As per IS 5557:2004, protective rubber boots are categorized into three types. The standard pertains to the following industrial protective rubber boot classifications:

Each variety is divided into two types:

• Type 1 - Non-oil resistant

• Type 2 - Oil resistant

The boots should be crafted with rubber material and equipped with fabric lining. It's essential that the rubber components of the boots possess nonporous and uniform characteristics, meeting the physical standards detailed in IS 5557:2004. The prescribed minimum thickness for Type 1 and Type 2 boots across different parts and components must also comply with the standards outlined. Additionally, the manufacturing of boots must utilize either the vulcanized process, molded process, or a combination of both.

TESTS

The subsequent test must be conducted for industrial and protective rubber knee and ankle boots.

• Size, Thickness Test

• Composite Strength

• Leakage Resistance

• Consolidation Test

• Performance Test

• Height Of Boots

• Tensile Test

• Performance Test

A well-maintained laboratory is necessary for conducting the various tests outlined in the standard, following the specified methods.

All required markings, including information specified by the Indian standard, must be applied to the insole or leg lining fabric. Additionally, boots may feature the ISI certification mark, and packaging and labeling must adhere to the appropriate standards. To utilize the standard mark (ISI Mark), the manufacturer must acquire a BIS license from the Bureau of Indian Standards. This license is granted following a comprehensive assessment of manufacturing infrastructure, quality control and testing capabilities, and production processes.
