Chromium-6 Test

General use of the test kit

With this TK11 Chromium-6 Detection Test Kit, you can easily test if your surface contamination, dust particles, coatings or paint layers contain chromium-6. To carry out the test, rub the moistened end of the swab on the object or material in question. If the swab remains light orange, no chromium-6 is present. If the swab turns red/purple, the object or material contains chromium-6. This change in color only occurs with chromium-6 (VI), and not with other (harmless) types of chromium such as chromium-3 (III).

Testing of surface contamination and dust particles for chromium-6

With this test kit you can easily test if your surface contamination or dust particles contain chromium-6. Surface contamination may occur, for example, when a (metal or stainless steel) surface was brought in contact with a lubricant, grease or anti-seize paste (such as P-37 for stainless steel nuts and bolts) followed by a heat treatment. This will lead to the formation of yellow calcium chromate (CaCrO4) which contains chromium-6. Dust particles may be the result of processing steps such as welding, grinding or sanding. If this surface contamination or these dust particles contain chromium-6, the test will give a red/purple result. If they do not contain chromium-6, the test will give an orange result. This gives you a simple indication whether your surfaces or dust particles are safe or not.

Testing of paint layers for chromium-6

The test kit enables you to test a paint layer (or primer layer) for chromium-6. To carry out the test, make a few incisions into the layer and sand the layer lightly with a clean sandpaper. Moisten the end of the cotton swab with test liquid and rub the cotton swab onto the paint layer. If the layer contains chromium-6, the cotton swab will turn purple. If no chromium-6 is present in the paint layer, the cotton swab will remain yellow/orange.

Testing of other materials

The test kit can also be utilised to test electrical components, impregnated wood and other materials.

About chromium-6

Chromium-6 is also known as chrome(VI), chromium(VI), Cr(VI), Cr6+ or hexavalent chromium. It is very harmful and can cause cancer. Compounds such as chromium(VI)oxide, zinc chromate, lead chromate, strontium chromate, chromates and dichromates contain chromium-6 and have been often used in the paint and steel industry because of their ability to resist oxidation and the formation of rust. Due to these properties, these compounds have been often used in protective paint for stainless steel and aluminium in trains and military vehicles. Moreover, chromium-6 is present on the surface of stainless steel that was subjected to heated anti-seize paste. Therefore, it is often present on the surface of for example gas turbine parts.

Chromium-6 is very toxic and carcinogenic. The processing (e.g. sanding) of old chromium-6 coatings or paint layers therefore poses great health risks, because dust with chromium-6 is released which can then be inhaled or absorbed through the skin.
