Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 22350-2008 "Formed plywood."
Compared with GB/T 22350-2008, the main technical contents of this standard are as follows.
--- Added an introduction;
--- The definitions of "unidirectional force forming plywood" and "multidirectional force forming plywood" have been added to the definition of the term;
--- Modify the allowable value of the form deviation in Table 2 to improve the degree of deformation of the molded plywood;
--- Delete the "non-forced molded plywood except for the above 3 items" in the note of Table 2;
--- Modify the maximum single width of the cracks in Table 3 and the maximum width of overlapping/separated seams in core stacking;
--- Adjustments to the test equipment and test methods for deviations in shape and position. The distortion test bench was removed and increased in the form deviation tester
Added twist distortion test function, modified the test method of distortion degree;
--- Modify the sampling plan for physical and chemical performance testing;
--- Modify the judgment of the physical and chemical performance test results, the physical and chemical performance indicators are divided into heavy defects and light defects, and the provisions
Set and review requirements.
