Fire Protection Rating Of Rotomolded Products
The fire protection grade of rotational molded products is divided according to the combustion performance of the material. This standard is usually set by national standards or industry standards. At present, the more common fire protection rating classification system is based on the UL94 standard, which divides the fire protection rating into multiple levels. Among them, the three levels related to rotational molding products are mainly V-0, V-1, and V-2. These The grade reflects the material's burning and extinguishing characteristics in a flame.
Detailed explanation of fire protection grade of rotational molding products
V-0 level:
Definition: V-0 is the highest level of fire protection, which means that under a vertical burning test, the material’s burning time does not exceed 10 seconds, and the self-ignition extinction time does not exceed 30 seconds. At the same time, there will be no burning objects during the entire test. fall.
V-1 level:
Definition: The fire resistance of V-1 grade is slightly lower than V-0, but after the vertical burning test, even if the flame is extinguished, no burning matter is allowed to drip.
Application scenarios: V-1 grade rotational molding products are suitable for areas that have certain requirements for fire resistance but do not need to meet the strict standards of V-0 grade, such as office furniture.
V-2 level:
Definition: The V-2 level is the lowest of the three levels. It requires that the flame of the sample extinguishes itself within 60 seconds after two 10-second burning tests, but burning materials are allowed to drip.
Application scenarios: V-2 grade rotational molding products are suitable for occasions that have certain requirements for fire resistance but do not require high standards, such as building interiors, household appliances, etc.
Things to note
When selecting rotomolded products, the appropriate fire protection level needs to be determined based on specific application scenarios and needs. High-demand areas should choose V-0 grade rotational molding products, while general areas can choose V-1 or V-2 grade products.
In addition to the fire rating, factors such as the cost and performance of the product and the reliability of the supplier also need to be considered.
The classification and testing methods of fire protection grades may change as national standards are updated, so you should refer to the latest standards when selecting products.
To sum up, the fire protection grade of rotomolded products is divided according to the combustion performance of the material, and is mainly divided into three grades: V-0, V-1, and V-2. These grades provide clear reference standards for the fire performance of rotomolded products in different application areas.
