This page aims to provide 
      the reader with the reasons why our 
		service 
      sometimes requires that extinguishers undergo discharge testing. 
      
      As mentioned in the service page, 
      our BS EN ISO 9001:2015 certification certifies that we undertake the
      service to the standards laid down in
      BS 5306-3 - the main standard 
      applicable to the servicing of portable fire extinguishers. 
      In addition to the ‘basic service’ which is generally undertaken annually, this
      Standard also sets out a schedule 
      for the ‘extended service’, 
      generally performed at five yearly intervals (click
      here for more complete 
      details of the periods applicable to each category of extinguisher). 
      In addition to enabling a rigorous check on whether the extinguisher 
      will operate, the discharge test also facilitates a detailed examination 
      of the internal and other usually hidden parts of the extinguisher which 
      cannot normally be undertaken during the normal
      ‘basic service’. 
      
      In order to keep the cost to our customers to a minimum, we sometimes 
      operate a service exchange program. In these cases, when extinguishers 
      require discharge-testing, they will generally be swapped for comparable 
      units that have already undergone the testing and refilling process. In 
      this way, the expense of a re-visit is avoided.
