Introduction

Analysis of the key points of the standard revision

Compared with GB/T19113-2003 standard, the new version mainly optimizes:

Improvement dimensions	2003 version	2022 version	Upgrade benefits
Grading indicators	Dry shell quantity single core	Dry shell quantity/cocoon layer quantity/cocoon layer rate/total cocoon quantity multiple systems	Diversified evaluation dimensions
Technical equipment	Basic instruments	Introduction>Cocoon X-ray Machine	Non-destructive Inspection
Moisture Control	Simple Moisture Content	Moisture Content Gradient Correction	More Accurate Moisture Damage Prevention

Core Evaluation: 11 basic indicators (1 to 11) + five-dimensional correction indicators (upgrade/downgrade mechanism)

Grading Selection: Selecting dry shell weight ≥10.6g is equivalent to downgrading (e.g. fresh cocoon cocoon layer weight ≥13.6g corresponds to grade 1)
Correction Mechanism: Example: When the uniformity is <60%, it must be reduced by 2 levels; when the moisture content of the cocoon layer is >22%, it must be reduced by 3 levels.

Core parameters: Light wavelength 520±10nm | Irradiation intensity ≤300lux

Steps	Operation points	Error control
Light transmission calibration	Preset white balance adjustment test ring 3 times	ΔL≤2%
Pupae determination	Resolution characteristic spectrum comparison	Misclassification rate ≤0.8%
