3 Classification of Products

This Standard divides the solvent oil for paint and cleaning into 5 designations according to the distillation range of the product:

No.1 – Medium boiling point;

No.2 – High boiling point and low dry point;

No.3 – High boiling point;

No.4 – High boiling point and high flash point;

No.5 – Kerosene type.

The solvent oil with high boiling point is further divided into 3 types according to the aromatics content:

Ordinary type – aromatic content (volume fraction) 8%~22%;

Medium aromatic type – aromatic content (volume fraction) 2%~8%;

Low aromatic type – aromatic content (volume fraction) 0%~2%.

The medium boiling point and kerosene type are divided into two types, such as medium aromatic type and low aromatic type.

4 Product Identification

The identifications of solvent oil products for paint and cleaning are as follows:

+ +

For instance: No.3 ordinary type solvent oil for paint and cleaning.
