3 Terms and Definitions
For the purposes of this document, the following terms and definitions apply.
3.1
axillary crutch
A hand-held device that provides support and balance during walking.
NOTE: Consists of an axillary support, a handgrip, uprights, and one or more tips, see Figure 1.

3.2
axillary support
The support element placed under the armpit area, against the upper body during use.
3.3
axillary support cover
A component covering the axillary support.
3.4
handgrip
The component grasped by the hand during use.
3.5
handgrip cover
A component covering the handgrip.
3.6
side bows
Components connecting the axillary support, handgrip, and the footpiece/extension bar(s).
3.7
footpiece/extension bar
Adjustable components connected to the lower end of the side bows.
3.8
tip
The component that contacts the ground and bears the load during use. Also known as ferrule.
3.9
maximum user mass
The maximum permissible mass of the user.
4 Requirements
4.1 Appearance
4.1.1 Accessible surfaces shall be free from burrs, sharp corners, sharp edges, and other defects that could cause injury to the user or damage to clothing.
4.1.2 The surface of coatings (platings) shall have uniform color, be smooth and even, and shall be free from defects such as bare substrate, blistering, peeling, cracking, runs, wrinkles, and obvious scratches or impact marks.
4.1.3 The oxide film on aluminum parts shall be free from obvious defects such as scratches, burn marks, corrosion, stains, and rack marks.
4.1.4 The surface of plastic parts shall be smooth, with uniform color, and free from defects such as flash, dents, cracks, and obvious scratches.
4.1.5 Wood shall be free from defects such as rot, insect damage, knots, splits, ring shakes, and textured dents.
4.1.6 The surface of carbon fiber components shall be smooth, with uniform color, and free from frayed edges and burrs.
4.2 Assembly
4.2.1 All components of the axillary crutch shall be fully assembled, accurately aligned, and securely fixed. No abnormal noise shall be produced during normal use.
4.2.2 The height of the crutch and the relative position of the handgrip shall be adjustable by hand. Devices intended for hand adjustment shall be easy to operate and shall remain securely fixed during normal use.
4.2.3 Height adjustment spring pins shall be installed on both sides, and the protruding height shall be greater than 3 mm.
4.3 Axillary Support (Cover) and Handgrip (Cover)
4.3.1 The axillary support cover and handgrip cover shall be resilient, non-absorbent, colorfast, and have anti-slip properties.
4.3.2 The handgrip and handgrip cover shall not rotate or slip relative to each other during use.
4.3.3 The axillary support and axillary support cover shall not slip or detach relative to each other during use.
4.3.4 The axillary support cover and handgrip cover shall be easy to clean.
4.4 Tips
4.4.1 The tip material shall be of appropriate hardness and shall not stick or adhere to the ground surface during use.
4.4.2 The tip shall fit tightly with the footpiece/extension bar. A washer shall be installed between the tip and the footpiece/extension bar. The tip shall be replaceable.
4.4.3 The diameter of the tip base shall not be less than 35 mm.
4.4.4 The thickness of the tip base (excluding grooves or protrusions) shall be greater than 10 mm.
4.4.5 The insertion depth of the footpiece/extension bar into the tip socket shall be greater than half of the tip's height.
4.4.6 The friction of the tip shall comply with the requirements of GB/T 40889.1. The minimum friction force measured according to the specified test method shall not be less than 25 N.
4.5 Mechanical Strength
4.5.1 After the static load strength test according to 6.5.1, no component shall show cracks, fracture, or permanent deformation.
4.5.2 After the bending strength test according to 6.5.2, the deflection at the midpoint of the axillary crutch shall not exceed 50 mm.
4.5.3 After the impact strength test according to 6.5.3, no component shall show cracks, fracture, or permanent deformation.
4.5.4 After the weight swing test according to 6.5.4, no component shall show loosening, cracks, fracture, or permanent deformation.
4.5.5 After the axillary support security test according to 6.5.5, no component shall show loosening, cracks, fracture, or permanent deformation.
4.5.6 After the fatigue strength test according to 6.5.6, no component shall show cracks, fracture, or permanent deformation.
