Standard classification system

The petroleum industry has not agreed on a standard classification system. Further, the classification of crude oil is of little importance in its production, with the exception that paraffinic crudes can precipitate wax...

The Council on Environmental Quafity, in consultation with the Administrator, the Secretary of Health and Human Services, the Secretary of Commerce, and the heads of other appropriate Federal departments or agencies, shall coordinate a study of the feasibility of establishing (1) a standard classification system for chemical substances and related substances, and (2) a standard means for storing and for obtaining rapid access to information respecting such substances. A report on such study shall be completed and submitted to Congress not later than 18 months after the effective date of enactment of this chapter.

First, the chemical name or synonym is found in the alphabetically sorted chemical index. The second step is to use the chemical class number, which appears to the left of the chemical name to search the selection recommendations tables. The master chemical resistance table is in numerical order by the chemical class. The final step is to find the chemical within the class listing and note the color-coded recommendations by barrier material. For example, to find the recommendations for protection from acetaldehyde, the user must first find the chemical class number in the Chemical Index section. We find the chemical acetaldehyde listed first in the chemical index in Section III. This listing shows a class number of 121. This is the chemical class for aldehydes (aliphatic and alicyclic) under the ASTM F-1186, Standard Classification System for Chemicals According to Functional Groups. This listing also... 

The chemical class numbers are shown in the first column and are used to find the recommended barriers in the Master Chemical Resistance Table of SELECTION RECOMMENDATIONS section.

There is no official standard classification system for different grades of nitrile rubber. Commonly the percent acrylonitrile (ACN) and the Mooney viscosity value (which crudely relates to average molecular weight by ASTM D1646) are used to classify an NBR. Even with this, however, it is very possible that two sources of NBR with the same ACN content and the same Mooney viscosity will still process very differently and impart quite different physical properties to a rubber compound. 

There is no standard classification system for ACM. Different grades of ACM polymers are produced from different combinations of alkyl acrylate monomers. 

There is no official standardized classification system for polychloroprene. However, DuPont Elastomers uses a system for their CR based on the following ... 

There is no standard classification system for CPE. However, Mooney viscosity (ASTM D1646) and percent chlorine are commonly used as characterizing tests.
