NOTE: The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows.

ISO 14175 : 2008 Welding consumables – Gases and gas mixtures for fusion welding and allied processes (MOD)

In addition, symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/lEC Guide 21-1.

This Standard provides general information about contaminants in compressed air systems as well as links to the other parts of JIS B 8392, either for the measurement of compressed air purity or the specification of compressed air purity requirements.

In addition to the above-mentioned contaminants of particles, water and oil, this Standard also identifies gaseous and microbiological contaminants.

Guidance is given in Annex A as to the application of this Standard.

NOTE: The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows:

The symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/IEC Guide 21-1.

Residential and home applications to fuel land vehicles are not covered.

NOTE These recommendations are in addition to applicable national regulations and codes, which can prohibit certain aspects of this document.

It is applicable to fuelling for light duty hydrogen land vehicles, but it can also be used as guidance for fuelling buses, trams, motorcycles and fork-lift truck applications, with hydrogen storage capacities outside of current published fuelling protocol standards, such as SAE J2601.

Residential applications to fuel land vehicles and non-public demonstration fuelling stations are not included in ISO/TS 19880-1:2016.

It provides guidance on the following elements of a fuelling station:

– hydrogen production/delivery system

– delivery of hydrogen by pipeline, trucked in gaseous and/or liquid hydrogen, or metal hydride storage trailers;

– on-site hydrogen generators using water electrolysis process or hydrogen generators using fuel processing technologies;

– liquid hydrogen storage;

– hydrogen purification systems, as applicable;

– compression

– gaseous hydrogen compression;

– pumps and vaporizers;

– gaseous hydrogen buffer storage;

– pre-cooling device;

– gaseous hydrogen dispensers.

"Hydrogen" in this paper means normal hydrogen (¹H₂), not deuterium (²H₂) or tritium (³H₂).
