再生鋼鐵原料的夾雜物首先用目視感官進行檢驗，估算質量占比。當不能確定是否符合要求時，按6.5.2檢驗。 6.5.2 再生鋼鐵原料的夾雜物檢測程序如下： a) 抽取原料樣品，稱量、記錄樣品質量m； b) 對夾雜物實施分揀，記錄非金屬物質木廢料、廢紙、廢塑料、廢橡膠、廢玻璃、石塊等的質量m1； c) 使用2 mm篩孔的篩子對原料樣品進行篩分，記錄粒徑不大于2 mm的粉狀(灰塵、污泥、木屑、纖維末等)物質的質量m2； d) 通過磁選裝置，對篩分出來的粉狀物質進行磁選，記錄磁選出的金屬(鐵粉、鋼屑、氧化鐵等)物質的質量m3。 按式(1)計算夾雜物含量(W1)，數值以％表示。 (1) 式中： W1——夾雜物含量； m1——大塊非金屬夾雜物質量，單位為千克(kg)； m2——粒徑不大于2 mm的粉狀物質質量，單位為千克(kg)； m3——粒徑不大于2 mm的金屬物質質量，單位為千克(kg)； m——樣品質量，單位為千克(kg)。 7 驗收規則 7.1 組批 每個檢驗批應由同一類別、同一牌號的再生鋼鐵原料組成；每個檢驗批應不少于300 t。 7.2 檢驗項目 應對再生鋼鐵原料的放射性污染物、爆炸性物品、危險廢物、夾雜物進行檢驗。 7.3 取樣 再生鋼鐵原料檢驗項目的取樣應符合表4的規定。 表4 再生鋼鐵原料檢驗項目取樣 檢驗項目 取樣規定

選擇能夠代表當地正常天然輻射本底狀態，無放射性污染的平坦空曠地面的3～5個點(可作為固定調查點)作為測量點。 C.2.1.3 將測量儀之測量探頭置于測量點上方距地面1 m高處，測定其外照射貫穿輻射劑量率，每10 s讀取測量值1次，取10次讀數的平均值作為該點的測量值，取各測量點測量值的算術平均值作為正常天然輻射平均值。 C.2.2 巡回檢測 C.2.2.1 原料在經口岸通道前，應進行放射性污染的巡回檢測。巡回檢測時，盡可能地將測量儀器接近被測物表面或裝載原料的集裝箱、車體、倉體等的表面，對被測物的周體表面進行巡回檢測。 C.2.2.2 在巡回檢測時已發現放射性明顯超過三項檢測指標管理限值時，判定為不合格。對已發現放射性污染超過三項檢測指標管理限值時，不再進行分檢或挑選。 C.2.3 測試點分布 C.2.3.1 對于裝運原料的汽車、火車、集裝箱、輪船或成堆攤放的散裝原料，均可按網格法布點(見圖C.1)。用直接測量法進行外照射貫穿輻射劑量率和表面污染的檢測。
