Gardner Color: Liquid Standard (No. 8)

Gardner Liquid Color Standard (No. 8) for Accurate Visual Comparison

Color Measurement

Color measurement is important in many industries such as petroleum, chemical and pharmaceutical where product quality and consistency is critical. The Gardner Color Scale is a widely accepted standard for measuring the color of transparent liquids from light yellow to dark brown.

This scale is used to evaluate the color quality of products to meet industry and customer standards. Originally based on visual comparison to existing color standards, color measurement has evolved with technology to include objective measurement methods. While the human eye was once the primary tool for color evaluation, reproducible distinction of colors is now achieved through measurement under defined conditions to ensure accuracy and consistency.

Gardner Liquid Color Standard (No. 8 on Gardner Scale)

Gardner Liquid Color Standards are used in the ASTM C40 and AASHTO T 21 test methods for the determination of organic impurities in aggregates. They are an alternative to the Organic Impurities Test Set. Individual standards are available in 5 Gardner colors listed in the standard test method. The liquid is sealed in 0.47x4.6in (11.9x116mm) Dia.xH glass tubes marked with the Gardner number and packaged in a protective case. Shelf life is 5 years.

Gardner Liquid Color Standard (No. 8) is a color reference standard. The Gardner scale is used to measure color in various substances, oils, varnishes and chemicals. The scale has evolved from visual comparison to precise measurement using spectrophotometry as per ASTM standards, where color is determined accurately.

Gardner Color Scale

The Gardner Color Scale is a well known system to measure the light yellow of the color of transparent liquids like oils, varnishes and resins in glass filters. This scale has 18 steps from light yellow (1) to dark brown (18) to measure and classify color. The Gardner Color Scale is used in industries like petroleum, chemical and pharmaceutical where color quality is critical for quality control.

By providing a standardized way of color evaluation the Gardner Color Scale ensures products meet industry and customer standards. The Gardner Color Scale also shows a strong correlation with other color measurement systems, ensuring comprehensive color evaluation across different standards.
