標準解讀

《GB/T 23356-2024 卷煙 煙氣氣相中一氧化碳的測定 非散射紅外法》與《GB/T 23356-2009 卷煙 煙氣氣相中一氧化碳的測定 非散射紅外法》相比,存在多方面的調整和更新。這些變化主要體現(xiàn)在以下幾個方面:

  1. 術語定義:新版標準可能對一些專業(yè)術語進行了重新定義或補充說明,以確保表述更加準確、科學,符合當前技術發(fā)展水平及國際通用標準。

  2. 方法原理:雖然兩者都基于非散射紅外吸收光譜技術來測定卷煙主流煙氣中的一氧化碳含量,但2024版可能會細化實驗條件要求,比如溫度控制、氣體流速等參數(shù)設置,以提高測量精度和重復性。

  3. 儀器設備:隨著科學技術的進步,新版本對于使用儀器的具體型號、規(guī)格以及性能指標提出了更高要求。例如,可能增加了對檢測器靈敏度、響應時間等方面的規(guī)定,旨在通過更先進的設備獲得更為可靠的數(shù)據(jù)結果。

  4. 樣品處理:在樣品采集、保存及預處理環(huán)節(jié),新版標準或許會給出更加詳細的操作指南,并強調了避免污染的重要性,確保測試樣品能夠真實反映實際狀況。

  5. 數(shù)據(jù)分析與報告:針對數(shù)據(jù)處理流程、計算公式以及最終報告格式等內(nèi)容,2024版標準很可能進行了優(yōu)化和完善。這包括但不限于如何校正背景干擾、確定檢出限值以及如何正確表達不確定度等關鍵點。

  6. 安全防護措施:鑒于實驗室操作過程中可能存在潛在風險,新標準還特別加強了對工作人員健康保護的要求,如佩戴適當個人防護裝備、遵循正確的廢棄物處置程序等。

替換了ISO4387,引用相應的國家標準,便于對本文件的理解和執(zhí)行;

——更改了ISO8454:2024中重復性和再現(xiàn)性相關內(nèi)容(見第9章),以適合國內(nèi)現(xiàn)狀;

——增加了抽吸卷煙的準備相關內(nèi)容(見7.1),以適合我國國情便于標準的操作和執(zhí)行;

——增加了標準條件下每支卷煙一氧化碳的平均質量的計算公式[見公式(3)],便于在標準條件

下進行快速計算;

——增加了測試報告的詳細內(nèi)容(見10.2~10.5),適合我國國情便于標準的操作和執(zhí)行。

本文件做了下列編輯性改動:

——增加了資料性附錄A“方法的重復性限和再現(xiàn)性限”。
