據(jù)包頭日報12月13日消息，截至目前，北方稀土先后主導(dǎo)和參與制定的國家及行業(yè)標(biāo)準(zhǔn)146項。其中，產(chǎn)品標(biāo)準(zhǔn)34項，方法標(biāo)準(zhǔn)99項，標(biāo)準(zhǔn)樣品13項，總數(shù)占到現(xiàn)行國家及行業(yè)標(biāo)準(zhǔn)的半數(shù)以上。這些標(biāo)準(zhǔn)的制定，完善了稀土標(biāo)準(zhǔn)體系，推動了稀土產(chǎn)業(yè)的規(guī)范發(fā)展，同時也增強了北方稀土在行業(yè)中的影響力和核心競爭力，為其參與稀土國際標(biāo)準(zhǔn)制定奠定了基礎(chǔ)。
長期從事稀土標(biāo)準(zhǔn)工作的北方稀土總工程師許濤表示，國際標(biāo)準(zhǔn)化組織稀土技術(shù)委員會成立后，北方稀土積極承擔(dān)和參與稀土國際標(biāo)準(zhǔn)的制定，爭取讓更多中國標(biāo)準(zhǔn)升級為國際標(biāo)準(zhǔn)。
