Shenzhen United Testing Technology Co., Ltd

  Intelligent switch   is   the unit that uses the combination and programming of the control board and electronic components to realize the circuit intelligent switch control. Switch control, also known as BANG-BANG control, is simple and easy to implement, so it is adopted in the control of many household appliances and lighting lamps. Intelligent switch belongs to AV / IT products, entering the US market needs to apply for FCC-ID certification. Contact us if you need. www.uni-lab.hk/

  CPC (Children's Product Certificate) certification of toy bricks should be provide in Amazon USA, which includes ASTM-F963 and CPSIA.

Abrasi ve   resistance testing is the ability of the material to resist mechanical wear. Under the grinding condition of a certain load weight, the grinding of unit area per unit time. E xpressed by the wear amount of the sample, it is equal to the difference between the pre-grinding mass of the sample and the post-grinding mass divided by the wear area, by the reciprocal of the wear rate or wear degree of the material under the specified friction conditions. Effect of a brasi ve   resistance test ing : Wear and tear is a common phenomenon in the industrial field and daily life. Many reasons for this phenomenon , physical, chemical and mechanical, mainly abrasive wear, adhesive wear (bonding), fatigue wear (pitting), corrosion wear, which is an important reason for the loss of materials and energy. Wear problem covers a wide range.   Material wear resistance as an engineering research, its purpose is the product manufacturing and product production process of wear problems and study ho

  FCC-ID is mandatory for active wireless transmission equipment. After passing the test, it will be issued by CCB institutions and registered on the FCC official website. The common test criteria are as follows:

  FCC SDOC For non-wireless transmission products, the test criteria are as follows:

  It is well known that Britain has left the EU. From January 1,2021, products requiring CE identification in the EU market and UKCA identification and manufacturer conformity statement when entering the UK market. UKCA mark, like CE mark, the manufacturer is responsible for ensuring that the product meets the standards stipulated by the decree and making self-declaration in accordance with the prescribed procedures, before making the corresponding mark on the product. Why cooling leafless fans exported to the UK need UKCA: The UKCA certification indicates that the product has met the safety requirements of the UK Directive; it is a corporate commitment to the consumer that increases their trust in the product. After handling UKCA, it can not be investigated by market supervision agencies, not be detained by the customs, and not be reported by peers. Note: UKCA is not suitable for products entering Northern Ireland. The UKCA logo can not be used in the Northern Ireland market alone. Ad
