EN 581-2 Part 2: Mechanical Safety Requirements and Test Methods for Seating

The European standard “EN 581-2 Outdoor furniture - Seating and tables for camping, home and work use - Part 2: Mechanical safety requirements and test methods for seating” describes the minimum requirements for safety, durability and robustness of all types of outdoor seating for adults, regardless of materials, design/construction or manufacturing processes. The following are outside the scope of this standard:

EN 581-2 Part 2: Mechanical Safety Requirements and Test Methods for Seating

  • Street furniture.
  • Removable upholstery and coverings.
  • Requirements regarding the durability of wheels and height adjustment mechanisms.
  • Electrical safety requirements.
  • Resistance requirements against aging and deterioration caused by light, temperature, and humidity.

The test requirements in this standard are based on use by individuals weighing up to 110 kg.

For the purposes of this standard, the following terms and definitions apply:

  • Contractual use outdoor seating: This refers to outdoor seating designed for non-private use in public spaces.
  • Indoor-use outdoor seating: This refers to outdoor seating designed for private use in areas not open to the public.
  • Outdoor seating for camping: This is a lightweight, foldable or detachable outdoor seating arrangement designed for use in camping and travel.
  • Lounge chair: A seating arrangement designed for reclining, featuring at least one backrest position with a theta angle between 0 and 45 degrees, and a legrest that is an integral part of the product and designed to support the user's entire body weight.
  • Street furniture: This refers to outdoor furniture used in public spaces that is permanently fixed to the ground or to a structure (e.g., bus stop, wall) or cannot be removed manually.

Tests are carried out as specified in EN 1728 and EN 1022 standards. Except for seats with a seat and backrest made of a single piece of flexible material (e.g., textile) attached only to the top and bottom edges, the load points of the seat and backrest are determined according to EN 1728. For seats with a seat and backrest made of a single piece of flexible material (e.g., textile) attached only to the top and bottom edges, the load point is the lowest point reached when a cylinder is placed on the seat.

As outdoor spaces continue to become extensions of indoor living, such as backyard barbecues, cafe verandas, and campground gatherings, the demand for durable and safe furniture is also increasing. The EN 581-2 standard builds upon the fundamental safety principles of the EN 581-1 standard by thoroughly examining the mechanical robustness of outdoor chairs, benches, and sun loungers. This standard prioritizes user safety while ensuring that seating areas can withstand the rigors of repeated use, varying loads, and environmental stresses.

The EN 581-2 standard complements the EN 581 series of standards: EN 581-1 for general safety, EN 582-2 for seating mechanics, and EN 582-3 for tables.

The EN 581-2 standard targets adult users up to 110 kg, excluding street furniture, removable flooring, and heavy-duty applications. By standardizing strength, stability, and durability testing, this standard helps manufacturers develop robust products without compromising comfort or safety, reducing the risk of collapse or failure that could lead to injury.

The EN 581-2 standard applies to all types of outdoor seating (folding chairs, recliners, benches) for camping, home and contractual (e.g. accommodation) uses, regardless of materials such as metal, wood or synthetic. It assumes normal adult usage patterns, excluding children's furniture or spectator seating. Environmental degradation (e.g., UV or moisture effects) is excluded and deferred to future complementary standards for weather resistance.

This standard differentiates usage categories to match intensity levels as follows:

  • Household: Light, intermittent home use.
  • Contractual: Mid-level commercial use, such as garden cafes.
  • Camping: Portable, durable applications that withstand transport stress.

This incremental approach balances innovation with practicality, ensuring personalized adaptation.

The EN 581-2 standard mandates strict criteria for mechanical integrity, focusing on preventing failures under load. It excludes electrical safety and wheel durability but emphasizes the following:

  • Strength and load-bearing capacity: Structures must withstand static loads (e.g., 110 kg in seats) without deformation or fracture exceeding 10 mm. Backrests and armrests are subjected to vertical and horizontal forces for tilting or pushing simulation.
  • Durability and fatigue resistance: Cyclic tests simulate repeated sitting/standing movements: 5.000 cycles for home use, 10.000 cycles for contracted use, and 2.500 cycles for camping (including carrying simulations). No component failure or imbalance is allowed after testing.
  • Stability: Forward, lateral and rear tipping tests ensure the seat remains upright under eccentric loads or on inclines of up to 3 degrees. Adjustable features (e.g. reclining seats) must be securely locked.

These requirements are material-independent, promoting sustainable designs such as recycled composites.

Tests under the EN 581-2 standard are methodical and measurable, using specialized equipment to apply forces and cycles precisely. The main methods are as follows:

  • Seat static load
  • Back static load
  • Fatigue test
  • Balance test
  • Drop test (camp)

For many years, our organization, with its competent and experienced staff, has been understanding the needs of its clients, providing the advanced testing services they require, and assisting in the establishment, implementation, and improvement of management systems. Within this framework, we also provide testing services to businesses in accordance with the "EN 581-2 Outdoor furniture - Seating and tables for camping, home and work use - Part 2: Mechanical safety requirements and test methods for seating" standard.
