Concrete air entraining agent/air entraining agent EN934-2 EU CE certification - Nanjing Smart provides EU announcement laboratory to issue EN934-2 certificate
Air entraining agent, also known as air entraining agent, is a hydrophobic surfactant that dissolves in water and is added to concrete mixtures. During the mixing process, it can generate a large number of tiny bubbles. Air entraining agents can improve the flowability, cohesiveness, and water retention of concrete mixtures, enhance the flowability of concrete, and introduce a large number of uniformly distributed, closed, and stable micro bubbles as additives during the mixing process of concrete mixtures. The air entraining agent/air entraining agent used in concrete needs to apply for CE certification in accordance with the requirements of the EU CPR regulation, based on the coordinated standard EN 934-2:2009+A1:2012, and operated according to System 2+. System 2+requires on-site factory audits of products by qualified and competent notified bodies, followed by ongoing factory audits. For specific EU CE certification of air entraining agents/air entraining agents for concrete, please consult Nanjing Smart Company at +86 25 -8658 3475.

…
4) Does this product require an annual factory audit?
Yes.
5) How long is the certification cycle approximately?
This product requires factory audit and initial type testing, which usually takes about 3-4 months if everything goes smoothly.
6) What is the difference between a notified body and a non notified body?
The notified body is registered on the official website of the European Union and can be found on the authorization list of all directives. Its qualifications have been reviewed and recognized by the European Union, and the review mainly includes the evaluation and qualification of experimental equipment and related engineers. The institution is issued with an independent announcement number (the announcement number is a 4-digit number). The relevant test reports and certificates issued are widely recognized and accepted in all member states of the European Union.
Non notified organizations do not have laboratories and personnel that meet the above requirements. The certificate is not recognized in the European Union.
7) Which institutions can issue CE certificates for concrete air entraining agents/air entraining agents?
It must be an EU notified body, authorized by building materials regulations and EN 934-2:2009+A1:2012 standards.
8) When is the mandatory execution time for EN 934-2:2009+A1:2012?
Starting from July 1, 2013, concrete air entraining agents/air entraining agents entering the European Union must have CE certification, otherwise the products will be confiscated or fined.
9) How to choose a CE certification agency for concrete air entraining agents/air entraining agents?
We should choose a laboratory with the EU NB number published by Europa, and it needs to have both EN 934-2:2009+A1:2012 standard testing and certification capabilities.
10) What if the test fails?
Which test of the product did not pass, which additional test needs to be supplemented, and a new sample needs to be sent.
11) What documents are required for factory audit?
If the factory already has ISO9001, the audit will be much simpler; If there is no IS09001, it does not affect, but more materials and documents need to be reviewed. Manage and control products based on the ISO9001 system.
12) What is the validity period of the CE certificate for air entraining agents/air entraining agents used in concrete?
As long as regulations and standards remain unchanged, the factory maintains annual factory audits, and the product itself remains unchanged, the certificate remains valid.
