Petroleum product colorimetric solution No. 1-25 complies with SH/T 0168-92

Petroleum product colorimetric solution1-25number （ 25 bottle/Set)

comply withSH/T 0168-92standard1~25Oil product colorimetric solution（25 bottle/Set)This isA specialized standard reference reagent for determining the color of lubricating oil, kerosene, diesel and other products in petrochemical laboratories.

Core Standards and Principles

1. execution standard：SH/T 0168-92《The method for determining the chromaticity of petroleum products is to load the sample into a specified colorimetric tube and compare it with the standard color grade（1~25Perform visual color comparison with the corresponding color number (the larger the number, the darker the color), and use the matching color number as the sample chromaticity result.

2. Applicable subjectsVarious types of lubricating oils, kerosene, diesel and other petroleum products with light to medium color codes; Dark samples can be diluted with kerosene that meets the requirements according to the standard for measurement.

Common specifications and parameters

25mlX25bottle/set 50mL×25bottle/setalso have1000mLThe medium is a water-based standard system; Validity period6 Months (stored in a sealed, dark, and cool place, and strictly prohibited from being used for arbitration testing after expiration); Packaged in brown opaque bottles

Testing requires supporting instruments

1. Supporting instruments: Need to be equipped with a standard colorimeter and a dedicated colorimetric tube (inner diameter)32.5~33.4mm, high120~130mmColorless flat bottomed glass tube), the light source needs to be controlled within2750±50KThe standard conditions.

2. Operation and Quality Control：

• The colorimetric tube must be clean and scratch free, avoiding oil stains and fingerprints;

• Strictly control the height of the liquid layer and the angle of the light source according to the standards;

• Regularly cross compare with the same batch of standard solution to prevent color liquid deterioration or instrument drift;

• When the color is between two, report the darker color according to the standard.

Additional notes

SH/T 0168-92andGB/T 6540TheASTM D1500There is a corresponding color code conversion relationshipCan meet the mutual recognition of results under different standard systems; This analog color solution is a routine laboratory reagent with no strong corrosiveness, but it needs to be stored according to chemical management regulations to avoid contact with children.
