This standard specifies safety performance requirements, test methods, inspection rules clear umbrella.
This standard applies to textile umbrella, plastic umbrella and umbrella stand made ​​of different materials and reduced bone straight umbrella fold.
2 normative references
The following documents contain provisions which, through reference in this standard has become the standard terms. For dated references, subsequent amendments (excluding corrections) or revisions do not apply to this standard, however, encouraged to whether the latest versions of these documents in accordance with the parties to reach an agreement on this standard . For undated reference documents, the latest versions apply to this standard.
Evaluation of gb/t 18830-2002 anti UV properties of textiles
3 safety performance requirements
3.1 umbrella hat (umbrella top cover) Dimensions
3.1.1 umbrella hat (umbrella top cover) top the minimum size (diameter or length) of not less than 9mm, height of not more than 80mm.
3.1.2 Children umbrella hat (umbrella top sets) must be spherical shape or a circular arc, the top diameter of not less than 15 mm.
3.2 umbrella bead head
3.2.1 umbrella bead head end surface must be spherical or circular shape, diameter not less than 3mm, child umbrella umbrella bead head diameter of not less than 5 mm
3.2.2 open the umbrella, umbrella bead head shall fall by themselves.
3.3 switch performance
After the manual umbrella parachute, leaf springs and leaf springs link should play the role orientation, self parachute should shut umbrella, reliable, does not allow uncontrolled; deformation of the parts may not appear to affect the normal use or damage.
3.4 the use of safety requirements
In the process of using umbrella accessible parts are not allowed to have sharp angle, harm the body's sharp edge.
3.5 umbrella poles, umbrellas fastness
Umbrella pole, combined with umbrellas should be able to withstand the static pull 150n does not shift.
3.6 The performance of anti UV umbrella surface
Identified as with anti ultraviolet function of products, the umbrella surface anti ultraviolet capacity must meet the UPF > 30 and t (UVA) AV < 5%.

4 test methods
4.1 Umbrella hat (umbrella top cover) Dimensions
The top of the minimum size (diameter or length) vernier caliper with an accuracy of a direct measurement of 0.02mm were measured three times at different locations, the measurement results of said minimum value.
Height with an accuracy of 0.02mm depth vernier caliper measured directly, the umbrella is opened, measuring umbrella hat (umbrella top cover) the distance to the top of the umbrella, and were measured three times at different locations to measure the results of the maximum indicated.


4.2 Umbrella bead head
Diameter with an accuracy of 0.02mm vernier caliper measured directly, either take five umbrella bead head measurements to represent the minimum measurement results.
4.2.1 Diameter with an accuracy of 0.02mm vernier caliper measured directly, either take five umbrella bead head measurements to represent the minimum measurement results.
4.2.2 Switch umbrella 10 consecutive times, check whether the umbrella bead head off
4.3 Switching performance
Holding umbrellas rotate back and forth three times, five times and then switch umbrella
Holding umbrellas rotate back and forth three times, five times and then switch umbrella
4.4 Use safety requirements
4.4.1 The sharp angle measuring instrument measuring acute alignment holes being tested to check whether the tip is inserted acute measuring instrument reaches a predetermined depth. Measured tip insertion depth determines the sharpness. If you have access to the recessed tip cap 0.38mm ± 0.02mm measuring the sensor head, and can overcome the spring force of 2.5 n, so that the sensor head moves 0.12mm ± 0.02mm, acute meter lights, identified as the sharp tip angle.

The artificial skin (thickness of 0.066 ~ 0.090mm pressure sensitive Teflon tape) wrapped in a layer of sharp edges measuring instrument on the mandrel, the mandrel to make a right angle with sharp edges, applying a force to the mandrel 6 n the , start the meter so that the spindle rotation, with 50% if the test is completely fragmented, the edge is considered to be sharp edges.
The artificial skin (thickness of 0.066 ~ 0.090mm pressure sensitive Teflon tape) wrapped in a layer of sharp edges measuring instrument on the mandrel, the mandrel to make a right angle with sharp edges, applying a force to the mandrel 6 n the , start the meter so that the spindle rotation, with 50% if the test is completely fragmented, the edge is considered to be sharp edges.

4.5 Umbrella pole, umbrellas fastness
Fixing the umbrella pole, with a dynamometer along the axial direction of the umbrella rod subjected to a predetermined uniform tension
