Abstract

Formaldehyde reference materials are being developed by the National Institute of Standards and Technology (NIST) for use in regulatory emission testing certification programs. Emission rates for a prototype formaldehyde reference material were determined using small-scale chamber experiments. The uncertainty associated with the average emission rate were deter-mined using a set of six reference material prototypes and measurement traceability to NIST primary standards. Overall, the 95 % confidence interval on the random (Type A) error plus the quantified systematic (Type B) error represents 4.9 % of the average emission rate. A four lab inter-comparison study was performed using the prototype reference material. Three of the labs measured similar emission rates, with a relative standard deviation of 3.2 %. It is not known why the fourth lab measured higher emission rates.
