New standard life jackets. A life jacket, also known as a life vest, is a type of life-saving clothing designed similar to a vest, made of nylon fabric or neoprene, buoyant or inflatable materials, reflective materials, etc. The general service life is 5-7 years, which is one of the life-saving equipment on board. It is generally vest type, made of foam plastic or cork. Wearing it on the body has sufficient buoyancy to allow the head of the drowning person to protrude from the water surface.

Usually, the ones we use are marine life jackets. Its interior is made of EVA foam material, which is compressed and 3D molded to a thickness of about 4 centimeters (the domestically produced 56 thin hair materials are about 57 centimeters thick). Life jackets produced according to standard specifications. Each has its own buoyancy standard: generally 7.5 kilograms/24 hours for adults and 5 kilograms/24 hours for children, in order to ensure that the water surface is above the chest. The surface is made of materials with good water resistance and breathability. When selecting, in addition to paying attention to buoyancy, attention should also be paid to whether the cross band interface is damaged to prevent it from floating up without gravity after entering the water.

DFY-III type life jacket, the new standard life jacket is designed and manufactured in accordance with the requirements of IMO MSC.200 (80), MSC.207 (81), and GB4303-2008 standards. It has a buoyancy greater than 155N and can be worn by personnel weighing 140kg with a chest circumference of 1750mm. Equipped with a life-saving whistle. This life jacket is equipped with a throwable floating strap, which can be attached to another person's life jacket or life jacket in the water. It also comes with a salvageable lifting ring, allowing rescue personnel to lift the wearer out of the water and into a lifeboat or life raft. This regulation was implemented on July 1, 2010, and the life jacket is suitable for adults to wear. This product has been recognized by CCS and GL, and has obtained CCS and EC certification.

Life jackets are classified according to their use: 1. Marine Lifejacket, (Marine Child Lifejacket), suitable for saving lives of various personnel along the coast and inland rivers. The buoyancy of the life jacket is greater than 113N. After soaking in water for 24 hours, the buoyancy loss of the life jacket should be less than 5%. Life jacket buoyancy material: polyethylene foam plastic. The new type of marine life jacket is designed and manufactured in accordance with the requirements of IMO MSC207 (81) and MSC200 (80), which came into effect on July 1, 2010. 2. Marine work Lifejacket, suitable for various personnel working along the coast and inland rivers. The buoyancy of the life jacket should be greater than 75N. After soaking in water for 24 hours, the buoyancy loss of the life jacket should be less than 5%. Life jacket buoyancy material: polyethylene foam plastic. 3. Leisure life jacket: also known as water sports life jacket, the fabric is mostly made of chloroprene rubber composite material, with multiple color combinations, fashionable and beautiful. Mainly suitable for water play, learning swimming, drifting, fishing, etc., wearing protective clothing for lifesaving purposes. Buoyancy material: polyethylene foam.
