Pencil hardness
Fix the test piece on a horizontal stand with the coating surface upward,hod the pencil at an angle of approximately 45 degrees as shown in fig.1,while pressing the coating surface as strongly as possible to the degree so as the core not to be broken and press out forward to the testing person at a uniform speed by approximately 1 CM to scratch the coating surface. Make the press-out speed approximately 1 cm/s.
At each once scratching newly polish the top end of core of pencil,and repeat the test five times by pencil of the same concentration symbol.
When in five-time tests the rubbing flaw reaching the paint film twice or more is not confirmed,with exchanging with the pencil with upper concentration symbol carry out the test similarly,select the pencil by which the rubbing flaw of paint film becomes not less than twice and record the concentration symbol lower by one step than that of the pencil as the pencil hardness of paint film.
NOTE： The rubbing flaw means the flaw which slightly bite in the surface of paint film,and the dent of paint film by applying pressure is not the object.Remove the carbon powders by eraser so as not to flaw the paint film at the tested portion,observe visually vertically to the rubbing direction from the angle of 45 degrees to the surface of test piece,and take the judgeable flaw as the “rubbing flaw”.

铅笔硬度
Fix the test piece on a horizontal stand with the coating surface upward,将铅笔固定在水平台上，涂层表面朝上hod the pencil at an angle of approximately 45 degrees as shown in fig.1,斜度约为45度，如图1所示while pressing the coating surface as strongly as possible to the degree so as the core not to be broken 尽力压涂层表面，压至铅芯不开裂and press out forward to the testing person at a uniform speed by approximately 1 CM to scratch the coating surface以固定的速度推离测试者1cm.削除涂层表面 Make the press-out speed approximately 1 cm/s.推离速度约为1 cm/s
At each once scratching newly polish the top end of core of pencil,and repeat the test five times by pencil of the same concentration symbol.
一次削亮铅芯顶端，在相同的轴心重复试验五次
When in five-time tests the rubbing flaw reaching the paint film twice or more is not confirmed,五次试验中，削纹到达涂层超过两次以上，试验失败with exchanging with the pencil with upper concentration symbol carry out the test similarly,更换铅笔，在较大的轴心进行类似地试验select the pencil by which the rubbing flaw of paint film becomes not less than twice挑选削纹到达涂层少于两次的铅笔 and record the concentration symbol lower by one step than that of the pencil as the pencil hardness of paint film.记录较少的轴心，作为涂层的铅笔硬度
