Description

Chair pull-back test machine KS-OTS-B08

Equipment Introduction: This test instrument is mainly aimed at the office chair back and armrest strength test, this test instrument can be done on the back

Department durability test, can also do arm strength and foot strength test, can do a multi-purpose effect.

Two. The main parameters

1. Load Weight: 109KG (set)

2. Test speed: Durability test 5 to 20 times/min

3. Test force value: Durability test 350N-1500N

4. Display: Touch screen display

5. Control mode :P LC control

6. Number of tests: 1-999999 times (set at will)

7.Power supply:AC /220V、3A、50HZ

8. Air pressure: ≥ 6kg/cm2

9. Full machine power: 0.2KW

10. Machine size: LxWxH s 2450x2800x2180 mm

11. The whole machine has an abnormal alarm

12, cylinder loading module can move left and right, easy to install different station tests.

13. The cylinder is increased, the fixture is ordered is lengthened, and the whole machine mechanism is strengthened for handling.

Three. Introduction to standards and features:

NSI/BIFMA X5.1-2017 5 Backrest Strength Test-Static-TypeIand II class I and Class II chair back strength test - static;

1) Loading device: the northern loading device that meets the standard material size requirements, the back height and loading point of the chair are determined by cmD and back loading template;

2) Load 667N (150lbf) to the backrest in a 70-degree ±10-degree (angle with the back plane, determined by CMD on the north plane), for a further (1) minute, and then 1001 N (225 lbf) for 70 degrees ± 10 degrees. ) force, lasting (1) minutes;

ANSI/BIFMA X5.1-2017 6 Backrest Strength Test-Static-Type III (See Figures 6a by 6d) Class III Chair Back strength Test - Static;

1) Loading device: a northern loading device that meets the requirements of standard material size, the height and loading point of the back of the chair are determined by cmD and back load template;

2) Load 667N (150lbf) to the backrest in a 90-degree ±10-degree (angle with back plane, back plane determined by CMD), continue for 1 minute, and load 1001 N (225 lbf) to the backrest at 70 degrees ± 10 degrees. ) force, lasting (1) minutes;

ANSI/BIFMA X5.1-2017 9 Tilt Mechanism Test-Cyclic Tilt Mechanism Test-Cycle;

1) Loading device: back circulation device that meets standard material size requirements, chair back height and loading point determined by CMD and back loading template;

2) Seat static load 109kg (240lbs)

3) pull or both push the back, at a speed of 10-30 times / minute so that the tilt mechanism in the front and rear gear block ask back and forth movement (will not overwhelm or hit the block) 300,000 times (the best way here is to position the shift The cylinder is not precisely adjusted due to structural limitations and displacement, electric pushback or electric pullback is recommended here;

ANSI/BIFMA X5.1-2017 14 Backrest Durability-Cyclic-Type I chair back-to-back durability test-cycle;

1) Loading device: a back loading device that meets the requirements of standard material size, and the height and loading point of the back of the chair are determined by the CMD and the back loading template;

2) Seat static load 109kg (240lbs)

3) at an initial angle of 90 degrees±10 degrees (with the back plane angle, back plane determined by CMD) direction to load 445N (100lbf) towards the back, loading 120000 times at a speed of 10-30 times / min (back width greater than 406 mm, intermediate 80000 20,000 on the left, 20,000 on the right);ANSI/BIFMA X5.1-2017 15 Backrest Durability-Cyclic-TypeIIand III and Class III chair back-to-back durability test-cycle;

1.1) Loading device: back loader that meets standard material size requirements, chair back height and loading point determined by CMD and back loading template;

2) Seat static load 109kg (240lbs)

3) loads 334N (334N) to the backrest at an initial angle of 90 degrees ±10 degrees (angle with back plane angle, back plane determined by CMD) 75LBF) force, loaded 120,000 times at a speed of 10-30 times per minute (when the back width is greater than 406 mm, 80,000 times in the middle and 20,000 times on the left and 20,000 times on the right).
