Umbrella safety standards
Scope This standard specifies the safety performance requirements, test methods, and inspection rules for sunny umbrellas. 5D Tempered Glass,Aluminum Tempered Glass ,Best Tempered Glass,Matte Tempered Glass WCH Temper Glass Co., Ltd , https://www.temperglasswch.com
This standard applies to textile umbrellas, plastic umbrellas and umbrella umbrellas made of different materials and straight umbrellas.
Normative references The following documents contain provisions which, through reference in this standard, constitute provisions of this standard. For dated references, subsequent amendments (not including errata content) or revisions do not apply to this standard. However, parties that have reached an agreement based on this standard are encouraged to study whether the latest versions of these documents can be used. . For undated references, the latest version is applicable to this standard.
Evaluation of the performance of textiles against ultraviolet radiation Safety performance requirements The minimum size (diameter or length) of the umbrella cap (umbrella top sleeve) size umbrella cap (umbrella top sleeve) shall not be less than 9mm, and the height shall not be greater than 80mm.
The umbrella cap (umbrella top cover) of the child umbrella must be spherical or round in shape, and its top diameter must not be less than 15 mm.
Umbrella beads umbrella head must be spherical or arc-shaped end, the diameter must not be less than 3mm, child umbrella umbrella head diameter of not less than 5 mm.
When the umbrella is open, the umbrella head must not come off on its own.
Switching performance After the umbrella is opened manually, the springs and the link springs shall all play a positioning role. The umbrellas shall be closed and the umbrellas shall not be allowed to lose control. All parts and components shall not be deformed or damaged which may affect normal use.
The use of safety requirements in the use of the umbrella accessible parts do not allow the sharp angle of the human body, sharp edges.
The combination of umbrella poles, umbrella handles, fastness umbrella poles, and umbrella handles should be able to withstand 150n of static tension without shifting.
The UV protection performance of the umbrella surface is identified as a product with UV protection function. The UV protection capability of the umbrella surface must reach upf>30 and t(uva)av<5%.
Test Method Umbrella Cap (Umbrella Top Sleeve) The minimum size of the top end (diameter or length) is measured directly with a precision 0.02 mm vernier caliper, measured three times at different locations, and expressed as the minimum value of the measurement result.
The height is measured directly with a vernier caliper with an accuracy of 0.02 mm. The umbrella is opened and the distance from the tip of the umbrella cap to the canopy is measured and measured three times at different positions. The maximum value of the measurement result is expressed.
The diameter of the umbrella head is directly measured with a precision 0.02 mm vernier caliper, and any measurement of the five umbrella heads is taken and expressed as the minimum value of the measurement result.
Continuously switch the umbrella 10 times to check if the umbrella head is falling off.
Switching performance Handle the handle three times, then switch the umbrella five times.
Use safety requirements to align sharp angles with the measuring points of the sharp point meter and check that the point being tested can be inserted into the point meter to the specified depth. The depth of insertion of the tested tip determines the sharpness. If the tip can touch the 0.38mm±0.02mm sensor head with concave measuring cover, and overcome the spring force of 2.5n, make the sensor head move by 0.12mm±0.02mm, the indicator light of the sharp point meter is on, then the tip is determined as sharp angle.
Artificial skin (a pressure-sensitive polytetrafluoroethylene tape with a thickness of 0.066 to 0.090 mm) is wound on the mandrel of a sharp edge measuring instrument so that the mandrel is at right angles to the sharp edge and 6 n of force is applied to the mandrel. , Turn on the meter to rotate the mandrel once. If the test is 50% completely split, the edge is considered to be a sharp edge.
Umbrella poles and umbrella handles are fastened to fix the umbrella poles, and the dynamometer is used to uniformly apply a predetermined pulling force along the axial direction of the umbrella poles.
The UV protection performance of the umbrella surface was measured according to the provisions of gb/t 18830-2002.
Inspection Rules The items specified in this standard are type inspection items.
At least one type inspection shall be conducted every year during normal production, and one type of inspection shall also be carried out when one of the following situations occurs:
After the formal production, if the structure, material, and process are greatly changed, the product performance may be affected; when the product is suspended for more than half a year and the production is resumed, the factory inspection result and the last type inspection have When there is a large difference, when a national quality supervision agency or customer proposes a type inspection request.
The items of type inspection are all items of this standard. The samples of type inspection shall be randomly selected from the qualified batches of the factory inspection. Each time 3 samples are selected for type inspection, they shall all comply with the provisions of this standard.
