Classification of working conditions (EN ISO 15875)

The performance specifications for pipe-based systems complying with EN ISO 15875 are specified for a project with a 50-

year operational life.

• Working temperature (T

D): working temperature provided for the range of application, expressed in °C.

• Max. working temperature (T

MAX): the working temperature highest value, allowed only for a short period of time.

• Failure temperature (T

MAL): the highest temperature possible when control systems fail (the time allowed for this value is 100 h

over 50 years of uninterrupted operation).
