The
manufacture and sale of glass aquaria
Insurance
Manufacturers of aquariums must hold Public and Product Liability
insurance of at least £1,000,000.
Installation
Each aquarium should be sold with full instructions for its
correct installation. These instructions should be prepared
by each manufacturer. (They should include the following:
weight when empty, weight when full of water-a table of weights
should be used- and a warning to the customer that they must
ensure that the structure upon which the aquarium is installed
must be capable of bearing this weight indefinitely, safe
procedures for transport and movement of aquaria, indications
of methods to ensure surface on which the aquarium is to be
installed is level).
Wholesalers and retailers selling aquaria should be conversant
with these instructions.
Manufacture
- The following glass types should NOT be used in aquarium
manufacture:
- decorative
- toughened glass without a frame
- Each piece of glass should be inspected for faults:
- prior to use
- and after cutting and cleaning and prior to gluing
Faulty glass should not be used. Faults causing the rejection
of glass would include imperfections in the sheet, chipping
and cracking or unevenness of edges.
- All glass edges exposed and unexposed, should be arrised
to a standard that enables them to pass the test described
for the Safety of Toys in EN7l: Part 1:1988 (BS 5665. Part
I 1989) Clause 4.18
- Each sheet of glass should be cleaned in a manner that
ensures no film remains, visible or invisible, that may
compromise the efficiency of the adhesive. This may be achieved
by:
- cleaning machinery using ammonia;
- hand cleaning using methylated spirits or appropriate
industrial cleaner.
- Aquarium manufacturers should ensure that the silicone
sealer used in construction is specifically recommended
for use in the manufacture of aquaria and is safe in use
(both for livestock and humans).
- Butt and corner joints should be used for aquaria of
18"x l2"x l2" and above. Fillet joints should only be used,
as the sole method of gluing, on smaller aquaria.
- It is recommended that aquaria should only be repaired
by their original manufacturer. Other repairs may invalidate
the manufacturers product warranty.
- This Code of Conduct applies to cubic aquaria up to a
length of 72" and a depth of 24".
- All aquaria designed to have a water depth greater than
17.5 ins. must he constructed of at least 6mm thick glass.
Where aquaria are 36 inches or greater in length they should
be made in 6mm glass when exceeding 15 inches in height
and in 10mm glass where the water depth exceeds 18 ins depth.
- Aquaria should be packaged to prevent damage in transit.
This should include at least enclosure of end faces of glass
with semi-rigid materials-capable of preventing accidental
damage of these surfaces under normal transit and handling
conditions- held firmly in place. In transit care should
be taken to ensure that exposed edges remain undamaged.
Testing
- Each manufacturer should submit the following aquaria
(or the closest in their range) for test:
- 8 x 12 x 12"
- 24 x 15 x 12"
- 36 x 15 x 12"
- 48 x 15 x 12"
plus one other aquaria selected from the manufacturers
range by the independent testing laboratory from a previously
supplied product list, specifying the glass thickness
used in construction.
If a manufacturer produces no aquaria below 24 x 15
x 12 then only the three other specified aquaria and that
selected by the testing laboratory need be submitted for
test.
- Annually after initial testing manufacturers should confirm
in writing that the specification of materials used and
design of aquaria manufactured has remained unaltered in
the previous 12 months. Permission to use the 'Approved
Product' logo will then be granted.
Where this is not the case i.e. when substantive alterations
have been made, a full re-test must be undertaken before
permission to use the 'Approved Product' logo will be
given.
- Aquaria to be tested should be selected from ordinary
stock and not specifically manufactured for the test.
- The laboratory will undertake the following procedures:
- Inspection
Glass to be inspected visually for flaws and imperfections.
Joints to be examined for compliance with Code of
Conduct.
- Measurement
Overall dimensions and glass thickness to be compared
to those specified on manufacturers lists
- Testing
- Glass edges to be submitted to Sharp Edge Test
using the method described for the Safety of Toys
in EN7l Part 1:1988 (BS 5665 Part 1:1989) Clause
4.18.
- Aquaria will be filled to normal working depth
and inspected after 24 hours.
- Aquaria tanks to be tested at twice the intended
working pressure for 24 hours.
This test will be completed with either:
An impact test should be undertaken as outlined below:
- use of a 5kg rubber ball swung on a pendulum length
1.45 m from a distance simulating a drop equivalent
to 25cm height into the mid point of a front plate
of the aquarium (this uses the principles only of
BS 6206, 1981 for domestic glass)
- use of a 230g steel ball using the technique described
above (this uses the principles only of BS 3193
for oven doors.)
- (Testing will be terminated if any aquaria fails
any test and reported to the manufacturer who will
be invited to resubmit as appropriate.)
