In China, the code name of wooden fire doors usually follows certain standard naming rules, which are convenient for identification and application in architectural design, material selection, construction and maintenance. The product model or designation of a wooden fire door contains information about the performance class and characteristics of the door itself.
Under the standardized nomenclature system, the typical form of the code of a wooden fire door may be "A, B, C-fire rating-specification-size-model". Among them, "A, B, C" represents different fire resistance stability grades - "A" grade represents the highest fire resistance, usually 1More than 5 hours; Grade "B" is usually around 1 hour; The "C" grade is generally 05 hours. The increased fire resistance level means that fire doors can remain structurally intact and insulated for longer in high-temperature environments.
For example, the code name of a wooden fire door might be "Grade A-B-1-2010", where "Grade A" means it has the highest level of fire stability, "B" may be the series code given by the manufacturer, "1" may mean that this is the first model in the series, and "2010" may represent the year the product was designed or modified.
In practice, these codes can help designers, engineers, or installers understand the basic properties of the product in question. When it is time to purchase or replace a wooden fire door, this code information can be used to quickly find a product that matches the original door to ensure the fire integrity of the building.
It should be noted that in addition to the model code that meets the national standard, the wooden fire door also needs to pass the corresponding product quality certification, such as the China Fire Product Conformity Assessment Center (CCCF) certification, on the side of the door or in an inconspicuous position usually has the relevant certification mark or sticker, printed with the certificate number and other information.
In summary, the code name of a wooden fire door is its "identity card", and the information it contains guides the user to understand the fire rating and other important attributes of the door. Although the code name may change slightly between products, it is reasonably set in accordance with national standards in order to better serve fire safety management. Therefore, it is important to understand and correctly identify these codes when choosing a wooden fire door.
