Introduction

Analysis of the core content of the standard

This standard specifies a complete method system for determining the diameter distribution of electronic-grade E-glass fiber yarn using the laser 3D topography measurement microscope system. The main technical features include:

Technical elements	TVCTES 1030-2020	ASTM D578:2005	Innovation points
Measurement principle	Laser confocal 3D synthetic imaging	Two-dimensional measurement with optical microscope	Three-dimensional measurement with 50nm accuracy on the Z axis
Magnification	≥1000 times	≥400 times	Resolution improved by 2.5 times
Data processing	Image segmentation/merging algorithm	Manual measurement	Improved degree of automation

Key technology implementation points

1. Sample preparation specifications

Use ceramic scissors to cut 3 cm long yarn samples, and clamp them with double glass slides to ensure the verticality of the fibers (see Figure 1). When fixing with tape, keep the top of the yarn protruding 1-2 mm.

2. 3D imaging process

200x lensPreliminary positioning of fiber groups
400x lensCalibrate the central field of view
1000x lensRecord the extreme elevation point (Z-axis limit position)
3D image synthesis eliminates focal plane differences

Fiber diameter statistical algorithm

The standard proposes a statistical model based on normal distribution:

Single fiber diameter calculation:d = (R×L)/h_pixel, where R is the actual length of the scale (μm) and L is the number of short-diameter pixels

Uniformity determination:Coefficient of variation CV =

Introduction of electric stage to realize automatic stitching of multiple fields of view
Clear the digital processing flow of colloid particle interference (Figure 2→Figure 3)
Establish software criteria for fiber adhesion segmentation (Figure 4-Figure 6)

Implementation suggestions

Take 5 cross-section samples for every 60m of yarn to ensure representativeness
Regularly calibrate the XYZ axis accuracy of the microscope (≤50nm)
Preferably use automatic image analysis software to reduce human errors
The test environment is strictly controlled within the atmospheric conditions specified in GB/T 6529
