DPS has published the SSH EN 1022:2023 standard "Furniture - Seating - Determination of durability"

The EN 1022:2023 standard specifies test methods and requirements for determining the stability of all types of seats for adults, weighing up to 110 kg, regardless of use, materials, design/construction or manufacturing process. The test methods described can be used for seats for children and adults of heavier weight, by modifying the test loads and load points. This document does not apply to children's chairs, table-mounted chairs and toilet seats, which are covered by other European standards. This standard contains two annexes: Annex A (normative) - Data on the load surface of the seats, Annex B (normative) - Test parameters.
