Frequently asked questions about the Liquid-tight Facility Declaration

What is AS 6700?

The Verklaring Vloedichte Voorziening (Liquid-tight Facility Declaration) is issued after an independent inspection on compliance with the requirements. A national assessment scheme is used for the inspection:

The inspection of your liquid-tight facility or floor based on the AS SIKB 6700 Inspection of Soil Protection Facilities guidelines can be done through four protocols. The inspection agency, Normec QS in this case, will determine for each facility which protocol is best suited for inspection. On the basis of the chosen protocol, the liquid-tight facility is described in order to receive the Liquid-tight Facility Declaration.

What is CUR/PBV Recommendation 44?

The CUR/PBV Recommendation 44 is the predecessor of the current AS 6700 scheme. Since 1 July 2013 it is no longer permitted to issue a Liquid-tight Facility Declaration based on CUR/PBV Recommendation 44. The AS 6700 scheme is the successor to CUR/PBV Recommendation 44 (fourth revised edition) and the PBV Declaration.

What is the difference between AS 6700 and CUR/PBV Recommendation 44?

The transition to the AS 6700 scheme, is particularly relevant to the period of validity of your Liquid-tight Facility Declaration. The period of validity as described in your environmental permit (formerly environmental permit) is leading. Previously, verification of compliance with laws and regulations was an integral part of the inspection. This is no longer the case with the AS 6700 scheme. In the Activities Decree Internet Module you can consult regulations relevant to you.

How do you receive the Liquid-tight Facility Declaration?

After placing the order, the inspection is scheduled. Our inspector will perform the inspection according to Protocol 6701, 6702 or 6703, depending on the object. He will take photographs and produce inspection drawings.

After the inspection has been completed, the report is drawn up. If it can be demonstrated that the requirements have been met, we will issue the Liquid-tight Facility Declaration.

What should you do after receiving the statement?

As an attachment to the Declaration you will receive an Internal Company Checklist. This list can be used to perform the mandatory annual in-company inspection (BIC). By performing an internal audit you ensure the validity of the Declaration. If desired, we can also perform the annual internal audit for you.

How long is a Liquid-tight Facility Declaration valid?

This declaration is valid for 6 years.
