Bis Certification for Industrial and Protective Rubber Knee and Ankle Boots The Bureau of Indian Standards (BIS) has laid down specifications under IS 5557:2004 for industrial and protective rubber knee and ankle boots. This standard ensures that such boots, commonly used in industrial environments and hazardous working conditions, provide adequate protection to workers’ feet and lower legs. These boots are designed to withstand exposure to water, chemicals, and rough surfaces, making them suitable for sectors like construction, sanitation, and mining. Manufacturers producing these rubber boots are now required to obtain BIS certification before marketing them in India. The certification ensures that the boots comply with the defined safety and quality norms. Furthermore, every certified pair must carry the ISI Mark, representing the assurance of quality and adherence to BIS standards.
