ISO CERTIFICATION?

• The critical parameters measured are time and temperature.
  
  
• TTI's can be formulated according to the stability criteria of the product to be monitored.
  
  
• The central active portion develops color (from the start point) in response to exposure to a specific time and temperature or to an equivalent time-temperature history.
  
  
• TTI's repond to the integral of the temperature history following the Arrhenius relationship, which is equivalent to the response to the mean kinetic temperature.
  
  
• TTI's are used to indicate that the product has not been exposed to an excessive temperature history as specified by the product's manufacturer.
  
  
• TTI's are self-adhering and can be applied directly to the primary or secondary unit container.
