Children are the most concerned about and care for the whole society, children's favorite toys generally market developing rapidly, at the same time all kinds of toys to children due to a quality problem hurt also happen from time to tome, so countries all over the world for their own the toys on the market are becoming more strict. Many countries have established their own safety regulations, these products must ensure that its products comply with relevant standards before sales in the region.

Manufacturers have to due to manufacturing defects, poor design or the use of inappropriate materials due to the accident. The launch of toys EN71 certification laws in Europe, its significance is through the EN71 standard for toys products for Europe market for technical specification, so as to reduce or avoid the harm of children's toys. Tested to EN71 standard for toys products, the most commonly used method of torsion, tension test, drop test, impact test and pressure test.

A, torsion - tension tests (Torque&tension Test)

Torsion testing instrument required: a stopwatch, torque meter, torque wrench (2 kinds, depending on the model selects the suitable tools)

Testing procedures:

Parts within 5 seconds on ShiJiaShun clockwise torsion, torsion or 0.34 N - m to 180 degrees, maintain 10 seconds, then relax the parts back to the state. Counterclockwise repeat the above process. If parts of the most prominent size less than or equal to 6 mm, the force applied 50 n + 2 n; If parts of the most prominent size greater than 6 mm, exerting force 90 n + 2 n. 5 seconds on the pounds, maintain 10 seconds.

Toy criterion: designed for children too young to independent sitting up toys can't fissures and cracks. If crack obviously can't hurt, it is acceptable. Toys for children under the age of 3 do not produce the widget, accessible sharp point and sharp edges. Mask and helmet cannot have exposed sharp point, sharp edges, or loose materials can enter the eyes. Mouth moving toys toys and water valve does not produce the widget.

Second, the Drop Test (Drop Test)

Apparatus: EN floor

The direction of the toy to the most rigorous testing procedures: from EN to floor 85 cm + 5 cm high drop 5 times.

Toy criterion: designed for children too young to independent sitting up toy outside surface fissures and cracks. If crack obviously can't hurt, it is acceptable. For children under 3 years to play the toy does not produce the widget, contact with sharp points or sharp edges. Mask and helmet cannot have exposed sharp point, sharp edges, or loose materials can enter the eyes. Will contact the driving mechanism of not damaging.

Three, impact Test (mpact Test)

Apparatus: a diameter of 80 mm + 2 mm, weight 1 kg + 0.02 kg of steel weight

Test steps: place the toy in the most vulnerable position in a horizontal steel plane, with the weights from 100 mm to + 2 mm high free fall at the toy at a time.

Toy criterion: designed for children too young to independent sitting up toy outside surface fissures and cracks. If crack obviously can't hurt, it is acceptable. For children under 3 years to play the toy does not produce the widget, contact with sharp points or sharp edges. Mask and helmet cannot have exposed sharp point, sharp edges, or loose materials can enter the eyes. Will contact the driving mechanism of not damaging.

Four, pressure tests (Compression will Test)

Test steps: place the toy on the level of rigid plane, and make the toys tested parts in above. Through a diameter of 30 mm + 1.5 mm rigid metal pressure head to the measured area 110 n + n pressure, 5 seconds on the pounds, maintain 10 seconds.

Instrument image criterion: designed for children too young to independent sitting up toy outside surface fissures and cracks. If crack obviously can't hurt, it is acceptable. For children under 3 years to play the toy does not produce the widget, contact with sharp points or sharp edges. Mask and helmet cannot have exposed sharp point, sharp edges, or loose materials can enter the eyes.
