SIST EN 62841-4-1:2020/kFprAB:2026 is the Slovenian draft amendment for the chain saw safety part of the electric motor-operated hand-held tools, transportable tools and lawn and garden machinery series, published by SIST. It sets out a specific mechanical safety change for chain saw handle placement, updates the European normative references, and refreshes the link to the EU Machinery Directive for users working on design, testing, and conformity assessment.

What does SIST EN 62841-4-1:2020/kFprAB:2026 specify?

SIST EN 62841-4-1:2020/kFprAB:2026 is an amendment to the chain saw safety standard. It modifies Clause 19 on mechanical hazards, replaces Annex ZA on normative references, and replaces Annex ZZ on the relationship with Directive 2006/42/EC.

The practical focus is on keeping hands farther from the cutter blade and on aligning the text with the legal and referenced-test framework used for chain saws.

Part of the document	What it covers
Clause 19 modification	Front handle distance and front hand barrier requirements for mechanical hazards
Annex ZA	Normative references to international publications and their European publications
Annex ZZ	Relationship between the European Standard and Directive 2006/42/EC

What are the key requirements of SIST EN 62841-4-1:2020/kFprAB:2026?

SIST EN 62841-4-1:2020/kFprAB:2026 tightens the handle-clearance rules used to control contact risk with the cutter blade. It also clarifies how the clearances are measured and how the front hand barrier is treated.

Front handle distance in Clause 19

For most categories, the front handle must be positioned so the shortest distance from the nearest cutting edge of the cutter blade to the rear side of any handle is at least 120 mm. For Category 1, the shortest distance between the front of the handle grip and the nearest blade tooth must also be at least 120 mm.

In practice, this means a manufacturer has to check the geometry of the chain saw, not just the nominal handle location. The rule is intended to reduce the chance that a hand reaches the cutting zone during use.

Measurement path and front hand barrier

The document requires the distance to be measured along the shortest path. Where a front hand barrier is present for the categories in Table 101, the distance is measured from the back of the handle, via the barrier edge, to the nearest cutting edge of the cutter blade.

The front hand barrier itself must not have openings with a minor dimension greater than 10 mm. That matters because openings can create a path for fingers or reduce the protective effect of the barrier.

Compliance check

Compliance is checked by inspection and by measurement. In practice, this means the requirement is verified by looking at the construction and measuring the relevant distances and openings on the actual product or representative sample.

Legal and reference framework

Annex ZZ links the standard to the essential requirements of Directive 2006/42/EC. It states that, once cited in the Official Journal of the European Union, compliance with the normative clauses listed in Table ZZ.1 can give presumption of conformity within the scope of the standard.

Annex ZA updates the normative references used by the document. For users, this tells you which referenced test or method standards need to be followed when demonstrating compliance.

What terms does SIST EN 62841-4-1:2020/kFprAB:2026 define?

• Chain saw - the machine type covered by this part, used for cutting with a cutter blade.
• Mechanical hazards - the safety risks from moving and cutting parts that Clause 19 addresses.
• Front hand barrier - a protective barrier in front of the handle that affects the distance measurement to the blade.
• Category 1 - a product category in Table 101 that has its own handle-to-blade distance wording.
• Normative reference - a referenced publication whose content becomes part of the document’s requirements.
• Presumption of conformity - the legal effect described in Annex ZZ when the standard is cited in the EU Official Journal.

Who uses SIST EN 62841-4-1:2026/kFprAB:2026?

SIST EN 62841-4-1:2020/kFprAB:2026 is used by chain saw manufacturers, design engineers, test laboratories, quality managers, and conformity assessment teams. It is relevant in electric tools, forestry equipment, and lawn and garden machinery, especially where handle geometry, guards, acoustic testing, and EU machinery compliance have to be documented.

What changed in SIST EN 62841-4-1:2020/kFprAB:2026 from the previous edition?

SIST EN 62841-4-1:2020/kFprAB:2026 amends EN 62841-4-1:2020/prA1:2022. The amendment introduces common modifications, and the text states that EN 62841-4-1:2020/A1:2022 already brought clarifications and corrections to several clauses, particularly for moisture resistance of chain saws.

The explicit changes in this draft are:

• a replacement of subclause 19.102.2.1,
• a replacement of Annex ZA,
• a replacement of Annex ZZ.

Which standards are used with SIST EN 62841-4-1:2020/kFprAB:2026?

Annex ZA lists the referenced standards used with this document. They provide the test and measurement methods that support the chain saw safety requirements.

Referenced standards	Contribution
IEC 60664-3	Insulation coordination for coating, potting, or moulding in low-voltage equipment
IEC 61672-1	Sound level meter specifications for acoustic measurements
ISO 37	Tensile stress-strain properties of rubber
ISO 354	Sound absorption measurement in a reverberation room
ISO 6533, ISO 6534, ISO 7914, ISO 7915, ISO 9518, ISO 10726, ISO 13772	Chain saw guard dimensions, mechanical strength, handle clearance, handle strength, kickback test, chain catcher, and chain brake performance

ISO 17080	Design principles for single-panel product safety labels
ISO 22868, ISO 3744	Noise test code and sound power measurement methods

What does the SIST EN 62841-4-1:2020/kFprAB:2026 document contain?

The document contains the amendment text, the revised Clause 19 wording, and replacement annexes ZA and ZZ. It also includes Figure 108, Figure 111, Table 101, and Table ZZ.1, which together show how the handle clearances are measured and how the clauses map to Directive 2006/42/EC.

For readers, the most useful parts are the measurement-based handle rule, the barrier opening limit, the updated reference list, and the EU compliance correspondence table.
