1. Introduction to GS certification

GS certification is based on the German Product Safety Act (SGS) and is a voluntary certification that is tested in accordance with the European Union's unified standard EN or the German industrial standard DIN. It is a German safety certification mark recognized in the European market. As a symbol of product safety and quality reliability, GS has been widely recognized by consumers in Germany and the European Union. The quality and safety of products with the GS logo exceed the level required by law. The GS mark can get a higher degree of recognition than the CE mark, because the GS certificate is issued by a third-party testing agency with certain qualifications.

The GS mark indicates that the safety of the product has been tested by a credible independent institution. Although the GS mark is not a legal requirement, it does enable manufacturers to be bound by strict German (European) product safety laws when a product malfunctions and causes an accident. Therefore, the GS mark is a powerful marketing tool that can enhance customers' confidence and desire to buy. Although GS is a German standard, it is recognized by most European countries. And while meeting the GS certification, the product will also meet the requirements of the European Community's CE mark. Unlike CE, there is no legal requirement for the GS mark, but because safety awareness has penetrated into ordinary consumers, an electrical appliance with the GS mark may be more competitive than ordinary products in the market.


The difference between GS certification and CE certification

GS certification CE certification
Voluntary certification non-comp Ülsory Compulsory Certification CompÜlsory
Applicable to German safety regulations for testing GS Applicable to European Standards (EN) for testing
Test content: safety standard Test content: EMC instruction + LVD instruction
Tested by an independent third party authorized by the German government and issued a GS mark certificate CE can be declared by itself under the premise of having complete technical documents (including test reports)
annual fee is required no annual fee
Annual factory inspection is mandatory No factory inspection required
The GS mark is issued by the authorized testing unit, with high credibility and market acceptance The factory's self-declaration of product compliance has low credibility and market acceptance

6. Required information

1. Fill out the application form

2. Sign the master agreement

3. Information required for safety assessment

The CB certificate and report of the product can be provided, which must include the European group difference. Or provide the information required for safety assessment (instruction manual, parts list, circuit diagram and layout, structure diagram, specifications of transformers and other components, etc. )

10. If the product category is applicable, the evaluation report of DMF and EMF shall be provided.


7. Certification process

1. First meeting: Through the first meeting, the testing agency or agency will explain the specific procedures of certification and relevant standards to the applicant's product engineer, and provide the required document form.

2. Application: The applicant submits the documents that meet the requirements. For electrical products, it is necessary to submit the general assembly drawing of the product, the electrical schematic diagram, the list of materials, the product use or installation manual, and the difference between the series and models.

3. Technical meeting: After the testing agency has checked the applicant's documents and materials, it will arrange a technical meeting with the applicant's technical staff.

4. Sample test: The test will be carried out in accordance with the applicable standards, and can be carried out in the manufacturer's laboratory or any laboratory of the inspection agency stationed in each country.

5. Factory inspection: GS certification requires inspection of safety-related procedures on the production site.

6. Issue GS certificate.


8. Certification cycle and validity period

The GS certification cycle depends on whether the product needs to be modified or the speed at which the manufacturer submits the required product documentation.

The GS certificate is valid within 5 years after it is promulgated by the certification body. During the validity period, the factory will review it once a year. After 5 years, the product test needs to be re-tested to obtain the GS certification.
