This document replaces GB/T 18029:10-2009 "Wheelchairs - Part 10: Determination of the ability of electric wheelchairs to overcome obstacles", and

Compared with GB/T 18029:10-2009, in addition to structural adjustment and editorial changes, the main technical changes are as follows:

--- Added requirements and test methods for wheelchair vehicles to approach obstacles (see 7:3);

--- Changed the height of the test obstacle, from the original 20mm~200mm to 10mm~200mm, and increased the increase of each level:

The amount is changed from 20mm to 5mm (see 5:2, 5:2 of the:2009 edition);

--- Increase the measurement provisions for the starting distance for obstacle crossing and illustrate with diagrams (see 7:4);

--- Added test methods for wheelchairs equipped with devices intended by the manufacturer to climb obstacles (see 7:8);

--- Added the requirements for releasing test results in accordance with the provisions of GB/T 18029:15 (see Chapter 9):

--- Part 26: Terminology;

--- Part 28: Requirements and test methods for stair climbing appliances;

--- Part 30: Wheelchair test methods and requirements for changing the occupant's posture:

Among them, Part 26 is the term; Part 11, Part 13 stipulates the infrastructure requirements for wheelchair testing; Part 22 stipulates

Sets test preparation requirements; Part 15 sets out information release requirements; Parts 1, 3, 5, 7, 8

Part, Part 10, Part 16 specifies the general requirements and test methods for all wheelchairs (including manual and electric); Part 2,

Part 4, Part 6, Part 9, Part 14, Part 21, Part 25 set out the requirements and

Test methods; Parts 19, 28, and 30 specify requirements for special functional wheelchairs:

When choosing the most suitable wheelchair for the user considering the range and safety of the wheelchair accessible passage, the electric wheelchair climbs

The ability to (up and down) obstacles is a crucial factor:

Wheelchair capacity may be affected by its ability to safely pass obstacles, such as thresholds, changes in the height of the road surface and the edge of the pavement:

Stone etc:

The wheelchair's ability to drive up the height of an obstacle is different from its ability to get off the obstacle: However, how high an obstacle can a wheelchair climb?

Obstacles and how high they can get off are important to users and prescribers: The ability of the wheelchair to climb (up and down) obstacles is also related to

The technique of operating the wheelchair is also related to changing the mode of operation (such as four-wheel drive):

This document specifies a uniform method for determining the ability of electric wheelchairs to climb (up and down) obstacles in order to obtain comparable results:

4 Principles

Tests are used to measure the ability of an electric wheelchair to climb over obstacles such as sidewalk curbs and steps:

5 Testing Facilities

5:1 Test Platform

For hard platforms, the flatness error should be less than 5mm, the horizontal error should be less than +/-0:5°, and the surface friction coefficient should comply with ISO 7176-

13 provisions:

Note: The test platform can accommodate obstacles as specified in 5:2 and there is enough space to place the test wheelchair at a distance of 0:5m from the obstacle:
