标准范围

ISO 4787:2010提供了玻璃制容量仪器的测试、校准和使用方法，以便在使用中获得最佳精度。各容量仪器的国际标准（ISO 385、ISO 646、ISO 835、ISO 1042和ISO 4788）包括容量定义条款；这些条款充分详细地描述了操作方法，以定义容量，而不会产生歧义。ISO 4787:2010包含补充信息。ISO 4787:2010中的程序适用于标称容量在0.1 ml至10000 ml范围内的容量仪器。这些包括:没有细分的单体积移液管（见ISO 648）；带刻度的测量移液管和稀释移液管，带有部分或全部细分（见ISO 835）；滴定管（见ISO 385）；容量瓶（见ISO 1042）；和刻度量筒（见ISO 4788）。对于容量低于0.1 ml的容量仪器，如微型玻璃器皿，不建议使用该程序进行测试。ISO 4787:2010未具体涉及ISO 3507中规定的比重瓶。然而，大多数情况下，比重瓶的校准也可以遵循玻璃器皿体积测定程序。

ISO 4787:2010 provides methods for the testing, calibration and use of volumetric instruments made from glass in order to obtain the best accuracy in use.The International Standards for the individual volumetric instruments (ISO 385, ISO 646, ISO 835, ISO 1042 and ISO 4788) include clauses on the definition of capacity; these clauses describe the method of manipulation in sufficient detail to define the capacity without ambiguity. ISO 4787:2010 contains supplementary information.The procedures in ISO 4787:2010 are applicable to volumetric instruments with nominal capacities in the range of 0,1 ml to 10 000 ml. These include: single-volume pipettes (see ISO 648) without subdivisions; graduated measuring pipettes and dilution pipettes, with partial or complete subdivisions (see ISO 835); burettes (see ISO 385); volumetric flasks (see ISO 1042); and graduated measuring cylinders (see ISO 4788). The procedures are not recommended for testing of volumetric instruments with capacities below 0,1 ml such as micro-glassware.ISO 4787:2010 does not deal specifically with pyknometers as specified in ISO 3507. However, the procedures specified for the determination of volume of glassware can, for the most part, also be followed for the calibration of pyknometers.
