現(xian)在我們執行(xing)(xing)的包(bao)裝(zhuang)檢測標準（海運）主要分為(wei)2大(da)類(lei)(lei)：一(yi)類(lei)(lei)是《SN0449.2—95海運出口(kou)危(wei)(wei)險貨物(wu)(wu)包(bao)裝(zhuang)檢驗規(gui)程(cheng)(cheng)———性能(neng)檢驗》，主要是對危(wei)(wei)險貨物(wu)(wu)包(bao)裝(zhuang)容器(qi)進行(xing)(xing)性能(neng)檢驗；另一(yi)類(lei)(lei)是對非危(wei)(wei)險貨物(wu)(wu)包(bao)裝(zhuang)容器(qi)進行(xing)(xing)性能(neng)檢驗的標準。對紙箱和紙板桶(tong)來說， 一(yi)個(ge)(ge)是《SN/T0262—93 出口(kou)商(shang)(shang)品(pin)運輸包(bao)裝(zhuang)瓦楞紙箱檢驗規(gui)程(cheng)(cheng)》；另一(yi)個(ge)(ge)是《SN/T0270—93 出口(kou)商(shang)(shang)品(pin)運輸包(bao)裝(zhuang)紙板桶(tong)檢驗規(gui)程(cheng)(cheng)》。

                            
    在《SN0449.2—95 海運出口危(wei)險貨物包(bao)裝檢驗(yan)規程———性能(neng)檢驗(yan)》（簡稱SN0449.2—95 標準）中規定，按其所裝的危(wei)險貨物的危(wei)險程度分為3 個類別：
                           
     I 類包裝適用于高度(du)危險的貨(huo)物；II 類包裝適用于中(zhong)度(du)危險的貨(huo)物；III 類包裝適用于低度(du)危險的貨(huo)物。
