SPECIAL PROVISIONS
1
Object of approval and scope of application
(1) The object of National Technical Approval is factory-produced tanks as described in Annex 1,
with a capacity of 1000 l, 1500 l and 2500 l, which consist of an approximately cubic inner tank
(storage tank) produced by rotational moulding and a surrounding outer tank, which is equipped
with two horizontal, tubular tie straps of galvanised steel and functions as a collecting tank, which
together form a tank combination of polyethylene (PE-LLD), hereinafter referred to as a tank – with
integrated collecting tank.
(2) Part of the inner tank presses against the inside wall of the outer tank under hydrostatic liquid
pressure, and therefore also provides support under normal operating conditions, this support
being limited to static load without exposure to the contained liquids.
(3) The peripheral units for filling, ventilation, protection against overfilling, draining, monitoring the
fill level and leakage, and other items of equipment are positioned on top of the inner tank.
(4) The tanks may be placed in rooms inside buildings and outdoors, but not in areas subject to a
risk of explosion classed as Zones 0 and 1. In high-water or flood areas, the tanks must be
positioned where they cannot be reached by the water.
(5) When installed outdoors, the upper part of the tank, which contains the connections for
equipment and accessories, is fitted with a rotationally moulded hinged lid of polyethylene
(PE-LLD), which is secured to the outer tank.
(6) At a maximum temperature of 40 °C of the stored liquids, the tanks may be used for the
stationary, non-pressurised storage of the following liquids that are hazardous to water, provided
that stored liquids are not mixed:
1. Heating oil grade EL to DIN 51603-1
2. Heating oil DIN 51603-6 grade EL A Bio 5 to Bio 15 to DIN SPEC 51603-6
DIN EN 14214
3. Diesel fuel to DIN EN 590
4. Fatty acid methyl esters to DIN EN 14214
5. Lubricating, hydraulic and heat transfer oils (grade Q), with or without additives,
flashpoint > 55 °C
6. Lubricating, hydraulic and heat transfer oils (grade Q), used, flashpoint > 55 °C; operator must
be able to prove origin and flashpoint
7. Pure urea solution 32.5 % as NO
density of 1.15 g/cm
(7) National Technical Approval is granted without prejudice to inspection or approval provisos
from other areas of law.
