Material requirements for life jackets
Date: 2022-02-21Read: 4
professionallife jacketIn general, there are relevant certifications. In China, CCS is more common, while in foreign countries, CE certification is required. Generally, life jackets used by legitimate marine engineering enterprises need to have CE certification. Of course, certified life jackets are much more expensive, but personally, I think it's more reassuring to choose certified products for things related to life.
When we go out on a boat or engage in other water activities, for safety reasons, the first thing we need to know is where the life jacket is located and how to wear it. But besides that, whether the life jacket meets the requirements is more important, so what are the material requirements for the life jacket? Below, Dongfang Shipbuilding will introduce it to everyone.

1. Cloth, straps, and stitching. Cloth, straps, and stitching should be corrosion-resistant and should not be affected by seawater, oil, or fungal invasion. The fabric, straps, and stitching should be resistant to sunlight and not easily fade. The color fastness should meet the requirements specified in GB 250-1995 and GB251-1995: the light resistance should not be lower than level 5, the friction resistance should not be lower than level 3, and the seawater resistance should not be lower than level 4. The strength requirements for wrapping, binding, and stitching are shown in Table 1.
Table 1: Strength of Cloth, Straps, and Stitching
| serial number | Material Name | Project Name | requirement |
| 1 | Wrap cloth | Tensile breaking strength (longitudinal and latitudinal) | ≥ 784N/block |
| 2 | Binding straps | Tensile breaking strength | ≥ 1600N per root |
| 3 | suture | ≥ 19.6N/root |
2. Reverse reflective tape. The material of the reflective tape should meet the requirements of IMO A.658 (16).
3. Buoyant materials. Shape: The buoyancy material should not be loose granular material. High and low temperature stability: After withstanding 10 cycles of high and low temperatures, the buoyancy material should have no structural changes. Buoyancy loss: After immersion in diesel for 1 day and 7 days, the decrease in buoyancy of buoyancy materials immersed in diesel should not exceed 10%, and the decrease in buoyancy of buoyancy materials not immersed in diesel should not exceed 5%, and there should be no signs of damage such as wrinkling, cracking, expansion, or decomposition. Tensile breaking strength: The tensile breaking strength of buoyancy materials should not be less than 140kPa, and the decrease in tensile breaking strength after 10 high and low temperature cycles and 24 hours of immersion in diesel should not exceed 25%.
