The standard method ASTM C693 measures the density of glass. Measuring the thickness of the glass is very important as any change in the density can lead to undesired results. Density measurement also validates the purity of the raw material. Density is obtained in kg/m³ or g/cm³.
Scope:
Finding the density of glass by ASTM C693 is essential as it provides information about the mass and volume and shows how much pressure will be applied to the glass to displace it. Density data provide information about the purity of raw materials of glass and is different for various composites. It has several applications in development, construction, research, and production.
Test Procedure:
The mass of the given glass sample is measured on an electric balance, and the reading is recorded. The same sample is weighed two more times to reduce the experimental error as the average of the three values is taken as the mass value. To measure the volume of the given glass sample, it is carefully immersed in a solution/water, and the increase in the volume of the solution is noted. The initial volume is subtracted from the final volume, and the reading is used as the value of the glass volume.
Specimen Size :
The sample size can vary from mg to kg.
Data:
The formula to measure the density of glass; Density = mass/volume ρ=m/V… (1)
For Mass:
| Mass of the glass (g)Reading 1 | Mass of the glass (g)Reading 2 | Mass of the glass(g)Reading 3 | Average (g) |
| 0.80 | 0.80 | 0.80 | 0.80 |
For Volume
| The volume of Water in cm3 | The volume of Water in cm3 | |
| Without Glass cm3 | With glass cm3 | |
| 6.0 | 6.4 | 6.4-6.0=0.4 |
By putting values in equation (1), the value of density ρ=0.80/0.4= 2g/cm3

The ASTM D2674 is a standard test method for the analysis of sulfochromate etches solution used in the surface preparation of aluminum. The ASTM D2674 standard specifies a method for determining the efficacy of an etchant used to prepare the surface of aluminum alloys for subsequent adhesive bonding.
An immunological method for quantization of Hevea Natural Rubber (HNRL) proteins using rabbit anti-HNRL serum. Rabbits immunized with HNRL proteins react to the majority of the proteins present, and their sera have the capability to detect most if not all the proteins in HNRL.
