It looks like that a couple car manufactures have cheated on the measurements on their emission values. In commercial kitchen ventilation and in machine tool industries it is common practice not to do any measurements at all.
Ventilation engineers have frequently the problem, that efficiency values in specifications are not measured and validated in the field at all, after the ventilation systems are set up and put into operation. Even more worse makes this fact, that there are more and more low cost manufactures in the market, installing kitchen ventilation systems or air cleaner for machinery centers, not even having any kind of measurement devices (e.g. aerosol particle counters) to measure the separation efficiency of a commercial kitchen ventilation capture hood.
Also because of that, the new EN 16282 European standard, which will become effective shortly, claims in future the following: „The ventilation system shall be capable of separating odours, particles of fat and gaseous products from the exhaust air.“
This new EN 16282 standard will become effective in the following countries:
Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and United Kingdom.
