IS 12345:1988 pertains to Vinyl Acetate Monomer. This Indian Standard was adopted by the Bureau of Indian Standards on February 25, 1988, subsequent to the approval of the draft by the Organic Chemicals (Miscellaneous) Sectional Committee under the Petroleum, Coal, and Related Products Division Council.

This standard outlines the specifications, sampling procedures, and testing methods for vinyl acetate monomer. Vinyl acetate monomers are derived through the reaction of acetic acid with either acetylene or ethylene, facilitated by a catalyst.

The substance should be a clear, colorless liquid, devoid of any suspended particles. The presence of an appropriate stabilizer is permissible. Additionally, compliance with the standard's specifications is imperative.

TESTS

The subsequent test must be conducted for Vinyl Acetate Monomer.

• Reagents Test

• Acidity test

• Vinyl Acetate Content Test

• Hydroquinone Content

• Diphenyl Amine Content

• Polymer Content Test

The substance will be packaged in mild steel drums or other appropriate containers, subject to agreement between the buyer and seller. Each container should be securely sealed and labeled with the required information as outlined in the standard. Additionally, the container may feature the Standard Mark (ISI Mark).

In compliance with this standard, products may undergo certification under the regulations outlined in the Bureau of Indian Standards Act, 2016, along with its accompanying Rules and Regulations. Manufacturers are required to acquire a BIS license from the Bureau of Indian Standards to utilize the standard mark (ISI Mark), which is granted following a comprehensive evaluation of manufacturing infrastructure, quality control measures, testing capabilities, and production processes.
