此題介紹中砝碼與美砝碼等級區(qū)分 The United States of america: 1, weight: E1, E2 grade, F1, F2, M1, M11, M2, M22, M3, a total of 9 grades. Difference and level is: Is in accordance with the uncertainty to points, namely, a correction value weights, is according to the error of indication, namely level weight without correction, as long as the indication error within this range are considered qualified. 2, other: Balance weight: types of material and non-magnetic stainless steel, non magnetic stainless steel, copper, iron chrome. Weight - cylinder, cone shape, shape, sheet shape, ring (ring) form, shape, riding a (great) shape Combined form of conventional combination of 5, 2, 2, 1 (according to user needs, can be any combination of) Precision grade - A (E2), two (F1 difference), F1 (three error), F2 (four), M1 (five) M2 (level six. If taking into account before we peer weights identity, can also be divided according to the rank weights. 1 a standard gauge (weight) 1) a standard weight. 2) E1 standard weight. 3) E1 standard weights. 4) E2 standard weight. 5) E2 standard weights. 2 two standard gauge (weight) 1) two standard weights. 2) F1 standard weight. 3) F1 standard weights. 3 three standard gauge (weight) 1) F2 standard weight. 2) F2 standard weights. 4 four standard gauge (weight) 1) M1 standard weight. 2) M1 standard weights. 3) M11 standard weight. 4) M11 standard weights. 5) M2 standard weight. 6) M22 standard weights. 7) M22 standard weight. 8) M22 standard weights. 5 five gauge (weight) Only one of 0 level weight. Therefore, we used the old rules of five weights, the above methods can be used to distinguish. In addition, the new rules only standard weight (such as weight) and weight (weight division level). Standard weight of a correction value, and weights only tolerance without correction 在中: 1、砝碼有等級區(qū)分:E1、E2、F1、F2、M1、M11、M2、M22、M3,共9個等級。等與級的區(qū)別在于: 等是按照不確定度來分的,即等砝碼有修正值,級是按照示值誤差來分的,即級砝碼沒有修正值,只要其示值誤差在此范圍內(nèi)都有認(rèn)為的。 2、其他: 天平砝碼:材質(zhì)種類— 無磁不銹鋼,非磁性不銹鋼,銅鍍鉻,鐵鍍鉻。 砝碼形狀— 圓柱體、圓錐體、板形、片形、圈(環(huán))形、騎形、條(棒)形 組合形式— 常規(guī)組合5、2、2、1,(可按用戶需求任意組合) 精度等級— 等(E2),二等(F1實差), F1 (三級允差),F(xiàn)2 (四級), M1 (五級). M2(六級 如果兼顧到家以前對等砝碼的認(rèn)同,也可以按照等級來劃分砝碼。 1. 等標(biāo)準(zhǔn)量具(砝碼) 1)等標(biāo)準(zhǔn)砝碼。 2)E1等標(biāo)準(zhǔn)砝碼。 3)E1級標(biāo)準(zhǔn)砝碼。 4)E2等標(biāo)準(zhǔn)砝碼。 5)E2級標(biāo)準(zhǔn)砝碼。 2. 二等標(biāo)準(zhǔn)量具(砝碼) 1)二等標(biāo)準(zhǔn)砝碼。 2)F1等標(biāo)準(zhǔn)砝碼。 3)F1級標(biāo)準(zhǔn)砝碼。 3. 三等標(biāo)準(zhǔn)量具(砝碼) 1)F2等標(biāo)準(zhǔn)砝碼。 2)F2級標(biāo)準(zhǔn)砝碼。 4. 四等標(biāo)準(zhǔn)量具(砝碼) 1)M1等標(biāo)準(zhǔn)砝碼。 2)M1級標(biāo)準(zhǔn)砝碼。 3)M11等標(biāo)準(zhǔn)砝碼。 4)M11級標(biāo)準(zhǔn)砝碼。 5)M2等標(biāo)準(zhǔn)砝碼。 6)M22級標(biāo)準(zhǔn)砝碼。 7)M22等標(biāo)準(zhǔn)砝碼。 8)M22級標(biāo)準(zhǔn)砝碼。 5. 五等量具(砝碼) 只有個0級砝碼。 所以,家習(xí)慣老規(guī)程的五等砝碼時,可采用上述方法行區(qū)分。 另外,新規(guī)程只有標(biāo)準(zhǔn)砝碼(等砝碼)和工作砝碼(級砝碼)之分。標(biāo)準(zhǔn)砝有修正值,而工作砝碼只有允差而沒有修正值 以上資料由上海實潤實業(yè)有限公司友情提供 供查詢:http://www.2233yksy.cn/ |
