New Test Methods for measurement of re-breathing in infant bedding materials

1. Scope

Evaluation of multiple methods for measurement of re-breathing, seeking consensus on reliable test methods.


SIDS; re-breathing; carbon dioxide; suffocation


Re-breathing carbon dioxide is a recognized fatal hazard to infants. Measurement of re-breathing is more complex than measurement of airflow or firmness, requiring a mechanical breathing model, carbon dioxide gas, and a carbon dioxide analyzer. Less complex methodologies have been published and may be an alternative to the CO2 + analyzer method. Measurements of airflow and firmness can help identify SOME hazardous materials and constructions, but measurement of re-breathing can identify out ALL hazardous products.

The title and scope are in draft form and are under development within this ASTM Committee.
