API會(huì)標(biāo)是美國(guó)石油學(xué)會(huì)的學(xué)會(huì)產(chǎn)品標(biāo)志，始于1924年，目的是為了鑒定生產(chǎn)的設(shè)備、材料，并提供能符合API質(zhì)量體系和產(chǎn)品標(biāo)準(zhǔn)的生產(chǎn)企業(yè)。該標(biāo)志經(jīng)美國(guó)注冊(cè)登記，未經(jīng)許可任何人不得使用。API的一項(xiàng)重要任務(wù)，就是負(fù)責(zé)石油和天然氣工業(yè)用設(shè)備的標(biāo)準(zhǔn)化工作，以確保該工業(yè)界所用設(shè)備的安全、可靠和互換性。制定協(xié)調(diào)標(biāo)準(zhǔn)是API**早和成功的項(xiàng)目之一，自1924年發(fā)布第1個(gè)標(biāo)準(zhǔn)開(kāi)始，API現(xiàn)在已發(fā)布了500個(gè)標(biāo)準(zhǔn)。API是ANSI認(rèn)可的標(biāo)準(zhǔn)制定機(jī)構(gòu)，其標(biāo)準(zhǔn)制定遵循ANSI的協(xié)調(diào)和制定程序準(zhǔn)則，API還與ASTM聯(lián)合制定和出版標(biāo)準(zhǔn)，此外，API積極參加適合全球工業(yè)的ISO標(biāo)準(zhǔn)的制定工作，是ISO/TC671SC9井口設(shè)備和管線閥門(mén)的秘書(shū)處。API標(biāo)準(zhǔn)經(jīng)常被認(rèn)為是“安全和可靠性”的同義詞。API682標(biāo)準(zhǔn)——針對(duì)機(jī)械密封和密封供應(yīng)系統(tǒng)的，一直以來(lái)被廣泛應(yīng)用，同時(shí)還在工業(yè)應(yīng)用范圍以外被引用。新版API682標(biāo)準(zhǔn)的編寫(xiě)者指出，新標(biāo)準(zhǔn)從來(lái)沒(méi)有考慮工業(yè)外的應(yīng)用范圍，并明確了API682標(biāo)準(zhǔn)適用范圍，這些標(biāo)準(zhǔn)*適用于泵機(jī)的密封系統(tǒng)，而不適用于攪拌機(jī)或壓縮機(jī)。而且此標(biāo)準(zhǔn)適用于石油天然氣以及（石油）化工行業(yè)，而不適用于供水或者食品行業(yè)。</p><p>
