In latex gloves, powder can bind to latex proteins, making them airborne and increasing the risk of allergic reactions for both patients and staff. The Two Testing Procedures
Despite being originally approved in 2006 (the "-06" suffix), this standard remains a cornerstone reference for quality control labs, regulatory compliance (FDA, CE, TGA), and procurement specifications in hospitals worldwide.

The standard outlines two distinct methodologies based on the glove type: Procedure I: Used for gloves labeled as powder-free
Unlike colorimetry, amperometric titration measures the electric current generated when chlorine reacts with a titrant. For low ionic strength, ASTM D6124-06 prescribes specific modifications: In latex gloves, powder can bind to latex
For labs routinely analyzing low-ionic-strength matrices, this method belongs in your standard operating procedures.
Technicians measure the "ash content"—the inorganic filler left behind—to calculate exactly how much powder was on the glove. 🧤 Why This Matters to You For formal compliance testing, please obtain the complete
However, even "powder-free" gloves are not truly free of powder. The manufacturing process (chlorination, polymer coating, or other treatments) reduces powder but often leaves residual traces. provides the forensic tool to measure that residue, ensuring it falls below acceptable thresholds (typically < 2 mg per glove for powder-free claims).
For healthcare facilities, purchasing gloves that meet this standard reduces the risk of liability associated with patient complications from residual contaminants.
If a glove brand receives complaints of “white residue” or “dusty gloves,” the complaint investigation will often invoke ASTM D6124-06 to quantify the residue and determine if it exceeds labeled claims.
It allows for an "apples-to-apples" comparison between different brands and materials, whether they are nitrile, latex, or vinyl . Conclusion
