Safety Sharp Edge Tester Toys Testing Equipment Laboratory ASTM
F963 EN-71
Product information:
The purpose of this consumer safety specification is to establish
internationally recognized safety requirements for toys. Although
this specification will not eliminate the need for the exercise of
parental responsibility in selecting toys appropriate to the age of
a child, or parental supervision in situations in which children of
various ages many have access to the same toys, its application
will minimize accidents in the normal, intended use and reasonably
foreseeable abuse of the toys covered by the specification.
Because of this, our company has produced one series of testing
products to verify if the toys meet the safety standards.
The feature:
An accessible edge that presents an unreasonable risk of injury
during normal use or reasonably foreseeable abuse. Edges on toys
intended for children under the age of eight years are potentially
hazardous if they fail the sharp edge test.
Technical Parameters:
| Mandrel material | steel |
| Mandrel diameter | 9.53 ± 0.12 mm |
| Apply force | 6 N |
| Mandrel hardness | great than 40 (Rockwell “C” scale) |
| Test | sharp edge test |
| Standard | EN71-1 Clause 8.11 |
Testing principle
Please refer also to the general assembly drawing to assist with
the operation of the instrument.
1.2.1 The instrument is powered by an internal rechargeable battery
pack. When the battery pack can no longer the power necessary to
rotate the mandrel, under load, once at a constant tangential
velocity the top right hand LED will illuminate when a test button
or foot switch is depressed and the instrument will not function
untill it is recharged.
1.2.2 To recharge the battery pack, plug the charging unit into a
suitable 110V single phase electrical supply point and the jack
plug into the male socket at the rear of the instrument case above
the switch connection socket.
1.2.3 The instrument can be used in three basic modes.
Bench Mounted
To operate in this model, fix the base plate supplied firmly to the
front of a suitable work top. Secure the instrument to the base
plate with the two spring catched. For bencj ,ounted use it is most
convenient to operate the unit with the foot switch.
Connect the foot switch to the instrument by plugging it into the socket at the rear of the
instrument case.
Toys can be brought to the unit and applied to it by manipulating
the toy with both hands.
Two Handed Use
For portable two handed use, remove the instrument from the base
plate. Holding the instrument case in both hands, at t he front,
the mandrel can be applied to a toy and operated by means of the
test button on the front right hand side.
Single Handed Use
The instrument is held by the pistol grip in one hand, the mandrel
is applied to the toy and operated using button insert into the end
of the pistol grip handle.
2. Polytetrafluoroethylene (PTFE) tape
PTFE simulates children’s skin, which can represent a child to
access the sharp edge. The tape shall be pressure-sensitive
polytetrafluoroethylene (PTFE) high temperature electrical
insulation tape.
