标准范围

ISO 8655-7:2005规定了活塞式容量仪测量误差的光度法和滴定法测定。这些测试适用于完整的系统，包括基本仪器和选择与仪器一起使用的所有部件，一次性或可重复使用，涉及交付测量过程。这些非重量测试方法可用于:作为供应商质量保证的辅助手段；作为用户的日常质量保证和日常校准；作为常规和维修后测试。ISO 8655-7:2005中描述的方法不适用于ISO 8655中规定的重量参考试验方法的替代方法-6，给出了唯一适合作为供应商声明或独立合格证明依据的方法。注1:ISO 8655-2至ISO 8655-5中规定了活塞式容积仪的计量要求，尤其是最大允许误差。注2:关于一致性声明和合格证书的一致性试验或型式试验，请参见ISO 8655-6中的重量分析参考试验方法。

ISO 8655-7:2005 specifies the photometric and titrimetric determination of errors of measurement of piston-operated volumetric apparatus. The tests are applicable to complete systems comprising the basic apparatus and all parts selected for use with the apparatus, disposable or reusable, involved in the measurement by delivery process.These non-gravimetric test methods can be applied: as aids to quality assurance by the supplier; as routine quality assurance and routine calibrations by the user; and as routine and post-repair testing.The methods described in ISO 8655-7:2005 are not applicable as alternatives to the gravimetric reference test methods specified in ISO 8655-6, which gives the only method suitable as a basis for supplier's declarations or independent certification of conformity.NOTE 1 Metrological requirements for piston-operated volumetric apparatus, especially maximum permissible errors, are specified in ISO 8655-2 to ISO 8655-5.NOTE 2 For conformity tests or type tests for declaration and certification of conformity, see the gravimetric reference test methods in ISO 8655-6.
