EK1-ITB 2000:2009AG1-EK1176-08 rev 1Bases for GS-mark tests of IT Equipment inCombination with Visual Display Units(Status as of January 01, 2009)The processing of test principles for the evaluation of visual display units occurred initially inGermany under management of the Administrative Legal Accident Insurance. With thereorganization of the Experience Exchange of GS Test Organizations, Exchange of ExperienceForum 1 (EK1) assumed this task in 1998.With the progress of European standardization, and with increasing experience in the assessmentof IT equipment in combination with visual display units, the test principles are being maintainedup to date.New display techniques, as PDA's, micro displays and beamers can be included. Therefore, thetest principles were provided with a new number, complemented with the date of the current stateof the discussions as a permanent document.These test principles comprise the requirements that are prerequisites for the safe and ergonomicdesign of the equipment. In addition, there are requirements for the workplace and the workplaceenvironment, which are to be considered by the user or operator, and therefore, are not subject tothese test principles.These test principles are to be used in the current version at the time of the investigation.Certificates that refer to earlier versions of this document remain basically valid within the frame ofthe usual period of validity of a GS Certificate, unless EK1 decides in exceptional cases due tourgent necessities differently.Disclaimer: This is a translation from the German original version to English. In the case of anyinconsistencies the German version is valid!Exchange of Experience Forum 1 (EK1) of GS Test Organizations, EK1-ITB 2000,Status as of January 01, 2009, rev. 1Editor: TÜV Rheinland Product Safety; E-mail: scheuer@de.tuv.com 1/17

Ifnecessary, he has to determine any special environmental conditions in theInstructions for Use. These declarations are to be considered during the test andare to be repeated in the certificate. In particular, restrictive declarations of themanufacturer in his product description must also be documented in the certificate.Information necessary for installation, startup procedure and safe use mustaccompany the product in writing (German language). Broader information may becontained on data storage devices (CD, floppy disk).The existing test principles are binding on all GS test- and certification bodies andare to be considered by market surveillance authorities in Germany too.If the requirements of the applicable standards are not specific, the EssentialRequirements of the Directives or the protection objectives of the Standards are tobe interpreted by the experts accordingly.Exchange of Experience Forum 1 (EK1) of GS Test Organizations, EK1-ITB 2000,Status as of January 01, 2009, rev. 1Editor: TÜV Rheinland Product Safety; E-mail: scheuer@de.tuv.com 3/17

The following items have to be considered:1. Measurement procedureUse a) or b):a) Electric test (IT device without supplied ear-/headphone)In deviation to EN 50332 a measurement of the output voltage with adjustment ofthe volume control to center position has to be made with and without equalizer.During the measurements the equalizer is adjusted to its neutral or center position(factory setting). In case the reading is ≤ 150 mV the instructions for use mustconsider a warning note to fulfill the requirements according to EK1-ITB 2000. Incase the reading is > 150 mV the requirements according to EK1-ITB 2000 arenot fulfilled.b) Acoustic test (IT device with supplied ear-/headphone)In case of a system (IT device with an ear-/headphone) the type of the ear-/headphone (manufacturer and model/type) has to be specified in the instructionsfor use. The requirements according to EN 50332-1 have to be fulfilled. Indeviation to EN 50332-1 the measurements shall be conducted with adjustment ofthe volume control to center position with and without equalizer. The instructionsfor use must contain a warning note.Informative: A measurement of the output voltage with adjustment of the volumecontrol and equalizer to maximum has to be carried out.2. Warning note (example)Excessive sound pressure from ear-/headphones can cause hearing damage/hearing loss.Adjustment of the volume control as well as the equalizer to other settings thanthe center position may increase the ear-/headphones output voltage andtherefore the sound pressure level.The use of factors influencing the ear-/headphones output other than thosespecified by the manufacturer (e.g. operating system, equalizer software,firmware, driver) may increase the ear-/headphones output voltage and thereforethe sound pressure level.The use of ear-/headphones other than those specified by the manufacturer maylead to heightened sound pressure level.Exchange of Experience Forum 1 (EK1) of GS Test Organizations, EK1-ITB 2000,Status as of January 01, 2009, rev. 1Editor: TÜV Rheinland Product Safety; E-mail: scheuer@de.tuv.com 16/17
