"Кратность воздухообмена в помещениях должна быть 3-4 кр/ч."
"Ventilation rate on the premises should be 3-4 ....... /per hour?"
Source: federal regulations for the paint manufacturing industry.
I'm assuming "ч" stands for "hour", but not sure what is meant by "кр" - any ideas would be much appreciated. Thanks in advance!
