We do not rely solely on the results of various laboratories or manufacturers' specifications. All our statements about the durability and authenticity of our flags and banners are based on our own empirical observations, which we make at our numerous test stations.
We have been operating several flag test stations at altitudes of between 1,100 and 1,300 meters at Pass Thurn between Mittersill and Kitzbühel since 1999, i.e. for over 20 years. Here, we constantly measure wind speed and solar radiation and correlate the determined values directly with the dyes, flag fabrics and assemblies to be tested.
Constant wind with an average speed of 19 km/h throughout the year offers the optimal conditions for comprehensible and meaningful tests of substrates, printing inks and various assemblies.
In addition, the external conditions (wind strength and solar radiation) are constantly documented by measurements.
Over the last two decades, this has resulted in around 100 field reports on the durability of various fabrics, printing inks and assemblies. These experiences were finally bundled in the development of POWERFLAG and led to this unique product.
The unique selling points of POWERFLAG are
Laboratory tests attempt to recreate the conditions of nature on a small scale as closely as possible and have the advantage that they are always absolutely identical. This means that the individual tests are exactly comparable with each other. However, we have found at all levels of technology that although laboratory tests always provide good indications, the results in "real life" are always different. And so nature, with sunlight of various intensities, drizzle to heavy rain, light breezes to storms, provides a much wider range of influencing variables than a laboratory can offer. Admittedly, you need much more time for a test in the wild than in the laboratory. It often takes 1.5 to 2 years before we have a result. Nevertheless, a result that takes all facets of the weather into account is more meaningful.
Basically, we primarily check how quickly a test flag breaks down. We evaluate this quite simply according to a predefined scheme in degrees of destruction from 0 - 10. Since the beginning of the recordings, these evaluations have been incorporated into a durability diagram that shows the course of the destruction of a flag, as well as fastness values for dyes from the various production types over the course of a calendar year. All this is the basis for being able to recommend the right FAHNENGÄRTNER product for your application.
The basis for these results is an average wind speed of 19 km/h over the entire calendar year and the hoisting of the flags from wind force 7 (approx. 60 km/h).
We can also see, for example, that the corners of a flag are always rounded off in the wind. This observation gave rise to the PLUS variants of our individual quality levels. By rounding the corners, we anticipate nature and thus significantly extend the durability.
Our experience with the seemingly simple product "flag" grows with every test and every observation we make on the test site, making us an experienced and competent partner for you.
Grade 1
Sewing thread begins to loosen a little.
Grade 2
Seam begins to tear over a length of 1-2 cm.
Grade 3
The damage to the suture increases to a length of 3-5 cm.
Grade 4
The first minor damage appears on the flag leaf.
Grade 5
The fabric itself is tearing more and more
and warp stitch seams are open over almost the entire bottom edge.
Grade 6
The outer edge also shows the first major damage (seam and fabric).
Grade 7
The lower right corner begins to round off clearly.
Grade 8
The fabric begins to tear in strips or "wears off" more and more.
Grade 9
More than 10% of the fabric width has already been torn away at the corner.
Grade 10
The flag is badly damaged.
