The impact test required for forgings used in critical applications shall be subject to special consideration by the Administration.

The requirements for design temperatures below -165°C shall be specially agreed with the Administration.

For materials 1.5% Ni, 2.25% Ni, 3.5% Ni and 5% Ni, with thicknesses greater than 25 mm, the impact tests shall be conducted as follows:

| Material thickness (mm) | Test temperature (°C) |
|--------------------------|---------------------|
| 25 < t ≤ 30               | 10°C below design temperature |
| 30 < t ≤ 35               | 15°C below design temperature |
| 35 < t ≤ 40               | 20°C below design temperature |

The energy value shall be in accordance with the table for the applicable type of test specimen. For material thickness of more than 40 mm, the Charpy V-notch values shall be specially considered.

For 9% Ni steels, austenitic stainless steels, high manganese austenitic steels and aluminium alloys, thickness greater than 25 mm may be used.

The chemical composition limits shall be in accordance with recognized standards.

TMCP nickel steels will be subject to acceptance by the Administration.

A lower minimum design temperature for quenched and tempered steels may be specially agreed with the Administration.

A specially heat-treated 5% nickel steel, for example triple heat-treated 5% nickel steel, may be used down to -165°C, provided that the impact tests are carried out at -196°C.

The impact test may be omitted, subject to agreement with the Administration.

The use of the material shall be subject to the required conditions specified by the Administration based on the Guidelines developed by the Organization.*

The impact test may not be omitted for high manganese austenitic steel.”

* Refer to the Revised guidelines on the application of high manganese austenitic steel for cryogenic service (MSC.1/Circ.1599/Rev.2).
