GB/T 22906.4-2008 "Testing of cores - Part 4: Determination of dimensions" specifies the methods for determining the dimensions of cores, applicable to various types of cores. It defines the measuring tools and operational steps for core length, wall thickness, and internal and external diameters. The standard requires measuring multiple points and taking the average value to ensure the accuracy and repeatability of dimensional measurements, providing a basis for dimensional compatibility in the production and application of cores.
