ČSN EN ISO 11990-2   (192012) Optika a optické přístroje - Lasery a laserová zařízení - Stanovení odolnosti tracheální kanyly vůči účinkům laserového záření - Část 2: Manžeta tracheální kanyly

Anotace textu normy ČSN EN ISO 11990-2   (192012)

This part of ISO 11990 specifies a method of testing the continuous wave (cw) resistance of the cuff regions of tracheal tubes designed to resist ignition by a laser. Other components of the system, such as the inflation system and shaft (as defined in ISO 11990 1), are outside the scope of this part of ISO 11990.

NOTE 1: The method for testing the laser resistance of the tracheal tube shaft is in the scope of ISO 11990 1.

The specified test method can be used to measure and describe the properties of materials, products or assemblies in response to heat and flame under controlled laboratory conditions. It does not describe or appraise the fire hazard or fire risk of materials, products or assemblies under actual clinical use conditions. However, the results of this test method may be used as an element of a fire risk assessment which takes into account all of the factors that are pertinent to an assessment of the hazard of a particular end use.
