Annex A (normative) - Loads, masses and cycles
        for safety tests

This part of EN 1335 specifies the mechanical safety requirements for office work chairs.The requirements are based upon use for 8 h a day by persons weighing up to 110 kg. For more severe conditions of use, increased requirements will be necessary.Annex A (normative) includes loads, masses and cycles for safety tests.Additional loads, masses and cycles for functional tests can be found in EN 1335-3:2009, Annex C.
