A Life Jacket, also known as life -saving vest, is a kind of rescue of life. It is designed with a vest, using nylon fabrics or neoprene, buoyancy materials or inflatable materials, reflective materials.So what is the standard for life jackets?What are the categories?
Life jacket standard
With the approval of the full office (1996) of the National Industrial Product Production License Office (1996), the Ministry of Communicationss shipping life equipment quality supervision and testing and testing center is a quality inspection unit for the production license production license production license.
Conditions must be possessed by enterprises to obtain a life jacket production license:
1. If the business administrative department is issued, the business scope includes the business license of the production of life jacket products.
2. Product quality meets the requirements of the current national and industry standards, and the requirements of international maritime organization resolutions and ship inspection specifications.
Third, have the correct and complete product pattern and technical documents.
Fourth, the production equipment, process equipment, measurement and inspection methods that ensure the quality of the product.
Fifth, with professional and technical personnel, skilled technical workers, and measurement and inspectors for normal production.6. Have a sound and effective quality management system.
The main classification of life jacket
Marine Lifejacket, (Marine Child Lifejacket), is suitable for life -luminating life along the ocean coast and inland river personnel. The buoyancy of life jackets is greater than 113N for 24 hours.Lifeline buoyancy material: polyethylene foam plastic.
Marine Work Work Lifejacket is suitable for work and use of various people along the coast and inland river.The buoyancy of life -saving clothing is greater than 75N. After soaking for 24 hours in the water, the buoyancy loss of life clothing should be less than 5%.
Leisure life jacket: Some are also called Water Sports Lifejacket. The fabric is mostly composite for chlorprons rubber, with a variety of color matching, fashionable and beautiful.It is mainly suitable for waters to play, learning swimming, rafting, fishing, etc. to wear life protection effects.
Generally, it belongs to the sea life jacket.It uses EVA foam material inside, which has been compressed by 3D stereo. Its thickness is about 4 cm (domestic products are 5-6 thin hair materials, which is about 5-7 cm thick).The life jackets produced according to the standard specifications have its buoyancy standards: Generally, it is 7.5 kg/24 hours, and children are 5 kg/24 hours, so as to ensure that the surface of the chest is surfaced.
How to use: Put on the body of the life -saving clothing outlet out of the body; pull the zipper, tighten the front collar tie with both hands, and bind a good neck zone;prison.
Aviation
The inflatable life jacket is the pulp rope on the inflatable device by hardening, so that the lever is transferred to no less than 90 degrees. The piercing needle pierced the diaphragm in the high -pressure gas storage cylinder (one -time, replaceable), the high -pressure carbon dioxide gas is pushed into the airbag, the gas swells, the gas swellingLater, buoyancy is generated to achieve the purpose of life.
Warm life jacket
The two patent certificates issued by the State Intellectual Property Office, the patent name, waterproof and heating and heating life jacket issued by the State Intellectual Property Office, the patent name is waterproof and heating and heating life jacket. The issuance time is March 2013.There are 13 components in life jackets, with tops, pants, boots, and gloves.The inflatable airbags can be removed, and they can be inflated at any time, practical and convenient.
Safe clothes selection
"Safety first" is an eternal theme, so it is particularly important for the standard buoyancy.If it is a boat, whether it is rivers or lakes and sea, you will swim or wear a life -saving vest, because if you have a dangerous situation, plus wind waves or cold, you are proficient in water properties in real time, and often you ca n’t have a 100 % incident.
Life jackets are generally divided into sea life jackets, automatic expansion -type life jackets, and sketch fishing.
1. Sea life jacket: It is also the most useful one we use. He uses EVA foam material inside, which is compressed by 3D three-dimensional molding. Its thickness is about 4 cm.5-7 cm), the life jackets produced in accordance with the standard specifications have its buoyancy standards. Generally, adults are 7.5 kg/24 hours, which means that adults can still reach 7.5 kg after wearing it in the sea for 24 hours.Essence
2. Automatic expansion -type life jacket: Generally use it as a boat fishing, and use double -layer high -strength chemical materials inside. In case of water falling, press the right button on the right, automatically inhale the air on the left, and the reflector will store the air until it is full.The buoyancy of life jackets is 10 kg/24 hours, but it should be tried to prevent it from contacting the reef to prevent damage.
3. Big fishing cross -arm life jacket: Big fishing supplies, he has a pair of buttons in front of him, and he needs to pull it when you put it on.In addition, there is a pair of oval glowing body on the chest or shoulders of life jackets, which are mainly used for maritime assistance. Therefore, you should pay attention to whether to open the sewing when choosing, and then consider the tone of the fabric.
