標(biāo)準(zhǔn)解讀

《GB/T 17664-2024 木炭》相較于《GB/T 17664-1999 木炭和木炭試驗方法》,主要在以下幾個方面進行了更新與調(diào)整:

一、標(biāo)準(zhǔn)名稱的簡化。新版本去掉了“和木炭試驗方法”的表述,僅保留“木炭”,更加聚焦于木炭本身的標(biāo)準(zhǔn)設(shè)定。

二、技術(shù)內(nèi)容上的修訂。根據(jù)近年來國內(nèi)外木炭生產(chǎn)技術(shù)的發(fā)展以及市場需求的變化,《GB/T 17664-2024 木炭》對原標(biāo)準(zhǔn)中的部分內(nèi)容進行了更新或補充,包括但不限于:

  • 對木炭分類進行了細化,增加了新的種類描述。
  • 更新了部分術(shù)語定義,使之更加準(zhǔn)確地反映當(dāng)前行業(yè)實踐。
  • 調(diào)整了某些物理性能指標(biāo)的要求,如灰分含量、揮發(fā)份等,以適應(yīng)更廣泛的應(yīng)用場景。
  • 引入了一些新的檢測方法和技術(shù),提高了測試結(jié)果的準(zhǔn)確性與可靠性。

三、試驗方法的改進。雖然新版標(biāo)準(zhǔn)名稱不再直接提及“試驗方法”,但其實驗部分依然存在且有所增強,具體表現(xiàn)為:

  • 優(yōu)化了現(xiàn)有的一些經(jīng)典測定流程,使其操作更加簡便快捷。
  • 增加了幾種新型快速檢測手段,旨在縮短分析時間的同時保證數(shù)據(jù)質(zhì)量。
  • 針對特定類型的木炭產(chǎn)品,制定了專門的評價體系,增強了標(biāo)準(zhǔn)適用性。
