Part such as register, clock, reservoir, input and output periphery etc. are examined, detected.Current software test uses white-box testing side
Formula is primarily present following shortcoming：
1st, because different household appliances may use different controllers, identical household appliances may use different controls
Device processed, same controller are it is also possible that write software with different language, therefore the repeatability of software evaluation is poor, often
Secondary assessment all equivalent to customized, wastes substantial amounts of time, man power and material, this is that enterprise and testing agency are all difficult to bear
's.
In addition, the controller of Some Enterprises is development ＆ production abroad, for evaluation process, if software security is tested
White-box testing all is used, generally requires to arrange software developer abroad to be tested, testing cost is very high.
2nd, white-box testing requires that enterprise provides core source program code and core data, could allow testing staff to source program
Enter Mobile state and static check is tested and examines whether related measure software works.And this way may be to enterprise due to presence
Industry brings the potential risk that kernel software and technology are divulged a secret, and allows enterprise very to worry and worry, so that enterprise and detection machine
It is difficult to coordinate between structure.

Diversified combination, its program function and hardware mechanism brought close, also vary, it is contemplated that the component of controller
Working condition, such as register, clock, reservoir, input and output periphery whether can break down, it may occur that what failure.Cause
This analysis to software, to set and check be a highly difficult and complicated job.This is accomplished by the system engineer, hard of specialty
Part engineer and software engineer, even if but it is professional again, for being examined with artificial mode after all
Look into, cannot guarantee that all softwares all meet the requirements of the standard, the measure method provided is all very appropriate, suitable, effective.
4th, the standard that household electrical appliances software evaluation is related to is more and complicated, including electric, electronics, software, both including the whole of household electrical appliances
Machine safety standard, also including part-subassemble standard；Should the universal standard requirement, also to consider particular criteria requirement.So multi-standard
In, the overwhelming majority only requires no method, this test mode used to inspection personnel in checking process and test knot
The judgement of fruit causes certain difficulty.Different inspection personnel may also can be caused, different understandings are had, can be caused different
Result of determination, may bring unnecessary trouble to enterprise.
