Swimming rings are not lifebuoys, and they must not be used as life-saving appliances. The national standards of swimming rings and lifebuoys are different. The lifebuoy plays a life-saving role and has many auxiliary functions. Swimming rings are defined as aquatic toys, and only toy standards are implemented.
Therefore, compared with the real life buoy, the toy swimming ring is easy to leak, has poor compression resistance and is easy to burst. The plastic surface is slippery in water and difficult to grasp. It can only play a certain auxiliary or protective role in water leisure sports, and it is very dangerous if it is brought into deep water.

Selection and purchase
Life buoy is a main life-saving equipment, which is usually used as a necessary product for safety protection in water disaster relief and related production operations.
There are mainly three kinds of lifebuoys in China: polystyrene wrapped lifebuoys, polyurethane-polyethylene composite lifebuoys and skin polyethylene lifebuoys.
Because the quality of lifebuoys is uneven, the price is different and the application scope is different, you should carefully choose lifebuoys that meet the configuration requirements when purchasing.
1. Qualified lifebuoy products shall have relevant material inspection reports, type test reports and ship bolt inspection certificates.
2. If conditions permit, merchants are required to check the weight, sewing quality, strength, floatability, high temperature resistance and damage resistance of lifebuoy according to the requirements of standards and specifications.
