此题介绍中砝码与美砝码等级区分 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、砝码有等级区分:E1、E2、F1、F2、M1、M11、M2、M22、M3,共9个等级。等与级的区别在于: 等是按照不确定度来分的,即等砝码有修正值,级是按照示值误差来分的,即级砝码没有修正值,只要其示值误差在此范围内都有认为的。 2、其他: 天平砝码:材质种类— 无磁不锈钢,非磁性不锈钢,铜镀铬,铁镀铬。 砝码形状— 圆柱体、圆锥体、板形、片形、圈(环)形、骑形、条(棒)形 组合形式— 常规组合5、2、2、1,(可按用户需求任意组合) 精度等级— 等(E2),二等(F1实差), F1 (三级允差),F2 (四级), M1 (五级). M2(六级 如果兼顾到家以前对等砝码的认同,也可以按照等级来划分砝码。 1. 等标准量具(砝码) 1)等标准砝码。 2)E1等标准砝码。 3)E1级标准砝码。 4)E2等标准砝码。 5)E2级标准砝码。 2. 二等标准量具(砝码) 1)二等标准砝码。 2)F1等标准砝码。 3)F1级标准砝码。 3. 三等标准量具(砝码) 1)F2等标准砝码。 2)F2级标准砝码。 4. 四等标准量具(砝码) 1)M1等标准砝码。 2)M1级标准砝码。 3)M11等标准砝码。 4)M11级标准砝码。 5)M2等标准砝码。 6)M22级标准砝码。 7)M22等标准砝码。 8)M22级标准砝码。 5. 五等量具(砝码) 只有个0级砝码。 所以,家习惯老规程的五等砝码时,可采用上述方法行区分。 另外,新规程只有标准砝码(等砝码)和工作砝码(级砝码)之分。标准砝有修正值,而工作砝码只有允差而没有修正值 以上资料由上海实润实业有限公司友情提供 供查询:http://www.21fama.com/ |
