Category 3
3.1 Categories
Product use is divided into three categories.
Class Ⅰ --- For non-bearing requirements of the occasion.
Ⅱ class --- suitable for a certain load requirements, and there is resistance to high temperatures and resistance to compression creep is required. The products can also be used Ⅰ class
Product applications.
Ⅲ class --- suitable for higher load requirements, and there is compressive strength, resistance to compression creep is required. The products can also be used Ⅰ class and
Ⅱ class product applications.
3.2 Product classification
Products by combustion performance is divided into B, C, D, E, F grade in accordance with the provisions of GB 8624-2006.
4 Requirements
4.1 sheet products length and width limit deviations shall comply with the requirements of Table 1.
