A company data issued from a guideline study (closed cup) was available, but since the purity was not mentionned, it has been quoted as a reliability 4. This value, together with the other values found in different handbooks were used in a weight of evidence approach, and the flash point range retained was 26 -30°C, leading to the conclusion that Cyclopentanone is a flammable liquid.
