Cold and hot shock test chamber

 Cold and hot shock test chamber, also known as high and low temperature shock test chamber or temperature shock test machine, is a kind of test equipment specially used for testing electrical, electronic products, original devices and their materials in the environment of storage, transportation, use in the temperature of the adaptability of the test equipment.

Its main function is to test the ability of the samples to tolerate temperature changes by conducting rapid cooling and heating in a predetermined temperature range.

The working principle of the cold and hot shock test chamber is mainly based on the physical laws of heat conduction and heat exchange.

By controlling high temperature and low temperature, the airflow circulation system is used to realize rapid temperature change.

In the high temperature area, the temperature is increased by the heating element (such as heating resistance or heating wire), while in the low temperature area, the temperature is reduced to the desired low temperature value by the refrigerator or refrigerant.

During the test, the product is placed in the working area, and the flow direction of hot air or cold air is quickly switched through the sample handling system, so that the product quickly experiences temperature changes.

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 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

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 and sc
