GB/T 46385.2-2025 Optical circuit boards—Part 2:Basic test and measurement procedures—General guidance for definition of measurement conditions for optical characteristics

Scope

This document describes a method for defining the measurement conditions of the optical characteristics of optical boards. This method uses a coding table to identify different key information of the measurement environment. The values extracted from the table are used to construct a measurement identification code, which itself can obtain sufficient measurement information to ensure that the consistency of independent measurement results is within an acceptable range. It also specifies preferred measurement conditions to minimize the uncertainty of independent measurement results.
