Methenamine Pill Testing Procedure

The methenamine tablet/pill burn test is mostly performed on flooring textiles such as carpets, rugs, and fabrics as standardized or adopted by ASTM D 2859, ISO 6925, 16 CFR 1630, 16 CFR 1631, CPSC FF-1-70, CPSC-FF-2-70, CGSB 4-GP-2, and other testing organizations around the world.  Flammability pill testing is also used to determine the flammability of various rubbers, plastics, and natural materials used by consumers.

A timed burning methenamine tablet test is performed by placing a tablet on the product and set fire.  The methenamine tablet will continue to flame in a controlled draft-free environment for an average burn time of 130 seconds. If, after the methenamine tablet has been consumed by the flames and the product itself continues to burn past a certain predetermined standard, that test will be deemed a “fail”.  If the product self extinguishes after the pill has been consumed and before the predetermined standard, that test will be deemed a “pass”.  This testing is referred to in the industry as the “pill test”.


Standards Laboratory Supply’s Methenamine Timed Burning Pills

Standards Laboratory Supply adheres strictly to the official standard in size, weight and chemical composition set forth by the Consumer Product Safety Commission publication (link) which states in the Code of Federal Regulations part 1630,  subpart A, 1630.4 (3) Standard igniting source. A methenamine tablet, flat, with a nominal heat of combustion value of 7180 calories/gram, a mass of 150 mg ±5 mg and a nominal diameter of 6mm. These tablets shall be stored in a desiccator over a desiccant for 24 hours prior to use. (Small quantities of absorbed water may cause the tablets to fracture when first ignited. If a major fracture occurs, any results from that test shall be ignored, and it shall be repeated.)

Our Methenamine pills are sealed 100 per bottle in tamper-resistant sleeves with cotton to prevent any breakage, a desiccant packet in every bottle, and a tight seal flip-top lid for fast and easy dispensing.

Our Helpful Contributions to Laboratories

We are the first to introduce two innovations in the market for methenamine timed burning pills.  As well as an industry-leading guarantee.

First our methenamine pills are the only methenamine timed burning pills in the market with a quality assurance desiccant packet in every bottle to help keep moisture away from the pills.  Since methenamine is a hygroscopic material it attracts moisture causing the methenamine pills to splinter and break when lighting.   This desiccant packet helps to keep the methenamine dry to prevent this type of breakage.   No more starting test over due to breakage.  No more wasted pills.  In the rare case you have a pill break don’t throw it away.  Because we also have an industry-leading money back or replacement guarantee.  Just remember to keep the desiccant packet in the bottle after opening.

Second we also introduced a tight sealing flip top lid for easier and faster dispensing of the methenamine.  We had the lab technician in mind when we developed this bottle.  Faster dispensing equal more pill tests completed.

Our Guarantee:  Even though we took the initiative to set industry-leading standards with methenamine to prevent any damaged pills there are rare cases.  So, in those rare cases, we have a guarantee that will replace any pills you might consider damaged.  Once you have completed your prior shipment and ready to reorder, simply place the pills in an empty bottle and mail them to us with your return address.  We will take care of the rest.  We value all our customers and intend to keep them first.

One more thing. We have also included free shipping to everywhere in the United States.
