2. General characteristics taken into account for all products
These are physical or physico-chemical properties included in the specifications of several types of product, whatever their use.
2.1 Color
This characteristic applies to products that are said to be white, but which are in fact colored to varying degrees, from very pale yellow to dark brown.
There are two methods for estimating the color of petroleum products:

Saybolt color is expressed by a number related to the column height, ranging from +30 (practically colorless)...
