design freezeThe design freeze completes the design – the design has been examined and approved by the customer. Only then the purchasing process may commence. In order to optimize/save project time, the design freeze may also take place in partial sections (for individual systems/plants/machines or assemblies).
The following features/criteria will be examined:
  • system/plant/machine or assembly group functionality
  • mountability/assembly
  • operability/usability + ergonomics
  • service accessibility + spare parts
  • safety
The design freeze is an essential milestone, which will be elaborated and executed in a most detailed and conscientious manner by both esmo AG and their customers. Any design changes and follow-up costs occurring subsequent to the design freeze will be separately invoiced to the customer.

FATfactory acceptance test ::: The FAT is a functional test of the system/plant/machine at esmo AG together with the customer. The objective is the early detection of critical faults in the system/plant/machine prior to delivery. The successfully passed FAT will be the prerequisite for the delivery release of the system/plant/machine, and the subsequent issuance of the third partial invoice.
The detailed functional scope of this test will be precisely defined in advance upon order placement – it will furthermore depend on the general testing and inspection possibilities of the system/plant/machine at esmo AG.

OEEoverall equipment effectiveness ::: The OEE indicator – combining parameter availability, performance and quality – will constitute the basis for the acceptance of the system/plant/machine. The following chart depicts the calculation of the OEE:

overall equipment effectiveness

Performance Efficiency
The term "performance efficiency" is defined as the ratio between the theoretical output and the quantity actually produced, including bad/reject parts. The theoretical output will be calculated by multiplying the declared or stated power of the system/plant/machine by its actual operating time.

Quality Factor
The term "quality factor" is defined as the ratio between the good products and all manufactured products

Note:
The system/plant/machine shall have satisfied all quality criteria of the products to be manufactured prior to the test. Any system/plant/machine, manufacturing inferior quality products, may not be tested.

SATsite acceptance test ::: The SAT is a functional test of the system/plant/machine at the customer site after assembly/installation and commissioning. It should show and prove the proper installation and functionality of all safety devices. Additionally, the system/plant/machine must have already fulfilled all defined customer safety check specifications and further requirements. The control program is available and the system/plant/machine is ready for operation.
The system/plant/machine shall prove and meet all performance data and reliability requirements in a defined endurance test during SAT. All operators and service staff are trained.
After passing the SAT, the system/plant/machine may be used for production. Effective the date/time of the successfully passed SAT, the warranty period will commence, and the area of responsibility for the system/plant/machine will be transferred to the customer.
The detailed functional scope of this test will be precisely defined in advance upon order placement. After successfully passing the SAT, the system/plant/machine may be used for production – all system/plant/machine-related documentation will be submitted/handed over to the customer:
  • user/operating manuals
  • technical data
  • code words/passwords
