DIN 50018 Test

Testing in a saturated atmosphere in the presence of sulfur dioxide

This standard specifies the general conditions and procedures for the testing of test specimens in condensation atmospheres in the presence of sulfur oxide — and specifically for sulfur dioxide concentrations that are not included in DIN EN ISO 6988:1997-03 — and which are required to be complied with to ensure that the results of tests carried out in different laboratories are reproducible. 

The tests described in this standard serve to assess the effectiveness of anti-corrosion systems and to quickly diagnose corrosion defects. 

If more than one anti-corrosion system is tested on more than one test material, it needs to be taken into account that the effect of sulfur dioxide on the test specimens might vary. 

The shape and preparation of test specimens, the duration of the test and the assessment of the test results are not covered in this standard. For information regarding these, the relevant standards and regulations shall be consulted or shall be agreed on a case-to-case basis. For the purpose of these tests, the specifications of DIN 50905-1 to DIN 50905-3 in particular shall be complied with. Further information is given in the Introduction to DIN EN ISO 6988:1997-03. 

The tests described here are assigned to the category ‘accelerated corrosion tests’ as in DIN EN ISO 8044. 

Sulfur dioxide concentration: *AHT 1,0 S. or AHT 2,0 S

Test Temperatures:  40+/- 3°C during the heating period, and the relative humidity approximately 100%. The cooling period temperatures around 18 to 28°C and the relative humidity max.75. 

Test Cycle:  8 hours of heating followed by 16 hours of cooling (test chamber opened or vented) off time.

*AHT stands for condensation climate with alternating humidity and air temperature.
