News: CCC for Ex

CCC certification for Ex products in China

(Last update: 15 October 2019)

Per October 01, 2019, new CCC certification rules for Ex-products sold in China will apply, replacing the current National Production License System (shortened as NPLS). There will be a one year transition period.

Per October 01, 2020, most Ex-products sold in China have to be covered by a new CCC Ex-product certification.

This new regulation applies to all products listed in the existing catalogue from the Production Licence procedure. Some products, like LED lighting apparatus, are not included in this catalogue and therefore exempt (for now) from this new regulation.

Most important change:
These new CCC Ex-certification rules will apply to the Ex-production quality of manufacturing done inside China, AND to the Ex-production quality of manufacturing done outside China.
Having a valid ATEX QAN and/or IECEx QAR is not sufficient!

Basic Rules
The basic principles and requirements of the new certification rules are stated in document
CNCA-C23-01:2019 - Compulsory Certification Rules - Explosion protected electrical Equipment (also called ‘CCC Ex’).

The CNCA-C23-01:2019 regulation requires that all Ex-products listed in the product catalogue, irrespective of the place of manufacture, must be assessed in a three-step CCC certification process:
1. The Type Test (Ex-product evaluation, testing and certification)
2. The Initial Factory Inspection
3. The Post-Certification Supervision (Surveillance audits and Re-Assessment audits)

Regarding point 1. The Type Test (Ex-product evaluation, testing and certification)
This process remains largely unchanged in practice, because the basis of the product evaluation and testing will be the Chinese GB certification standards, which are derived from the IEC certification standards for Ex-products, as is the case at present. The CCC Ex- certificate is valid for 5 years and recertification must be initiated minimum 90 days before the expiry date.

Important note: A valid CNEx product certificate can be used to cover this Type Test.

Regarding point 2 and point 3:
Until now, manufacturers that sold Ex-products inside China, but manufactured these Ex- products outside China, were exempt from CCC and thus exempt from steps 2 and 3, if they had a correct, valid QAN/QAR covering their Ex-product manufacturing quality.
Under the new CCC rules, the full 3-step CCC certification process will apply also to them.

Important change:
The frequency of the Post-Certification Supervisions is NOT in line with IECEx/ATEX production quality audit rules. Instead, the frequency of the Surveillance and Re-assessment audits depends on the Classification of the Company (see below).

Classification of the Company

A company is classified as a Type A, B, C, D company, based on the status of the quality system of the manufacturer. This classification is done by the CCC Ex Certification Body chosen by the manufacturer. The rules for this Classification of the Company are stated in document
CNCA-00C-003-2014 - Compulsory Certification Implementation Rules - Manufacturer Classification Management, Selection and Determination of Certification Mode.

Auditing frequency
The mandatory frequency of Surveillance Audits and Re-Assessment audits is linked to the Company Classification.

The relation between Quality Management System, Classification and audit frequency, is as follows:
Quality System Audit Frequency
A                          Once every two years
B                          Once a year
C                          Once a year
D                          Twice a year

Depending on the Classification, the audit covers the following inspection content:

Classification Inspection Content
A                       Supervision inspection, or sample tests or inspection at the production site
B                      Supervision inspection and/or sample tests or inspection at the production site
C                      Supervision inspection and sample tests or inspection at the production site
D                      Supervision inspection and sample tests or inspection at the production site

The rules for the production quality at the manufacturer’s facilities are covered in the document
CNCA-00C-005-2014 - Compulsory Certification Implementation Rules – Factory Quality Assurance Ability Requirements.

The rules for the assessment of the production quality at the manufacturer’s facilities are covered in the document CNCA-00C-006-2014 - Compulsory Certification Implementation Rules – General Requirements for Factory Inspection and Auditing.

Important change:
The audits at the manufacturing location can only be done by CCC Ex-auditors that are appointed by the Chinese CCC Ex-Certification Bodies and that are recognised by the CCAA. The IECEx ExTL and ExCB CQST in Nanyang is also CCC Ex-Certification Body.

The sample tests or inspections at the production site should cover the Ex-types and product types of the product to be certified. If deemed necessary, the selected samples can be tested/inspected at the designated testing laboratory.

Notes
The above stated GB standards are derived from the IEC certification standards for Ex-products. The Gb standard versions are in most cases technically equivalent to (the previous version of -) the current IEC standards.

An Ex-product that is certified to the current IEC standards for Ex-products, will in most cases also comply with the technical requirements of the GB standards for Ex-products.

In the same way as an ATEX certificate is mandatory for Ex-products marketed and sold in Europe, a Chinese Ex-certificate is mandatory for Ex-products marketed and sold in China.

Important change: The Ex-product must be marked with:
