Scope
NB/T 10545-2021 is the English-translated version of 矿用光纤寻障仪.
NB/T 10545-2021 is the Chinese energy industry standard for fiber optic obstacle finders used in mines, instruments that measure the length of an optical fiber and locate fault points along it.
It defines terms including the length measurement error, the gap between the length reported by the instrument and the real fiber length. The standard sets the product model, technical requirements, test methods and inspection rules, along with marking, packaging, transport and storage.
Battery-powered units draw on the nickel-metal hydride battery standard among its references. It was issued on 7 January 2021 and has applied since 1 April 2021.
