Some standard content:
JG/T3039
—1997
This standard is equivalent to the Japanese Industrial Standard JISA4707—1988 "Light Iron Rolling Door" and is formulated in combination with the specific conditions of my country.
To facilitate the comparison of the new and old measurement units, this standard uses [] to indicate the old measurement units and values after the new measurement units. The main differences between this standard and the Japanese Industrial Standard are: the Chinese standard GB5824-86 "Building Door and Window Opening Dimension Series" is adopted in product specifications; aluminum alloy and color-coated steel plates and steel strips are added to the leaf material; classification by installation position is added to product classification; inspection rules and markings, packaging, transportation and storage are added; and installation dimension deviation and geometric tolerance content are added. This standard was first issued on February 20, 1997. This standard was proposed by the Standard and Quota Research Institute of the Ministry of Construction. This standard is under the jurisdiction of the China Building Standard Design Institute. This standard was drafted by the Hebei Provincial Construction Committee. The main drafting units of this standard are: Shijiazhuang Rolling Shutter Factory, Baoding Steel Window Factory, Hebei Aluminum Door and Window Factory, Xianxian Metal Products Factory, Shanhaiguan Metal Door and Window Factory.
The main drafters of this standard are: Feng Xiaofeng, Zhao Zhanming, Li Tongze. 446

Take out three leafs manufactured under the same conditions as the rolling door and window, connect them horizontally, and place them flat in the guide rail [see Figure 5 (a), and measure the span B equal to the inner width of the rolling door and window [see Figure 5 (b)]. Load the test piece evenly with the bending test load and loading sequence specified in Table 13 and Figure 5 (b) above the test piece, and keep it for 10 minutes. Under the load, measure the bending amount at the midpoint of the test piece [see Figure 5 (c), and determine the leaf bending strength according to Table 11. Use non-dispersed heavy objects such as lead bullets, sand bags, etc. for the load. The weight of each bag is 1.0~2.0kg. (a) Page bending test placement

The length of the specimen shall not be less than 1000mm. A steel bar with a diameter of 30mm is placed at each end of the span of 800mm as a support. A steel bar of the same size is placed at the midpoint of the specimen as a loading bar (see Figure 6). Then, the specimen is loaded at a speed of 98~198N10~20kgf per second until the load specified in Table 14 is reached, and the bending amount at the midpoint is measured. Then continue loading and measure the failure load of the middle column. Finally, determine its bending strength according to Table 12.
