Foreword
This document (EN ISO 22775:2004) has been prepared by Technical Committee CEN/TC 309 "Footwear",
the secretariat of which is held by AENOR, in collaboration with Technical Committee ISO/TC 216 "Footwear".
This European Standard shall be given the status of a national standard, either by publication of an identical
text or by endorsement, at the latest by June 2005, and conflicting national standards shall be withdrawn at
the latest by June 2005.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic,

Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland
and United Kingdom.
1 Scope
This document specifies two methods for determining the propensity of a metal surface to either change
visually due to contamination by atmospheric pollution (Method 1: sulphide tarnishing), or to corrode due to
the action of salt water (Method 2: salt water corrosion).
2 Terms and definitions
For the purposes of this document, the following term and definition applies.
corrosion resistance
propensity of a metal surface either not to change visually due to chemical attack by atmospheric pollution, or
not to be altered due to the action of salt water
3 Principle
3.1 Method 1
A test specimen is stored in a moist atmosphere containing a low concentration of hydrogen sulphide gas for 1
h. The specimen is then assessed subjectively for signs of discoloration.
3.2 Method 2
Cotton lawn, saturated with sodium chloride solution, is wrapped around a test specimen. This assembly is
then stored in a sealed bag for 24 h at room temperature. The test specimen is then subjectively assessed for
signs of corrosion and the lawn assessed for staining.
4 Apparatus, materials and reagents
4.1 Method 1
4.1.1 Kipps generator or other hydrogen sulphide source.
WARNING — This equipment should be used only by qualified personnel owing to the extremely
toxicity of hydrogen su
