(依据)

中国药典检验标准操作规范2019版,应该是小于等于0.3

国内药典是<0.3mg。

对比USP: until two consecutive weighings of the residue do not differ by more than 0.5 mg or until the percentage of residue complies with the limit in

the individual monograph.

EP: 2 consecutive weighings do not differ by more than 0.5 mg or until the percentage of residue complies with the prescribed limit.

都很明确的指出了是not more than , 也就是≤

应为<0.3mg。若表述为“不高于0.3mg”, 则是≤0.3mg。

常见的中英文表述和含义:

 NMT(Not more than)不高于

NLT(Not less than)不低于:≥

MT(More than )高于(以上):>

LT(Less than )低于(以下):<
