Test substances definition

Test substances means substances to be measured in air. Measured substances are Volatile Organic Compounds (VOCs) and the carbonyl compounds. VOCs range in volatility from n-C6 to n-C16 whose boiling point is in the range from (50 °C to 100 °C) to (240 °C to 260 °C). Carbonyl compounds include the aldehydes and ketones. In the test procedure the measured compounds are grouped by the term (VOC) and (carbonyl compounds) because each group currently requires two unique active sampling and analytical methods for measuring the test substances;
