The film is defined as “degraded” when, subjected to laboratory testing in order to determine its elongation to breaking point value (according to the ASTM D882 method), it obtains a result of less than 50% of its original value at the moment of installation (the same material, not subject to wear). Advanced degradation can be seen when the plastic film becomes rigid and loses resistance.
Reports of premature failure
For all claims regarding premature failure, please contact the Plastik Advanced direct sales representative, distributor representative or area agent for all preliminary matters as well as for the collection of useful information and samples.
All claims, together with all relative information, are passed on to the Plastik claims department for the appropriate analysis and relative technical response.
Inspections and sample collection
Direct personnel from Plastik Advanced, the distributor representative or the area agent will carry out an inspection of the area affected by the degradation in order to collect a sample of at least 100 x 100 cm of the affected material. It will be necessary to take a second sample for comparative analysis ONLY in the event that a second area with film from the same batch but with different levels of degradation is available. The samples, clearly identified, must be sent to Plastik (claims department).
At the moment of making claims, the following information will be required:
- Type of product
- Length and thickness
- Date of supply
- Date of installation
- Date of failure
- Agrochemical products used
- A copy of the delivery note
The results of the checks will be communicated to the client directly by Plastik Advanced personnel, the distributor representative or the area agent as soon as possible.
The guarantee explicitly excludes damages due to:
- Extreme weather conditions (hail, strong gusts of wind)
- The formation of rust on the structure
- Mechanical damage due to errors in storage, transport, conservation and/or installation.
- The use of acid products or organic solvents for the whitening or cleaning of the covering film.
- The exceeding of the limits for Sulphur and Chlorine on the surface of the film in compliance with CEPLA recommendations.
MAXIMUM limits permitted:
- Duration 2 years – Sulphur (ppm) : 1500
- Duration 3 years – Sulphur (ppm) : 2000
- Duration 2 years Chlorine (ppm) : 100
- Duration 3 years Chlorine (ppm) : 150
In any case, the exceeding of the upper limit of 1000 ppm/year of S and 70 ppm/year of Cl is not permitted.
These limits have been determined in compliance with the standardised method of analysis (as described in UNI EN 13206:2017)
- In tunnel structures (e.g. with arches) and multi-tunnels, the sections of film in contact with the structure must be painted with specific acrylic or vinyl paints in order to protect the film from excessive heat.
Paints with organic solvents or relative blends must be avoided UNI EN 13206:2017 G1.1.3.
- Claims not accompanied by the necessary documentation (for example the delivery note as proof of the consignment of the merchandise).
Responsibility of Plastik Advanced S.r.l.
The responsibility of Plastik Advanced S.r.l. is in any case limited to the substitution of the material in the quantity defined.
