 16842-1 Clause 8.2, and the handbook must warn about operating conditions where the load or attachment can restrict visibility. That gives users the information they need to judge whether the truck remains suitable for the intended task.
What terms does SIST EN 16842-11:2026 define?
Truck profile - For stand-on straddle trucks, this is the contour defined by the largest rectangular width and length parallel to the truck’s longitudinal axis, including the front vertical surface of the outriggers, while excluding fork blades and external projections.
Standing index point (STIP) - The reference point for the standing operator position used to locate the lighting equipment during visibility testing.
Adjusted STIP (ASTIP) - A permitted alternate position around the STIP that represents normal operator movement during the test.
Seat index point (SIP) - The reference point used to position the lighting equipment for a seated operator.
Test body - The obstacle-like target used to check direct visibility in the test procedure.
Test screen - The screen used in the travelling visibility check where the standard calls for a flat target instead of a test body.
Who uses SIST EN 16842-11:2026?
SIST EN 16842-11:2026 is used by manufacturers of pallet stacking trucks, test laboratories, and engineering teams that verify operator visibility during design validation. It is also useful to quality managers and buyers who need to compare truck configurations and understand how visibility is measured. Fleet owners and service teams use the handbook information when loads or attachments can reduce visibility in service.
Which standards are used with SIST EN 16842-11:2026?
EN 16842-1:2018 provides the general visibility requirements, test equipment rules, measurement procedure, indirect visibility procedure and test report format used with this part.
EN ISO 3691-1:2015 provides the general safety requirements and verification rules for self-propelled industrial trucks, and it is also the basis for the handbook note on visibility restrictions from loads or attachments.
ISO 5053-1:2020 provides the vocabulary for industrial truck types used by this document.
What does the SIST EN 16842-11:2026 document contain?
SIST EN 16842-11:2026 contains the operator reference-point figures, the test-path figures, and two criteria tables that distinguish the two operator orientations. It also contains the procedure for setting the STIP, ASTIP and SIP, plus the measurement method for direct and indirect visibility.
For practical use, the document gives labs and manufacturers a repeatable way to set up the truck, place the simulated eye position, run the visibility checks, and record the results. The report and handbook clauses support testing, design review, and technical documentation.
