The following terms and definitions apply to this document.
3.1
Lead aperture
The diameter of the pencil which is inserted into the tapered hole shall not be
less than 8.0 mm.
5.6 Corrosion resistance
As for the pencil sharpener blade having metallic coating is subjected to
corrosion resistance test, the blade corrosion ratio shall be less than 15%.
5.7 Appearance
The blade seat or shell of the pencil sharpener shall be smooth, flat, and free
from defect, crack, or obvious flaw. The blade of the pencil sharpener shall be
free from rust spot, obvious pitting, or metal grinding marks.
5.8 Safety of use
5.8.1 If the pencil sharpener has functional sharp edge and a sharp tip due to
the functionality, it shall provide a cautionary statement, BUT it is not allowed to
have other non-functional sharp edge or sharp tip.
5.8.2 As for the metal edge which is contactable by the pencil sharpener,
including holes and grooves, it shall not contain hazardous burr or oblique thin
edge; BUT such burrs or edges may be folded, curled or formed curling, OR
otherwise they can be protected by permanent protection pieces or coatings.
5.8.3 The end reachable by the exposed screw shall not have exposed sharp
edge or burr, AND its end shall be covered by smooth nuts to make sure that
the sharp edge and burr are not reachable.
6 Test method
This test uses the high-grade wood holder graphite pencil having a hardness of
HB as specified in QB/T 2774-2006.
6.1 Determination of sharpening capacity
USE the pencil sharpener sharpening capacity tester, as shown in Figure 7.
a) FIX the pencil sharpener under test in the fixture, so that it coincides with
the sharpening central axis;
b) INSTALL the pencil on the shaft fixture; INCREASE the feed force to 10
N;
c) START the tester at the speed of not more than 60 r/min; AND after
continuously sharpening 6 pencils, the wood shavings shall be
