Last January the Spanish
Association for Standardization and Certification (AENOR), in collaboration
with the technology center specialized in materials LABEIN and the Scientific
and Technological Institute of Navarra, conducted the necessary tests for this
certification, such as a complete visit to the company's facilities.
Upon receipt of the results and noted the quality system implemented for
development of manufacture of the chambers, AENOR certifies that the product
" PLASTICS ACCESS CHAMBERS FOR ELECTRICAL USE " is consistent with
the standard UNE 20100422005 to "Plastic chambers designed for electrical
use."

The trials were conducted to:
- Resistance to aging and humidity,
- Mechanical strength (impact test, compression test)
- Resistance to heat.
- Dielectric strength and insulation resistance.
- Impact resistance
This certification is in addition to others such as Telefónica,
France Telecom, Iberdrola, Endesa, Madrid
Cityhall..., consolidating the Hidrostank chambers as a quality assurance for
the implementation on site.
This is possible due to the bet of the Hidrostank direction of the
company for a policy based on the quality of their products.
Hidrostank Access Chamber
The polypropylene reinforced modular chambers are a very interesting
alternative to traditional systems(conchete, brick) as they present the
following characteristics:
• They are self-resistant (up to 70x70 cm)
• It is innovative
• A product of quality: customized inlets
• Easy and quick installation manual handling without machinery.
• Versatile: height adaptable
• Economical: Save time, effort, money and maintenance
There have been many projects both urbanization and Civil Works /
Infrastructure who have trusted in our self-resistant chambers, the most
significant: Airports in Madrid and Barcelona, Radial 4 Madrid, Mediterranean,
Cantabrian, Douro Motorways, EXPO Zaragoza 2008 ...
