Proposal to clarify the test procedure to be applied in assessing compliance with the requirement for “compatibility with heat exchange fluids of non-metallic parts” Annex 5Q is part of UN Regulation No. 110. In Annex 4D, the wording “Compatibility with heat exchange fluids” is used but there is no reference to the applicable tests. The proposal clarifies that the “LNG heat exchanger – vaporizer” falls within Annex 5Q. The proposal correspondingly clarifies the general overview Figure 1-2, with all tests from Annex 5, and Table 5.1 in Annex 5.
