High and low temperature cycle test

As we all know, in the natural environment, temperature and humidity are two inseparable natural factors. Different regions have different temperature and humidity effects due to different geographical locations.

To achieve such a certain temperature test, it is necessary to rely on the high and low temperature cycle test.

High and low temperature cycle test is one of the product environmental reliability test.

Basically all products are stored in a certain temperature environment, or work operation.

In some environments, the temperature changes constantly, when high and low.

For example, day and night in some areas with large temperature differences.

Or the product in the process of transportation, storage, operation repeatedly in and out of the high temperature area, low temperature area.

Such a high and low temperature environment may reach above 70°C degrees or even higher at high temperature, and the low temperature may reach below-20°C degrees or even lower.

Electronic products generally, after the temperature test, if they can meet the following basic requirements, the product is considered to meet the high and low temperature requirements.

(1) No damage, deformation and other defects of the product surface. If coated surface, there should be no coating peeling, foaming or discoloration.

(2) For plastic parts, there is no crack, foaming and deformation on the surface.

(3) Rubber products without aging, bonding, softening and cracking phenomenon.

(4) There is no flow in the welding part of the product parts.

(5) The performance data and structural functions of the product meet the requirements of technical conditions and should not appear any other defects that hinder the normal work of the product.

High and low temperature experiment is used for both large or large electronic, automobile, rubber, plastic and communication equipment or large products for temperature and humidity environment test.

So as to judge the product reliability and stability of energy and other parameters are qualified.

High and low temperature test test will provide you to predict and improve the quality and reliability of the product!

Electric blankets must obtain CE certification to export to the EU

  CE certification is a mandatory certification mark for products entering the European market indicating that the product meets the basic requirements of the EU's Technical Coordination and Standardization New Method Directive. The CE certification access model adopted by the EU market for electric blankets includes the following five parts: Low voltage instruction (LVD 2014/35/EU): Ensure the safe use of electric blankets under low voltage. Electromagnetic Compatibility Directive (EMCD 2014/30/EU): to ensure that the electric blanket does not produce electromagnetic interference to other electronic devices when used. Energy efficiency Directive (ErP): requires electric blankets to meet certain energy efficiency standards to reduce energy consumption. Directive to limit the use of certain harmful components in electronic and electrical products (RoHS): limits the use of certain harmful substances, such as lead, mercury, hexavalent chromium, etc., in electric blankets. Electronic a...

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...
