Technical Parameters

Test Standards

ANSI/BIFMA X5.1-2017 11.4; BS EN 1335-3:2009 7.1.1, 7.1.2; BS EN 1022 7.3; UL 4041 E2-2019 33.1.4, 33.1.5; GB/T 10257.2-2013 4.1; QB/T 2280-2016 6.6.1;

TEST PROCEDURES:

a) Apply a vertical load of 61 kg (135 lb.), through the front-stability loading disk (See Figure 11e), so that the center if the disk portion is 60 mm (2.4 in.) from the front center edge of the load-bearing surface of the seat. Note: It is recommended that the fixture/method shown in Appendix D be used to assist in locating the 60 mm (2.4 in.)

loading dimension. If using the fixture, the vertical height of the fixture should allow contact at the approximate center of the sloped face of the fixture with the tangent (touch point) on the front of the seat.

b) Apply a horizontal force of 20 N (4.5 lbf.) at the same height that the vertical force is applied (at the point of contact of the loading fixture). The force shall be coincident (in-line) with the side-to-side center line of the seat.
