What does GB/T 47086-2026 mean for fiber diameter testing?
GB/T 47086-2026 took effect on August 1, 2026. It specifies a digital optical scanning method for the diameter and distribution of reinforcing fibers and microfibrous wool. TANVINT is one of its drafting organizations. Material scope, preparation, calibration, and statistical conditions still require confirmation.
Status and scope
The standard was published on January 28, 2026 and took effect on August 1. Its full text defines the scope and method requirements. A product citing the standard does not demonstrate conformity for every material or preparation condition.
Drafting participation and equipment capability
TANVINT is one of the drafting organizations. This role does not constitute equipment certification or automatically replace every manual microscopy method.
Procurement and acceptance conditions
Agree on materials, diameter range, reference samples, calibration curves, effective fiber counts, rescanning the same slide, and independent preparation tests. Specify timing boundaries, report fields, and decision rules in the acceptance plan.
