編制說(shuō)明一、工作簡(jiǎn)況（-）任務(wù)來(lái)源根據(jù)2022年4月29日工業(yè)和信息化部發(fā)布的《工業(yè)和信息化部辦公廳關(guān)于印發(fā)2022年第一批行業(yè)標(biāo)準(zhǔn)制修訂和外文版項(xiàng)目計(jì)劃的通知》（工信廳科函[2022]94號(hào)）的要求，有色金屬行業(yè)標(biāo)準(zhǔn)《錫鉞芯塊化學(xué)分析方法第4部分：鋁、鉛、鐵、銘、鎂含量的測(cè)定電感耦合等離子體原子發(fā)射光譜法》修訂項(xiàng)目由全國(guó)有色金屬標(biāo)準(zhǔn)化技術(shù)委員會(huì)負(fù)責(zé)歸口，由西北稀有金屬材料研究院寧夏有限公司負(fù)責(zé)起草，該項(xiàng)目計(jì)劃編2O22-O23OT-YS,項(xiàng)目周期為18個(gè)月,完成年限為2023年10月。（二） 項(xiàng)目背景掃編芯塊作為核工業(yè)用二次中子源部件及壓水堆燃料元件，其用途不可替代。鋁、鉛、鐵、銘、鎂為錫繊芯塊產(chǎn)品中需要重點(diǎn)檢測(cè)的5種雜質(zhì)元素，對(duì)產(chǎn)品性能影響至關(guān)重要，其含量要求鋁不大于0.05%,鉛和鎬不大于0.04%,鐵不大于0.10%,鎂不大于0.02%,實(shí)現(xiàn)這—范圍是保障錫編芯塊產(chǎn)品性能的基本前提，因此精準(zhǔn)檢測(cè)錫編芯塊中鋁、鉛、鐵、鉆、鎂元素含量具有重要意義。目前，YS/T426.4-2000《錫編芯塊化學(xué)分析方法原子吸收光譜法測(cè)定鉛、鐵、銘、鎂量》及YS/T426.3-2000《錫鉞芯塊化學(xué)分析方法8劣基喳啡分光光度法測(cè)定鋁量帥作業(yè)過(guò)程均需要化學(xué)分離除去錫基體，步驟較為復(fù)雜，容易帶入試劑污染，造成分析方法不穩(wěn)定,且方法步驟冗長(zhǎng)，耗費(fèi)較多人力及時(shí)間。隨著產(chǎn)品工藝進(jìn)步及檢測(cè)設(shè)備更新，產(chǎn)品雜質(zhì)含量變低，設(shè)備檢測(cè)能力提高，運(yùn)用電感耦合等離子體原子發(fā)射光譜法，采用標(biāo)準(zhǔn)加入法消除基體干擾，無(wú)需分離錫基體，可同時(shí)測(cè)定鋁、鉛、鐵、銘、鎂5種元素，一并替代流程復(fù)雜的YS/T426.3-2000（比色法）及YS/T426.4-2000（原子吸收光譜法），大幅度提高工作效率。相比于原標(biāo)準(zhǔn)的原子吸收光譜法及分光光度法，電感耦合原子發(fā)射光譜法測(cè)定，更能達(dá)到快速、準(zhǔn)確的分析目的，適應(yīng)生產(chǎn)及科技的發(fā)展需求。本次修訂對(duì)錫編芯塊產(chǎn)業(yè)發(fā)展在產(chǎn)品檢測(cè)方面提供更有力的保障,有利于穩(wěn)定錫編芯塊產(chǎn)品質(zhì)量，提高中國(guó)錫繊芯塊的制造水平。同時(shí)，對(duì)我國(guó)核工業(yè)的發(fā)展也起到促進(jìn)作用。（三）
