Table 2.16.1

Criteria for substances and mixtures corrosive to metals

Category	Criteria
1	Corrosion rate on either steel or aluminium surfaces exceeding 6,25 mm per year at a test temperature of 55 oC when tested on both materials.

Note U.K.

Where an initial test on either steel or aluminium indicates the substance or mixture being tested is corrosive the follow up test on the other metal is not required.

2.16.4. Additional Classification Considerations U.K.

2.16.4.1. The corrosion rate can be measured according to the test method of Part III sub-section 37.4 of the [F1 UN RTDG], Manual of Tests and Criteria. The specimen to be used for the test shall be made of the following materials: U.K.

(a)

for the purposes of testing steel, steel types

• S235JR+CR (1.0037 resp.St 37-2),

• S275J2G3+CR (1.0144 resp.St 44-3), ISO 3574 as amended, Unified Numbering System (UNS) G 10200, or SAE 1020;

(b)

for the purposes of testing aluminium: non-clad types 7075-T6 or AZ5GU-T6.
