Ventilation ducting is an important part of keeping indoor air clean and fresh. It helps maintain proper airflow in homes, offices, and industries, while also preventing dust and contaminants from spreading. Since these ducts are used regularly, quality, safety, and durability are very important.
In accordance with BIS Quality Control Order (QCO), manufacturers are supposed to get BIS Certification prior to launching of these products in Indian markets. This involves product testing and factory inspection by BIS for meeting Indian Standards prescribed therein. Upon successful examination of the manufacturers and their products, BIS certification is granted and they are authorized to display the ISI Mark on their products, indicating that the standards as laid down in IS 3768:1996 have been complied with.
IS 3768:1996 outlines the specifications of vinyl coated, flexible and semi-rigid ventilation ducting that is used for ventilation systems. Several qualities need to be considered to provide longevity, flexibility, mechanical strength and the ability to withstand the effects of the environment. According to BIS, the ventilation ducting is -
