EN50155:2017 Standard test item requirements:

1. safety test: voltage resistance test and insulation resistance test, divided into hot and humid insulation resistance and pressure and insulation resistance and pressure at room temperature.

(Mandatory requirements)

2. emc test: electrostatic discharge, conduction harassment, radiation harassment test, radio frequency electromagnetic field, surge test, conduction immunity test, radiation immunity, pulse group test.

(Mandatory requirements)

3. performance test: power supply overvoltage, voltage change, power off test power supply fluctuation test, technical specifications requirements, etc.

(Mandatory requirements)

4. environmental adaptability test: high temperature test, low temperature test, alternating humidity test, mechanical impact test, long life vibration, functional vibration.

(Mandatory requirements)

5. Other items: IP protection grade, enhanced screening, low-temperature storage test, salt spray test, rapid temperature change, etc. (optional)

EN50155 Routine test content: appearance inspection, performance test, low temperature test, high temperature test, power supply fluctuation, power off test, insulation resistance and insulation withstand voltage, impact vibration test and so on.

In general, the type test report reflects whether the standard requirements are met. The 1-4 type items are the required items, and the fifth item can be selected according to the actual needs of the product or the customer.

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...
