我认为，一直以来，在市场上，无论是买方还是卖方都按公差+-2%的惯例执行的（包括澳洲公司以及其他公司）。从未出现过+-5%这么大的公差数。
注释：公差 deviation

I think that has been on the market. Both buyers and sellers are implemented by the practice of tolerance +-2% (including Australian companies and others). +-5% Has never appeared in such a large number of Tolerance.
Notes : tolerance deviation

别的也不说了，只是我觉得用“±”符号比较好
