EN Standard office chair and stool stability testing machine |
1. Head: center load, corner load, side load, stability test
|
 |
2. Seat surface static load: 600N(standard weight), 200mm. |
3. Material: steel
|
4. Machine weight: 390kg
|
5. Forward and lateral tilting force shall not be less than 20N, and backward tilting force shall not be less than 100N
|
- Loading pad: the loading pad is a rigid cylinder with a diameter of 100mm and surface light
Slide, edge fillet radius is 12mm, weight of loading pad should be calculated when loading
Into account. |
| 7. Test allowable error: the allowable error of loading point positioning size is ±2mm, and the allowable error of loading force is ±5%. |
8. Loading method: weights (10KG and 5KG).
|
9. Horizontal loading: weights (20N and 80N).
|
| 10. Lifting method: the cylinder is lifted and the weight is lowered for loading. |
| 11. Air system pressure: 0.3-0.8mpa |
| 12. External dimensions: length 1500* width 1500* height 1600 |
| 13. Control system: none (weight is manually loaded) |

| The product description |
15. Functions: |
| This machine is of desk and chair kind of furniture is plus static load conditions, to determine the stability of the in and under the action of static load without mechanical performance test, the ability of tilting and furniture furniture is simulated in the normal use habit and misuse, each part is a one-off, or repetitive loading condition of strength or ability test. It is used to test the strength of the product under heavy load conditions that may be encountered. |
(1) prestability: |
| 1) place a block at the front foot of the chair |
- At a point 60mm from the front end (most likely to cause a flip), a force of 600N is applied vertically through a loading block with a diameter of 200mm.
|
| 3) along the horizontal line extending outward from the stress point, apply a force of 20N horizontally for 5 seconds |
| Conform to the standard |
4) note: if it is the forward stability test of the chair with rest plate: vertical force and horizontal force are applied to the rest plate |
| Meet BS EN 1335, QBT 2280-2016 chair and stool stability performance test requirements. |
5) requirements: do not tip over |
| (2) lateral stability (all seats without armrests) |
1) place a block on both legs at one end of the chair
|
2) pass through a diameter of 200mm at a point 60mm from the side of the chair (near the end of the block) (most likely to cause a flip)
Of the loading block, applying a force of 600N vertically.
|
3) along the horizontal line extending from the stress point to the side, apply a force of 20N horizontally for 5 seconds
