`

`
`Scope
`
`1
`
`This testing procedure is intended to thoroughly test the Trey Project chair in order
`to verify that it will be able to withstand all reasonable abuse that it could be dealt
`during its lifetime. Abuse beyond that which is expected in the intended market is not
`necessarily taken into account or tested for.
`
`Testing Process for Trey Assembly
`
` 2
`
`
`
`
`When assembled, the Trey chair is classified as a Type I tilting chair, as defined in
`ANSI/BIFMA X5.1-2002. In some of the tests, the extent of the testing is increased
`to push towards the point of failure. Any necessary test modifications will be listed
`where applicable. Term definitions follow the convention used in ANSI/BIFMA X5.1-
`2002.
`
`(static)
`2.1 Backrest Strength Test
`The purpose of this test is to evaluate the ability of the chair to withstand stresses
`such as those caused by the user exerting a rearward force on the backrest of the
`chair.
`
`The testing procedure will follow the ANSI/BIFMA X5.1-2002 standards outlined in
`Section 5 (p. 18). There will be a variation in the extent of the testing. After the proof
`load test is performed (Section 5.4.2), the load force will be increased until a sudden
`or major change in the structural integrity of the chair occurs.
`
`(dynamic)
`
`2.2 Drop Test
`The purpose of this test is to evaluate the ability of the chair to withstand heavy and
`abusive impact forces on the seat.
`
`
`
`

`
`Sauder Exhibit 2051
`JSquared Inc. v Sauder Manufacturing Co.
`IPR2015-00774
`
`

`
`The testing procedure will follow the ANSI/BIFMA X5.1-2002 standards outlined in
`Section 8 (pp. 29 – 31). There will be a variation in the extent of the testing. After the
`functional load (Section 8.4.1) and proof load (Section 8.4.2) tests are performed,
`the drop height of the test bag – using the proof load weight – will be increased by 3
`in. increments until either the height reaches 305 mm (12 in.) or a sudden or major
`change in the structural integrity of the chair occurs, whichever comes first.
`
`(cyclic)
`2.3 Swivel Test
`The purpose of this test is to evaluate the ability of the chair to withstand stresses
`and wear of repeated swiveling.
`
`The testing procedure will follow the ANSI/BIFMA X5.1-2002 standards outlined in
`Section 9 (p. 33).
`
`(cyclic)
`
`Tilt Mechanism Test
`2.4
`The purpose of this test is to evaluate the ability of the tilt mechanism to withstand
`fatigue stresses and wear caused by repeated tilting.
`
`The testing procedure will follow the ANSI/BIFMA X5.1-2002 standards outlined in
`Section 10 (p. 35).
`
`(cyclic)
`2.5 Seating Durability Tests
`The purpose of these tests is to evaluate the ability of the chair to withstand fatigue
`stresses and wear caused by downward vertical force(s) on the seat.
`
`The testing procedure will follow the ANSI/BIFMA X5.1-2002 standards outlined in
`Section 11 (pp. 37 – 39).
`
`2.6 Stability Tests
`The purpose of these tests is to evaluate the front and rear stability of the chair.

`
`

`
`The testing procedure will follow the ANSI/BIFMA X5.1-2002 standards outlined in
`Section 12 (pp. 41 – 45). This test is to be performed on only a chair with casters.
`
`(cyclic)
`2.7 Backrest Durability Test
`The purpose of this test is to evaluate the ability of the chair to withstand fatigue
`stresses and wear caused by a rearward force on the backrest of the chair.
`
`The testing procedure will follow the ANSI/BIFMA X5.1-2002 standards outlined in
`Section 15 (pp. 53 – 57).
`
`(cyclic)
`
`2.8 Caster/Chair Base Durability Test
`The purpose of this test is to evaluate the ability of the chair base and casters to
`withstand fatigue stresses and wear caused by moving the chair back and forth.
`
`The testing procedure will follow the ANSI/BIFMA X5.1-2002 standards outlined in
`Section 17 (p. 67).
`
`(dynamic)
`
`2.9 Chair Glide Strength Test
`The purpose of this test is to evaluate the ability of the chair glides to withstand
`impact forces such as those experienced upon contact with a fixed object while the
`chair is being slid across the floor.
`2.9.1 Test Procedure
`This test is to be performed only on a chair with glides. The chair will be
`attached to a machine such as that used in Section 2.8. If the seat portion of
`the chair is not attached to the base, then weights equivalent to the weight of
`the seat portion will be put on the base.
`
`The base is to be run over an obstacle such as those used in Section 2.8 at a
`speed of 1.0 m/s (3.3 ft/s) over a long enough distance that at least one of the
`glides contacts the obstacle. There should be no loss of serviceability.

