Applicability 
This test applies to all chairs without pedestal bases. 
 
Purpose of Test 
The purpose of this test is to evaluate the ability of legs to withstand horizontal side and frontal forces. 
18.3 Front Load Test 
18.3.1 Test Setup 
The chair shall be placed on a test platform, with the back legs restrained by a block 11 to 38 mm (.44 to 1.50 in.) high. Figure 18a shows one acceptable method of restraining the chair.
 
If adjustable features are available, all adjustments shall be set at normal use conditions. 
The loading device shall be attached to the chair so that an initially horizontal force is applied inward and parallel to the front-to-rear axis of the chair, between 13 mm (0.5 in.) and 38 mm (1.5 in.) from the bottom of a leg as shown in Figure 18a. For chairs with casters, apply the load to the chair leg, but not more than 13 mm (0.5 in.) from the point of caster attachment (bottom of the leg). The load shall be applied to the apparent weakest point of the leg. Where the apparent weakest point is the left or right edge of the leg, apply the load so that it is no greater than 25 mm (1.0 in.) from the edge.
 
18.3.2 Test Procedures
 Functional Load Test 
A force of 334 N (75 lbf.) shall be applied once to each front leg individually for one minute. 
Remove the force. 
Proof Load Test 
A force of 503 N (113 lbf.) shall be applied once to each front leg individually for one minute. 
Remove the force. 

ANSI/BIFMA X5.1-2011 
Side Load Test 
Note: A separate chair may be used for the side load portion of the test. 

18.4.1 Test Setup 
The chair shall be placed on a test platform with the side leg(s) restrained by a block 11 to 38 mm (.44 to 1.50 in.) high. Figure 18b shows one acceptable method of restraining the chair.
 
If adjustable features are available, all adjustments shall be set at normal use conditions. 
The loading device shall be attached to the chair so that an initially horizontal force is applied inward and parallel to the side-to-side axis of the chair, between 13 mm (0.5 in.) and 38 mm (1.5 in.) from the bottom of a leg as shown in Figure 18b. For chairs with casters, apply the load to the chair leg, but not more than 13 mm (0.5 in.) from the point of caster attachment (bottom of the leg). The load shall be applied to the apparent weakest point (front-to-back) of the leg. Where the apparent weakest point is the front or rear edge of the leg, apply the load so that it is no greater than 25 mm (1.0 in.) from the edge.
 
18.4.2 Test Procedure 
 Functional Load Test 
A force of 334 N (75 lbf.) shall be applied once to a front and rear leg individually for one (1) minute.
Remove the force. 
Proof Load Test 
A force of 503 N (113 lbf.) shall be applied once to a front and rear leg individually for one (1) minute. 
Remove the force.
