ГОСТ Р 8.857-2013

State system for ensuring the uniformity of measurements. pH-meters. Verification procedure

Государственная система обеспечения единства измерений. рН-метры. Методика поверки

Status: Effective - Introduced for the first time. IUS 8-2014

This standard establishes methods and means of primary and periodic verification of pH meters, consisting of electrodes, temperature sensors and measuring transducers (PIs), and designed to measure the activity index of hydrogen ions (pH) and the temperature of controlled aqueous solutions. Passed for type approval, out of production, out of repair and in service in the manner prescribed by the rules of metrology [1]

Настоящий стандарт устанавливает методы и средства первичной и периодической поверок рН - метров, состоящих из электродов, датчиков температуры и измерительных преобразователей (ИП), и предназначенных для измерений показателя активности ионов водорода (рН) и температуры контролируемых водных растворов.Поверке подвергают рН-метры, прошедшие испытания в целях утверждения типа, выпускаемые из производства, выходящие из ремонта и находящиеся в эксплуатации в порядке, предусмотренном правилами по метрологии [1]
