ASTM E287 test results verify if a graduated buret is within tolerable permissible limits for calibration and delivery. Consistency over multiple test cycles is a major indicator of compliance. A buret that provides volumes with errors within the specified limits is compliant with ASTM E287. Where discrepancies are outside tolerances, the buret is not appropriate for laboratory use, as small errors interfere with titration accuracy.

Materials Commonly Tested with ASTM E287
ASTM E287 burets are used to make accurate measurements of the volumes of aqueous solutions, acids, and bases, and neutralization reactions in titrations. They can also be used for reagent standardization and quantitative chemical analysis in pharmaceutical, food, and water laboratory testing. The resistance of borosilicate glass to corrosive chemicals makes the burets suitable for a broad spectrum of laboratory applications.
Applications of ASTM E287 in Industry
The specification finds widespread applications in quality control, environmental water testing, food and beverage chemistry, petrochemical laboratories, and educational research. Industries that rely on titration, such as water treatment plants and pharmaceutical formulation units, benefit from the accuracy and recurrence ensured by E287.
Safety and Best Practices in ASTM E287
ASTM E287 emphasizes proper handling to break down and prevent contamination. Users should avoid sudden temperature changes, the buret should be handled vertically, and they should check the stopcocks to ensure they are not too tight before use. Proper cleaning is recommended with non-abrasive agents to prevent graduation. The calibration must be regularly verified to maintain compliance with the specification.
Importance of ASTM E287
The value of ASTM E287 is in its guarantee of accuracy and dependability in volumetric measurements that are essential in quantitative chemical analysis. By providing dimensional and performance standards, it reduces measurement errors, improves reproducibility of results, and promotes international consistency in laboratory practices. This makes ASTM E287 an essential component in driving scientific research, industrial quality control, and regulatory compliance.
