NF F31-112 Railway Wagons - Test for Graffiti Related Protection

EUROLAB, together with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of NF F31-112 testing. This standard is called material extraction and product performance, anti-graffiti testing.

In Europe and the United States and other countries, the phenomenon of graffiti and the phenomenon of pasting small advertisements is relatively common. According to the data, the annual cost of removing graffiti in the UK exceeds 200 million pounds, and in the United States it exceeds 20 billion pounds. In China, the phenomenon of scribbles in urban underground passages, culverts and building facades has become increasingly serious in recent years. For rail transport vehicles, the evaluation and detection of NF F31-112 is especially important to better solve the problem of graffiti and small advertising.

It is generally believed that the surface of the product reaches the G31 and G112 levels of the NF F0-1 standard, which can effectively prevent small advertisements from sticking. For this, a barrier, that is, an anti-graffiti coating, should be applied on the surface of the product to be protected, thus making it difficult to scratch and facilitating the removal of graffiti pollution.

On the other hand, under normal circumstances, skin contact or wiping on the surface of the car body is easy to leave fingerprints or stains, which are difficult to clean and affect the overall appearance of the car body. The surface anti-fouling treatment is by spray coating or bonding.

In the form of anti-graffiti film, the anti-graffiti protective layer formed on the surface of the product must have the following properties:

• The cleaning agent used in the cleaning process does not cause abrasion or other damage to the surface of the product, so that it is resistant to solvent wiping.
• Resistance to sticking and repeated sticking, as well as the use of high and low temperature environments, should be simulated and tested. Standard GB/T 2792-1998 "180° in China
• Test Method for Peeling Pressure Strength Sensitive Tapes" are often used for testing.
• Weather resistance, coating or protective film does not suffer from falling off and performance degradation after prolonged exposure to wind and sun.
• Common dirt such as anti-graffiti properties, markers and shoe polish should be easily wiped off the surface of the product.
