標(biāo)準(zhǔn)解讀
《NB/T 11517-2024 礦用提升容器重要承載件無損檢測方法與判定規(guī)則》是一項(xiàng)針對礦用提升設(shè)備中關(guān)鍵承重部件進(jìn)行無損檢測的技術(shù)標(biāo)準(zhǔn)。該標(biāo)準(zhǔn)主要適用于煤礦、金屬礦山等場所使用的各種類型提升容器，如罐籠、箕斗等，其目的是通過科學(xué)合理的無損檢測手段來評估這些部件的安全性能，確保礦井提升系統(tǒng)的穩(wěn)定運(yùn)行和人員安全。
在內(nèi)容上，《NB/T 11517-2024》首先明確了適用范圍及引用文件，為后續(xù)章節(jié)提供了基礎(chǔ)依據(jù)。接著定義了術(shù)語和符號，統(tǒng)一行業(yè)內(nèi)對相關(guān)概念的理解。對于無損檢測方法的選擇，標(biāo)準(zhǔn)給出了具體指導(dǎo)，包括但不限于超聲波檢測、磁粉檢測、滲透檢測等多種技術(shù)，并詳細(xì)規(guī)定了每種方法的操作步驟、參數(shù)設(shè)置以及記錄要求，旨在保證檢測過程的一致性和準(zhǔn)確性。此外，還特別強(qiáng)調(diào)了對檢測結(jié)果的分析與評價原則，設(shè)定了缺陷允許的最大尺寸限制以及其他質(zhì)量控制指標(biāo)，幫助使用者準(zhǔn)確判斷被檢件是否滿足使用條件。
