Introduction of test methods and test process of sound box MTBF

The main consideration in the MTBF calculation is the inefficiency of each component in the product.

However, because the inefficiency of the devices will be very different under different environments and different use conditions, these factors must be considered when calculating the reliability indicators.

These factors can hardly be calculated manually, but with the help of software such as MTBFcal and its huge parameter library, you can easily get MTBF values.

During the use of the sound box, in different use environment (some installed outdoors, some carry, some on the ship, etc.), will be affected by different environments (some by wind and rain, some by vibration and fall, some by salt spray, etc.); in order to confirm that the product can work normally in these environments, the national standard and line standard require the product to simulate some test items in the environmental method.

Specifically, the MTBF test is the average working time between two adjacent failures, also known as the average failure interval.

It is the only one intended for serviceable products.

The ratio of the cumulative working time to the number of failures in the total use phase is also set as MTBF.

Which method do you choose to do the MTBF test?

1. According to the local stage: design stage - MTBF estimation method verification or mass production stage - MTBF test method or MTBF acceleration method

2. Whether to stamp CNAS seal with MTBF test method

3. According to the test cost, the MTBF acceleration method is a low test cost

4. According to the sample information, the MTBF acceleration method is used when the sample is more valuable and can provide less samples

MTBF test, as a typical test of environmental reliability test, our laboratory has many years of experience and methods, which can not only provide reliable solutions, but also provide high-quality testing services.

Shenzhen United Testing lab has rich experience and successful cases for MTBF testing. Contact us if you need.

C-Tick certification

C-tick authentication concept A/c-tick is A certification mark for Communications equipment issued by the Australian Communications Authority (ACA).Manufacturers and importers must follow the next step in using A-Tick: : 1. Product implementation ACAQ technical standard test 2. Register the use of A/C-Tick to ACA 3. Fill in the Declaration of Conformity Form and keep the product with the record C - tick certification In communication products or equipment with A/C - the identity of the Tick marks (label) 5, sales to consumers A - Tick only applies to communication products, electronic products, mostly apply C - Tick, but electronic products if the application is A - Tick, do not need to apply for the C - other Tick.Since November 2001, EMI in Australia/New Zealand has applied for a merger;If the product is to be sold in the two countries, the following documents must be in place before marketing, in case the authorities of the Australian Communications Authority or the Ministry of Ec...

IC certification

图片
IC is short for Industry Canada, a government agency that is responsible for the certification of electronic products entering the Canadian market.Its products are generally divided into: broadcast television equipment, information technology equipment, radio equipment, telecommunications equipment, engineering medical equipment, etc. Like the FCC in the u.s., IC currently only restricts electromagnetic interference. IC authentication method: There are two ways of Certification and Certification. IC ID: CN (Company Number, up to 6 digits) +UPN (Unique Product Number, up to 8 bits). ID application: 1. The address information of the representative of Canada must be provided. 2. The label shall include the following information (manufacturer name or trademark, model name, IC ID number). Related standards of IC certification: IC certification standards are basically in line with the FCC, and IC currently only restricts electromagnetic interference. Y-001 analog equipment: Industrial, Sc...

NOM certification

图片
The Normas Oficiales Mexicanas logo is a mandatory safety sign in Mexico to indicate that the product is in accordance with the associated NOM standard.The NOM logo applies to most products, including telecommunications and information technology equipment, household electrical appliances, lamps and other products that are potentially dangerous to health and safety.All products manufactured or imported in Mexico must comply with the relevant NOM standards  and product labeling requirements. The product of NOM compulsory certification is generally a voltage over 24 volts alternating current or direct current electrical products.It is mainly applicable to product safety, energy and thermal effect, installation, health and agriculture.The following products must obtain a NOM DE certification to allow access to the Mexican market: -- electronic or electrical products for use by families, offices and factories; -- computer LAN (LAN) equipment; -- lighting fixtures; -- tires, toys an...