`
`2.10 Latch Durability Test
`The purpose of this test is to evaluate the ability of the chair latch to withstand
`fatigue stresses and wear caused by the repeated use of the pedestal latch.
`2.10.1 Test Procedure
`The chair or chair base will be fixed in the manner shown in ANSI/BIFMA
`X5.1-2002 Figure 5e (p. 17). Some mechanism will depress the latch,
`followed by the removal of the seat from the latch end of the pedestal table.
`Next, the latch will be released, and the seat will be pushed back onto the
`pedestal until the latch has fully engaged.
`
`
`The procedure is to be repeated for 10,000 cycles at the rate of 5 to 10 cycles per
`minute.
`
`There will be no loss of serviceability.
`
`(dynamic)
`
`2.11 Latch Impact Tests
`The purpose of these tests is to evaluate the ability of the chair to withstand impact
`forces in a direction that puts stress on the latch structure.
`
`2.11.1 Test Procedure
`The chair shall be fastened as in ANSI/BIFMA X5.1-2002 Figure 5e (p. 17).
`
` A
`
` sandbag will be swung in to strike the seat portion of the chair directly from
`the side. Repeat the procedure, rotating the chair so as to strike the front
`edge of the seat and the center of the back of the chair frame as well.
`
`The sandbag will be released a straight-line distance of 305 mm (12 in.) from
`the edge of the chair, and will be positioned in such a way that the pivot point
`is 610 mm (24 in.) directly above the edge of the chair being struck. The
`sandbag will weigh 23 kg (50 lb.). There will be no loss of serviceability.

`
`2.12 Latch Strength Test
`The purpose of these tests is to evaluate the ability of the latch to withstand static
`forces in a direction that puts stress on the latch structure.
`2.12.1 Test Procedure
`The chair is to be laid on its side on the testing surface, with the height
`adjustment cylinder extended fully.
`
` A
`
` load will be placed on the spindle of the base at a distance of 150 mm (6
`in.) from the bottom of the table that latches into the chair. It will remain there
`for 1 minute before removal.
`2.12.2 Functional Load
`The weight will have a magnitude of 102 kg (225 lb.). There will be no loss of
`serviceability.
`2.12.3 Proof Load
`The weight will have a magnitude of 136 kg (300 lb.). There will be no sudden
`or major change in the structural integrity of the chair.
`
`
`(dynamic)
`
`2.13 Random Impact Test
`The purpose of this test is to evaluate the ability of the chair to withstand impacts
`such as those experienced when the chair collides with fixed surfaces.
`2.13.1 Test Procedure
`The chair is to be dropped and allowed to freefall to the testing surface. This
`is to be repeated several times, each time dropping in such a way that it lands
`on different parts of the chair. High levels of approximation are acceptable in
`the height measurements.
`2.13.2 Functional Load
`In the functional load test, the chair shall be dropped from a height of
`approximately 0.9 m (3 ft.), as measured to the approximated center of mass
`of the chair. There will be no loss of serviceability.

`
`The proof load height is 1.5 m (5 ft.), as measured to the approximated center
`of mass of the chair. There will be no sudden or major change in the
`structural integrity of the chair. Loss of serviceability is acceptable.
`
`
`2.14 Flammability Test
`The purpose of this test is to evaluate the compliance of the chair with
`flammability standards.
`
`The test will follow the procedure outlined in Technical Bulletin 133 released
`by the State of California Department of Consumer Affairs Bureau of Home
`Furnishings and Thermal Insulation.
`
`Testing Process for Seat Component
`
` 3
`
`
`

`classification. Some of the tests are repeated from Section 2 due to the presence of
`different weight-bearing structures.
`
`
`3.1 Drop Test
`Repeat Section 2.2.
`
`3.2 Seating Durability Test
`Repeat Section 2.5.
`
`3.3 Random Impact Test

`The chair seat is to be placed on its side on the testing surface, fixed in such
`a way that it cannot tip over.
`
` A
`
` sandbag such as that used in Section 2.2 will be placed on the edge of the
`seat bottom, centered front to back, with some weight on the seat cushion
`and some on the runner. It will remain there for 1 minute before removal.
