3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1 rehabilitation training instrument
device for rehabilitation of persons with physical dysfunction
3.2 training position

5.2.9 The resting part or other necessary parts in contact with the human body
during training shall be protected by soft package.
5.2.10 If the weight’s moving weight is not in the user's field of view when
moving, the protective side shield shall be provided on all other sides except
the user side so as to prevent third parties from accidentally entering the training
area.
5.3 Component structure design requirements
5.3.1 Hand grip
5.3.1.1 The ring hand grip material used for carrying shall be 20mm~30mm in
diameter.
5.3.1.2 For rod-shaped hand grip used for carrying, the material diameter shall
be 30 mm to 45 mm in the case of a circle, and the material width shall be 30
mm to 45 mm in the case of a rectangle.
5.3.1.3 If necessary, the handle shall be assembled and suitable for hand grip,
anti-slip, and non-rotation. There shall be no falling off due to improper fitting
and vibration.
5.3.2 Step ladder
5.3.2.1 The ladder of the step shall be smooth and anti-slip. Straight steps
without kick faces (see Figure 4) and with flanges (see Figure 5) shall not be
used. When the flanged step cannot be avoided, the distance from the
protruding kick surface shall be ≤ 5mm.
shall not be less than 5 mm.
5.6.2 The exposed length of the screw shall not exceed 2 times its pitch. The
protruding part does not allow sharp tips and burrs, or the ends shall be covered
with a smooth nut cap.
5.6.3 The edges and sharp corners of hard materials shall be protected by
round transitions or other permanent protections with a radius greater than 2.5
mm.
5.6.4 The end of the hard pipe shall be blocked by components or pipe plugs,
and shall not fall off due to aging, improper cooperation, vibration and mild man-
made damage.
5.6.5 Weld surface of weldment shall be even and flat. There shall be no defects
such as missing welding, virtual welding, welding, slag inclusion, cracks, burn
through, splashes, etc.
5.6.6 The joint of wooden pieces shall be firmly combined. The joint junction is
not more than 0.2 mm. There shall be no collapse or knife marks on the
machined surface. There shall be no burrs or insects on the surface and edges,
and the sharp corners shall be blunt.
5.6.7 The collage of veneer and other materials shall be tight and flat.
Degumming, bubbling, dents, indentations, etc. are not allowed. Parts made of
wood-based panels shall be edged. Edge banding does not allow degumming,
bubbling.
5.7 Soft package requirements
5.7.1 Various soft package fillings such as seat cushions and backrests shall
be full. The seam edge shall be firm and regular. The outer surface shall not
have defects such as wrinkles, fading, jumpers and breakage.

Defects such as exposed bottom, blistering, falling off, cracking, sag and
obvious scratches, bumps, etc. are not allowed.
5.8.3 The surface of the coated parts shall be bright and even. There shall be
no defects such as rust, bottoming, bubbling, flaking and obvious scratches,
are assessed by visual inspection, hand touching, trial, observation, etc. They
shall be tested by 3 people. Take most of the same conclusions as the
assessment results.
6.2.2 Use Vernier calipers, steel tape measures, steel rulers or special gauges
to measure structural dimensions.
6.3 Stability test
6.3.1 Grounding stability test
Place the test instrument on a plate. Use a feeler to measure the distance
