given as a reference. Author may change these subsections or add more requirements according 
to the corresponding product. 

This product is designed to be capable of operating 24 hours a day, 365 days a year under the 
specified environmental conditions defined in section 7.1 and 7.2. 

The reliability of this product shall be measured by MTBF (mean time between failures). It is the 
average time that this product is being used under its specific operating conditions before a 
failure occurs since last failure happened. It is measured in hours. 
 
The MTBF of this product is > ?????? hours. 
 
Note: The MTBF value is related to product design and manufacturing. It can be estimated based 
on the life accelerated tests. So when the product is in pre-production phase, the product life 
accelerated tests must be applied to ensure the required MTBF value is achievable.  

The MIL-STD-105E shall be used as the standard of making the random sampling inspections for 
product manufacturing. The minimum Acceptance Quality Level for this product is defined as 
following: 
 
Critical defects: no critical defect is acceptable 

Major defects: AQL  

Minor defects: AQL 

 
The author should define the AQL value based on the product characteristics. 
 
Defects Classification: 
 
Critical: likely to result in unsafe condition or contravene mandatory regulation (no critical defect is 
accepted). 
 
Major: reduces the usability of the product or is an obvious appearance defect. 
 
Minor: doesn’t reduce the usability of the product, but is a defect beyond the defined quality 
standard. 
 
The author can define these three types of defects in more detailed if it is necessary.
