Introduction
Flat panel display substrate glass is a key strategic material for the electronic information display industry. The quality of substrate glass is closely related to the resolution and transparency of the finished panel.
Brightness, thickness, weight, viewing angle and other indicators are closely related, representing the highest level in the field of global modern glass scale manufacturing.
As substrate glass continues to become higher definition, larger size, and ultra-thin, the quality requirements for display substrate glass are increasing year by year.
Appearance, length and width dimensions and deviations, thickness deviation, thickness difference, cutting angle deviation, positioning angle deviation, squareness, surface roughness, waviness, deterioration
Fire point, strain point, softening point, average linear thermal expansion coefficient, thermal conductivity, reheat linear shrinkage, specific heat capacity, density, stress, Young's modulus, shear
Modulus, Poisson's ratio, Vickers hardness, transmittance, refractive index, volume resistivity, dielectric constant and dielectric loss factor are the properties of flat panel display substrate glass.
These indicators will affect the product quality of flat panel display substrate glass, so it is necessary to establish the flat panel display substrate glass testing
Try method.
GB/T 45505 aims to provide test methods for various properties of flat panel display substrate glass and is intended to consist of 5 parts.
--- Part 1.Appearance and geometric dimensions. The purpose is to provide a test method for the appearance and geometric dimensions of flat panel display substrate glass.

4 Test methods
4.1 Density
4.1.1 Test principle
The density of a solid substance refers to its mass per unit volume at a specified temperature.
According to Archimedes' principle, the buoyancy of an object immersed in a medium is equal to the weight of the medium displaced by the object.
The buoyancy of the sample in a medium of known density can be used to calculate the density of the sample.
4.1.2 Test equipment
The test equipment includes.
---Analytical balance. 0g~200g, accuracy is 0.1mg;
---Suspension components. The suspension wire should be a metal wire with a diameter less than 0.2 mm and should be degreased or vacuum heated and cleaned;
The hanging wire, hanging basket or wire loop specimen support used in each test should be made of the same material;
