ECMA-328 3rd Edition / June 2007 Determination of Chemical Emission Rates from Electronic Equipment Ecma International Rue du Rhne 114 CH-1204 Geneva T/F: +41 22 849 6000/01 www.ecma-international.org IW ECMA-328.doc 12.09.2007 17:31:00 Determination of Chemical Emission Rates from Electronic Equipment Standard ECMA-328 3rd Edition / June 2007 . - 5 - Introduction Globally, governmental agencies, academic institutions, environmental organizations and manufacturers have developed methods to determine chemical emissions from electronic equipment. These attempts however, resulted in a range of tests from which the results are not necessarily comparable, either qualitatively or quantitatively. Following the publications of the 1st edition of ECMA-328 and the “Test method for the determination of emissions from Hard Copy Devices” (RAL-UZ 122), experts from the BAM and Ecma have collaborated to harmonise methods to determine the chemical emission rates from ICT 2. Tested in a controlled ETC as specified in Clause 7; 3. Sampled/monitored and calculated as specified in Clause 8; 4. Reported as specified in Clause 9. For EUT using consumables, determinations according to additional requirements identified by “RAL-UZ 122 Option” herein conform to the RAL-UZ 122 Option. 3 Normative references CIE 15:2004 Commission Internationale de lEclairage Colorimetry, 3rd edition ECMA-74 Measurement of Airborne Noise emitted by Information Technology and Telecommunications Equipment (2005) ISO 554:1976 Standard atmospheres for conditioning and/or testing - Specifications ISO 13655:1996 Graphic technology Spectral Measurements and colorimetric computation for graphic arts images - 2 - ISO 16000-3:2001 Indoor air Part 3: Determination of formaldehyde and other carbonyl compounds Active sampling method ISO 16000-6:2004 Indoor air Part 6: Determination of volatile organic compounds in indoor and chamber air by active sampling on TENAX TA sorbent, thermal desorption and gas chromatography using MS/FID ISO-16000-9:2006 Indoor air Part 9: Determination of the emission of volatile organic compounds from building products and furnishing Emission test chamber method ISO 16017-1:2000 Indoor ambient and workplace air - Sampling and analysis of volatile organic compounds by sorbent tube / thermal desorption / capillary gas chromatography Part 1: Pumped sampling EN 55013:2001 Sound and Television Broadcast Receivers and associated equipment Radio disturbance characteristics Limits and methods for measurement RAL-UZ 122 Test method for the determination of emissions from Hard Copy Devices according to RAL-UZ 122 (Annex 2) 4 Definitions For the purpose of this Standard the following definitions apply. 4.1 Air exchange rate (n) Ratio (n) of the volume of clean air brought into the ETC per hour m3/h to the unloaded ETC volume m3. 4.2 Air velocity The air speed m/s measured in the unloaded ETC. 4.3 Analyte VOC, carbonyl compounds, ozone and particulate matter. 4.4 Consumables Toner, ink, paper and ribbon. 4.5 Emission Test Chamber (ETC) Enclosure with controlled operational parameters for testing analyte mass emitted from EUT. 4.6 Equipment Under Test (EUT) Functional and complete, including consumables and accessories if applicable, ICT or CE equipment, from which chemical emission rates are determined as specified herein. 4.7 Loading factor Ratio of the EUT volume to the volume of the unloaded ETC. 4.8 Hard Copy Devices Class of EUT using Consumables that includes printers, (Photo)copiers and Multi Functional Devices (MFD). 4.9 Operating phase Phase in which the EUT is performing its intended functions. 4.10 Particulate matter Airborne particles. - 3 - 4.11 Pre-operating phase Phase in which the EUT is connected to an electrical supply, which may include warming-up and energy saving modes; before the EUT is able to enter the operating phase. 4.12 Post-operating phase Phase following the operating Phase.
