LT-JJ03-C1 Outdoor Chair Seat Surface Disposable and Repeated Impact Testing Machine
Compliant with standards
Meets the relevant requirements of BIFMA X5.1-2017, EN 1335:2000, QB/T 2602-2013 and other standards.
technical parameter
1. Maximum impact height: 220mm
2. Impact frequency: 5-15 times/minute
3. Sample limitations: maximum less than 1000mm, maximum width less than 1200mm
4. Maximum impact weight: 300 pounds
5. Power supply (power): 220VAC/5A, 50Hz
6. Gas source: Air pressure: ≥ 0.5MPa; Flow rate: ≥ 800L/min; The gas source is treated with filtered water and dried
7. Main dimensions: length 2300 * width 1550 * height 2800mm
8. Control system:
① A separate industrial control box with breakpoint detection and shutdown function;
② Six digit LCD number with stop/power memory function;
③ Electric height adjustment transmission system;
④ Action control mechanism: The electromagnet is energized and engaged at a low position, the cylinder drives it to rise, and the high position loses power and is released;
⑤ Hydraulic buffering reduces noise
Product Features
1. Can achieve two functions: repeated impact on the seat surface and one-time impact on the seat surface;
2. Adopting an aluminum profile frame structure, the structure is beautiful and elegant;
3. By using an electromagnet to attract and release, the free fall state is fully simulated, with no resistance and low noise during the fall process;
4. The chair adopts a “foot cup” structure to maintain its position horizontally, so that the chair is not constrained by external forces in the vertical direction;
5. Easy to operate, no need for any specialized tools to assist; Equipped with power-off memory function;
6. Different control forms can be selected.
test method
A. Seat reciprocating impact durability test
1. Fix the chair appropriately on a platform to ensure that the impact position does not change during the test. If there are wheels, rotate them to the most easily damaged position.
If there are adjustable components, adjust all adjustable components to their normal usage state.
3. If the cushion material thickness of the seat surface is less than 44mm, thicken the foam plastic to (50 ± 6) mm, and the indentation performance of any foam plastic used for thickening shall not be less than 25% when loaded with (200 ± 22) N.
4. The impact bag has a diameter of about 400mm and a weight of 57kg. It is connected to a circulation device so that it can fall freely. The impact height is 25mm (from the uncompressed surface of the chair), and the impact position is at the center of the chair. The frequency is 10 times/min to 30 times/min, 100000 times. Equivalent methods can be used for testing.
5. The distance between the impact bag and the backrest should not exceed 13mm, and the impact bag should not come into contact with the backrest during the falling process.
B. One time impact durability test for chair seat
1. Testing method: Use 225LBS and 300LBS to punch the chair, once at the high and low points, and observe the damage.
2. Use six wheels with two directional wheels in the middle, four universal wheels in the front and back, and install the two wheels in the middle horizontally below.
3. Functional test: Impact bag with an impact height of 152mm and an impact mass of 102kg, once.
If the seat surface is adjustable, adjust it to the highest and lowest positions and impact once each.
4. Overload test: impact bag with an impact height of 152mm and an impact mass of 136kg, once.
If the seat surface is adjustable, adjust it to the highest and lowest positions and impact once each.
