General characteristics of liquefied natural gas

1 Scope

This Standard gives guidance on the characteristics of liquefied natural gas

(LNG) and the cryogenic materials used in the LNG industry. This Standard also

gives guidance on health and safety matters. This Standard is intended to act

as a reference document for the implementation of other standards of CEN/TC

282 (Installations and equipment for liquefied natural gas). This Standard is

intended as a reference for use by persons who design or operate LNG facilities.

2 Normative references

The following documents contain the provisions which, through reference in this

Standard, become the provisions of this Standard. For dated references, their

subsequent amendments (excluding corrigendum) or revisions do not apply to

this Standard. However, the parties who enter into agreement based on this

Standard are encouraged to investigate whether the latest versions of these

documents are applicable. For undated reference documents, the latest

versions apply to this Standard.

shore installation.

3 Term and definition

For the purposes of this Standard, the following term and definition apply.

liquefied natural gas

A colorless fluid in the liquid state composed predominantly of methane and

which may contain minor quantities of ethane, propane, nitrogen or other

components normally found in natural gas.

4 Abbreviations

For the purposes of this Standard, the following abbreviations apply.

- LNG liquefied natural gas;

- RPT rapid phase transition;
