Evaluation of Formaldehyde Reference Material for Chamber Emission Testing
Dustin G. Poppendieck, Na Li, Wenhao Chen
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.
