在检验以体积标注的定量包装商品净含量时,JJF1070-2005《定量包装商品净含量计量检验规则》规定的计量检验方法有3种,即绝对体积法、密度法和相对密度法。通常对于流动性好、不易挂壁的液体,选用绝对体积法。而对于均匀混合、流动性不好、容易挂壁的液体,选用密度法或相对密度法。然而,在 In examining the volume of the net content of quantitative packaging products, JJF1070-2005 “quantitative measurement of net content of packaged goods inspection rules,” there are three kinds of measurement test methods, namely the absolute volume method, the density method and the relative density method. Usually for liquidity, easy to hang the liquid, the choice of absolute volume method. For uniform mixing, liquidity is not good, easy to wall the liquid, the choice of density or relative density method. However, at
