Scope
This standard specifies the requirements, test methods, metrological control, and marking, packaging, transport, and storage of discontinuous totalizing automatic weighing instruments (totalizing hopper weighers) (hereinafter referred to as instruments). This standard applies to instruments with a hopper-type load receptor, which divide a batch of bulk material into discrete loads, sequentially weigh each discrete load, totalize the weighing results, and discharge the discrete loads.
本标准规定了非连续累计自动衡器(累计料斗秤)(以下简称衡器)的要求、试验方法、计量控制、和标志、包装、运输、贮存。本标准适用于具有料斗式承载器，通过把一批散料分成不连续的载荷，依次称量每份不连续载荷的质量，累计称量结果，并将不连续载荷卸出的衡器。

This standard QB/T 1078-2004 replaces QB/T 1078-1991 and modifies OIML R 107-1997. It specifies technical requirements, test methods, metrological control, and marking/packaging for discontinuous totalizing automatic weighing instruments (totalizing hopper weighers). Instruments are classified into four accuracy classes: 0.2, 0.5, 1, and 2, with corresponding maximum permissible errors. The standard details test procedures including material tests, simulation tests, and influence factor tests, and adds requirements for packaging, transport, storage, and modifications to EMC tests.
本标准QB/T 1078-2004替代了QB/T 1078-1991，修改采用OIML R 107-1997国际建议。标准规定了非连续累计自动衡器（累计料斗秤）的技术要求、试验方法、计量控制及标志包装等。衡器分为0.2、0.5、1、2四个准确度等级，并给出了相应的最大允许误差。标准详细描述了物料试验、模拟试验、影响因子试验等测试程序，并增加了包装运输储存要求及电磁兼容试验的修改。

本标准规定了非连续累计自动衡器(累计料斗秤)(以下简称衡器)的要求、试验方法、计量控制、和标志、包装、运输、贮存。
本标准适用于具有料斗式承载器，通过把一批散料分成不连续的载荷，依次称量每份不连续载荷的质量，累计称量结果，并将不连续载荷卸出的衡器。
衡器分为四个准确度等级: 0.2, 0.5, 1, 2。
每个准确度等级的最大允许误差应为表1中的对应值，其值应化整到最接近的累计分度值上。
本标准修改采用国际法制计量组织107号国际建议(OIML R 107-1997)《非连续累计自动衡器(累计料斗秤)》。
This standard specifies the requirements, test methods, metrological control, and marking, packaging, transport, and storage of discontinuous totalizing automatic weighing instruments (totalizing hopper weighers).
This standard applies to instruments with a hopper-type load receptor, which divide a batch of bulk material into discrete loads, sequentially weigh each discrete load, totalize the weighing results, and discharge the discrete loads.
Instruments are divided into four accuracy classes: 0.2, 0.5, 1, 2.
The maximum permissible error for each accuracy class shall be the corresponding value in Table 1, and the value shall be rounded to the nearest totalization scale interval.
This standard modifies the International Recommendation OIML R 107-1997 of the International Organization of Legal Metrology, 'Discontinuous totalizing automatic weighing instruments (totalizing hopper weighers)'.
