maximum allowable working pressure

maximum allowable working pressure means the maximum working pressure that is specified by the manufacturer in the plans and specifications accepted and registered by the provincial authorities and that is set out in the record referred to in section 5.18. (pression de fonctionnement maximale autorisée)

maximum temperature

maximum temperature means the maximum temperature that is specified by the manufacturer in the plans and specifications accepted and registered by the provincial authorities and that is set out in the record referred to in section 5.18. (température maximale)

NDT technician

NDT technician means a person who performs nondestructive testing and who is certified to carry out such testing. (technicien END)
