UKCA (United Kingdom Conformity Assessed) is a new UK product conformity assessment mark, implemented from January 1, 2021, aimed at ensuring that products comply with UK safety, health, and environmental requirements. The UKCA mark replaces the EU CE mark previously implemented in the UK, as the UK government decided to adopt an independent product conformity assessment system after Brexit. Therefore, electronic and electrical products entering the UK market need to pass standard testing under UK regulations, obtain UKCA certification, and be labeled with the UKCA mark to replace the use of the EU CE mark in the UK market.

The UK UKCA testing program for children's clothing may include the following:

1. Fiber content detection: Check the percentage of various fibers in clothing to ensure they comply with label or advertising claims.

2. Color fastness test to water: Test the color retention ability of clothing after washing to ensure that it is not easily faded under normal washing conditions.

3. Detection of color fastness to sweat stains: Simulate human sweating and test the color retention ability of clothing under the action of sweat.

4. Testing of color fastness to friction: Simulate the actual use of clothing using a friction testing machine to test the color retention ability of clothing.


The UK UKCA certification process generally includes the following steps:

1. Determine the applicable product range: Firstly, it is necessary to confirm whether the product needs to undergo UKCA certification. UKCA certification is applicable to some products that involve safety, health, or environmental protection.

2. Preparation of documents and test reports: Before submitting the application to the certification body, necessary documents and test reports need to be prepared to prove that the product meets relevant standards and requirements.

3. Select a certification agency and submit an application: Based on the product type, select a qualified certification agency for certification review and submit a UKCA certification application.

4. Document review and on-site inspection or sample testing: The certification agency will review the documents and may require on-site inspection or sample testing to verify that the product meets the requirements.

5. Certification review and obtaining certification: The certification agency will comprehensively consider all aspects to evaluate whether the product meets the UKCA certification requirements. If it passes the review, UKCA certification will be issued.
