The main consideration in MTBF calculation is the failure rate of each component in the product.However,due to the significant differences in failure rates of devices under different environments and usage conditions,these factors must be considered when calculating reliability indicators.And these factors are almost impossible to calculate manually,but with the help of software such as MTBFcal and its vast parameter library,MTBF values can be easily obtained.

During the use of speakers,they may be affected by different environments(some installed outdoors,some carried around,some installed on ships,etc.),such as wind,rain,humidity,vibration and falling,salt spray erosion,etc;In order to confirm that the product can work properly in these environments,both national and industry standards require the product to simulate some testing items in environmental methods.

Specifically,MTBF testing refers to the average working time between two adjacent failures,also known as the mean time between failures.It is only applicable to repairable products.At the same time,it is also stipulated that the ratio of the cumulative working time to the number of failures during the total usage phase of the product is MTBF.

Which method should be chosen for MTBF testing?

1.Based on the stage:design stage-MTBF estimation method validation or mass production stage-MTBF testing method or MTBF acceleration method

2.Whether to stamp with CNAS seal,using MTBF test method for stamping

3.Based on the testing cost,the MTBF acceleration method has a lower testing cost

4.Based on the sample information,when the sample is valuable and there are few samples available,use MTBF acceleration method

MTBF testing application process:

1.Customers fill in the service application form:fill in the product name,model,company name,and address

2.Quotation:Evaluate based on the testing conditions or standards required by the product and customer.

3.Sample:Specific situation

4.Testing conditions:Provide testing conditions and standards.If they cannot be provided,our company can recommend them.

5.Report confirmation:After the testing is completed,provide the draft report to the client for confirmation.If there are no issues,the original version will be issued.

6.Closing:Payment
