Product Overview
The ASTM A305 color standard solution is a precision-formulated reference material designed to meet the stringent requirements of ASTM D1500 and related testing protocols. This solution provides a consistent benchmark for color comparison in petroleum products, lubricants, and chemical samples, ensuring reproducibility across experiments. The high-purity composition eliminates variability caused by impurities, making it ideal for laboratories requiring strict adherence to international standards. Each batch undergoes rigorous quality control to guarantee conformity with ASTM specifications, with traceable certification provided for compliance documentation. The liquid form allows for easy handling and dispensing, while the 500 ml pack size offers sufficient volume for repeated testing without frequent replenishment. Compatible with standard colorimeters and visual comparison methods, this solution maintains stability under typical laboratory storage conditions. The analytical grade designation confirms its suitability for critical applications where color accuracy directly impacts product classification or quality assessment.
FAQs
1. How does this solution compare to other ASTM color standards?
This solution specifically matches ASTM D1500’s A305 reference point, which represents a darker hue than A15 or A25 but lighter than A40. It’s calibrated to provide precise intermediate color values for petroleum product grading.
2. What is the recommended storage temperature range?
Store between 15-25°C in the original container, away from direct sunlight. Temperature fluctuations outside this range may temporarily affect color consistency until the solution re-equilibrates.
3. Can this be used with automated color measurement systems?
Yes, the solution is compatible with both visual comparison methods and automated spectrophotometers or colorimeters that follow ASTM D1500 protocols.
4. What is the typical shelf life under proper storage?
When stored unopened in original packaging, the solution maintains its certified color values for 24 months from the date of manufacture. Opened bottles should be used within 12 months.
5. Are recalibration certificates provided with each batch?
Each production batch includes a certificate of analysis traceable to NIST standards, verifying compliance with ASTM D1500 color specifications at the time of manufacture.
