How to test the projectile toys? What is projectile toys? Please refer to the following. If the toys you produce meet one of requirement, it is projectile toy. 

a) The requirements of (projectile toys with stored energy) do not apply to projectiles where the maximum range ofthe discharged projectile is 300 mm or less when measured in accordance with determination of projectile range.
b) The requirement does not apply to projectile toys for children 3 years and over with a
range of100 mm or less when measured in accordance with determination of projectile range.
c) The requirements of (projectile toys without stored energy) do not apply to:
components that function as projectiles which are permanently enclosed within a toy unless
they are liberated when the outer container is tested according to reasonably foreseeable
abuse tests;ground based toys propelled along a track 01' launched onto another surface.

You can use Kinetic Energy Tester to test the projectile toys and used to test related materials from the launch of the toys and toys from the launch of a non-exclusive material that may be caused by the ejection of some, but not all of the potential risk of accidents.

To determine the size catapults kinetic energy of toys, the ejection of parts of the test apparatus through the tube or external testing of the components of the two sensors detect the ejection toy parts used away after a certain period of time, it has calculated the move Energy. The main instruments used for this test launch of baby toys or children's safety.

What are the product parameters of  kinetic energy tester?

What is the Kinetic Energy's Tester test process?
1.1 Connect the power supply. The display shows 0.000000
1.2 Select whether to use an external sensor or an internal sensor depending on the sample to be tested. If the external sensor is selected, the selector switch is turned to the ext file. If the sensor in the cartridge is selected, the file is switched to the int file.
1.3 Using Internal Sensors
1.4 Using an external sensor
