IS 6100:1984 relates to Sodium Tripolyphosphate, Anhydrous, Technical, delineating its specifications, sampling protocols, and examination techniques. This standard is essential for sodium tripolyphosphate's use as a detergent builder and deflocculant.

Sodium phosphate, particularly in its polyphosphate form, showcases remarkable versatility. Among the significant sodium phosphate compounds, sodium tripolyphosphate emerges as a recent addition to this essential chemical family.

Sodium tripolyphosphate is manufactured through the neutralization of phosphoric acid, generated via either wet or thermal processes. It comprises one mole of monosodium orthophosphate and two moles of disodium orthophosphate, meticulously blended to ensure optimal product yield. The substance must predominantly comprise sodium tripolyphosphate and should manifest as a white, homogeneous, free-flowing powder, devoid of any visible impurities.

Upon testing as per the specified method, the substance must conform to the standards outlined.

TESTS

The subsequent test must be conducted for Sodium Tripolyphosphate Anhydrous.

PACKING AND MARKING

Packing and marking procedures must align with IS 6100:1984 guidelines. The substance should be securely packaged in clean and intact paper bags, with each bag appropriately labeled with the required information as per the standard.

Each bag must bear the Standard Mark (ISI Mark) if the material meets all specified requirements. To utilize the standard mark (ISI Mark), manufacturers are required to obtain a BIS license from the Bureau of Indian Standards. This license is granted following a thorough assessment of manufacturing infrastructure, quality control measures, testing capabilities, and production processes.
