SUBJECT Naturion Ioniser NA50 Performance of Ozone Emission CLIENT Serumi International Private Limited 36 Armenian Street #02-02 Singapore 179934 Attn: Mr Sean Gan PY TEST DATE 16 Mar 2015 DESCRIPTION OF IONISER The photograph and specifications of Naturion Ioniser NA50 were listed in Annex A. METHOD OF TEST The Naturion Ioniser NA50 was tested in a 1 m 3 chamber (Annex B). The Naturion Ioniser NA50 was fixed on a Fan. The Fan generates wind through a short channel. The Naturion Ioniser NA50 was then fixed on the end of channel. An ozone sensor was installed in front of the Naturion Ioniser NA50 with a distance of 10 cm to monitor ozone concentration. Ozone concentration was recorded by every 1 minute during a 30 minutes period. Laboratory: TÜV SÜD PSB Pte. Ltd.

SUMMARY The NEA guidelines and SS554 were referred to evaluate ozone emission from Naturion Ioniser NA50. Ozone was not detected at the detection limit of 0.01 ppm during Naturion Ioniser NA50 s 30 minutes operation time at a distance of 10 cm away from the ioniser. The NA50 ozone emission meets the ozone accepted limit of less than 0.05 ppm in NEA guidelines for Good Indoor Air Quality in Office Premises" and ozone accepted limit of less than 0.1 ppm in Table 2 of Singapore Standard SS554:2009 Indoor Air Quality for Air conditioned Buildings.
