Introduction to ASTM E1
The term Beckmann thermometer is frequently used to refer to enclosed-scale thermometers. Within a wider temperature range, they can measure minor temperature variations of up to 6°C. MaTestLab is one of the best testing service providers, with the best network of testing laboratories in the USA to carry out ASTM E1 tests for our clients. If the thermometers haven’t been instantly tested with standard instruments, they aren’t acceptable for measuring temperatures in Celsius or Kelvin.
ASTM E1 Test Method
| Inscription | All figures, letters, immersion lines, and graduation lines must be permanently attached, appropriately colored, and clearly defined. |
| Test for permanency of pigment | After three hours at 260°C in the oven, the thermometer’s scale piece is taken out and allowed to cool. The thermometer is examined for variations in appearance between the tested and untested sections; rejection causes include burning out, loosening, chalking, or fading of the color. |
| Bulb stability test | After five minutes of heating, a thermometer is cooled to either 20°C or 50°C. A reference point is used to calculate the reading. After a full day of heating, cooling, and recalculating, the thermometer is used. A shift in the reference reading signifies the quality of the bulb glass. |
ASTM E1 Test Specimens
| Specimen Detail | Liquid-in-glass thermometers are the specimens used in ASTM E1. |
| Specimen Size | The stem needs to have an enamel back and a simple front and be constructed of appropriate thermometer tubing. The bulb requires glass with a viscosity of at least 1014.6 poises at 490 °C (914 °F) and at least 1013.4 poises at 520 °C (968 °F). |
ASTM E1 Test Result
To sum up, ASTM E1 covers liquid-in-glass thermometers graduated in either degrees Celsius or degrees Fahrenheit. These thermometers are widely used and accepted in procedures supervised by the many ASTM technical committees.
