With the advancement of time, people’s living standards have improved, and the national system has been improved time and time again. A series of standards have been formulated for people’s lives and work, with the intention of ensuring that people’s rights and interests are not harmed, and also to make a norm for the current market. Recently, Some netizens said that it is inconvenient for the elderly at home, and they want to buy an electric wheelchair for the elderly to facilitate their mobility, but they don’t know the various technologies of electric wheelchairs, and they don’t know how to refer to them when choosing them. After all, they are also bought for the elderly, so they must be bought. Secure, easy-to-use wheelchairs. Let me introduce to you the latest test standards for wheelchairs released by the country, so that you can choose them conveniently.
The current national standard for electric wheelchairs is GB/T13800-92, which specifies the terms, models, safety performance, test methods, inspection rules, etc. of manual wheelchairs. Here we mainly talk about the requirements and test methods of some main performance indicators of wheelchairs that are closely related to consumers in the standard.
1. Wheel grounding
When the user is driving independently, if he accidentally presses on a stone or crosses a small ridge, the other wheels cannot be suspended in the air, causing the direction to lose control, and causing the car to turn suddenly and pose a threat.
Test requirements: place the wheelchair horizontally on the test bench, make a football with a mass of 25 kg of iron sand fall freely on the seat for 3 times from a height of 250 mm, there should be no deformation, breakage, tearing, desoldering and damage and other abnormal phenomena.
2. Static stability
When the user drives independently to climb up (down) a ramp, or drive across a ramp, the wheelchair itself is very light and easy to tilt, but within a certain slope, it cannot “turn over on its back” , “under the pocket head” or overturned sideways.
Test requirements: Place the manual four-wheeled wheelchair equipped with the test dummy and the brake on the test platform with adjustable inclination, first place the electric wheelchair in the direction of pushing up and down the slope, and increase the platform at the same rate Slope, within 10°, the wheels on the uphill position must not leave the test table; then press the wheelchair to the left and right to place at right angles to the slope, and within 15°, the wheels on the uphill position must not leave the test table.
3. Standing slope performance
The wheelchair caregiver pushed the user to the slope and braked the brakes for some reason and left. As a result, the wheelchair slipped down the slope or turned over, which is unpredictable. This indicator is to avoid such situations from happening.
Test requirements: Adjust the brakes of the manual four-wheeled wheelchair equipped with the test dummy properly and tighten it, place it on the test platform with adjustable inclination according to the four directions of forward, backward, left and right, and place the casters in the In the towing position, increase the slope of the platform at a constant rate, and within 8°, there must be no rolling, sliding, or the phenomenon that the wheels leave the test platform.
The above are the three implementation standards for electric wheelchairs in our country and the corresponding test methods. For us consumers, buying a safe, safe and qualified product is the wish of each of us, but for some profiteers and unscrupulous businessmen, they are desperate to seek profits. But with the above methods, everyone must have certain standards and methods when choosing wheelchairs. Especially in some unknown sales outlets, you must test it. If you go to the regular market, you can rest assured, but you might as well try After all, there is no 100% pass. That’s all for today’s introduction, I hope it can help you.
