Summary This standard specifies the classification of low corrosivity of indoor air. This section applies to the characterization of metals and alloys and metallic coatings in storage, transport, influential during the installation and operation of the indoor use of low- corrosive atmosphere. This section provides the corrosive effects of a standard sample using a specified metal during a fixed exposure being to determine the classification of indoor atmospheric corrosion. A detailed description of the important parameters suitable for indoor atmospheric corrosion evaluation basis of the tomb.

Foreword

GB/T 24513 "Atmospheric corrosion of metals and alloys Classification of low corrosivity" is divided into three parts. --- Part 1. Indoor atmospheric corrosion measurement and evaluation; --- Part 2. Determination of indoor atmospheric corrosion; --- Part 3. Determination of indoor environmental parameters of atmospheric corrosion. This is Part 1 GB/T 24513 of. This section is equivalent international standards ISO 11844-1.2006 "Atmospheric corrosion of metals and alloys Classification of low corrosivity Part 1. Indoor atmospheric corrosion measurement and evaluation "(in English). For ease of use, this section made the following editorial changes. "." --- With a decimal point instead of a comma as the decimal point, ""; --- Deleted international standard directory, foreword and introduction; --- Normative references by corresponding national standards were changed. This section of the Appendix A, Appendix B, Appendix C and Appendix D is an informative annex. This part is proposed by the China Iron and Steel Association.
