Analyser specifications. 4.2.1. General In addition to the linearity requirements defined for each analyser in paragraph 3., the compliance of analyser types with the specifications laid down in paragraphs 4.2.2. to 4.2.8. shall be demonstrated by the analyser manufacturer. Analysers shall have a measuring range and response time appropriate to measure with adequate accuracy the concentrations of the exhaust gas components at the applicable emissions standard under transient and steady state conditions. The sensitivity of the analysers to shocks, vibration, aging, variability in temperature and air pressure as well as electromagnetic interferences and other impacts related to vehicle and analyser operation shall be limited as far as possible.
