The following standards apply for hydrogen
(The identified test methods are incorporated herein by reference):
Specifications for Hydrogen | ||
| Specification | Value | Test Method |
| Hydrogen | 98.0 mole % (min.) | ASTM D 1946-90 |
| Combined hydrogen, water, oxygen and nitrogen | 99.9 mole % (min.) | ASTM D 1946-90 for hydrogen, nitrogen and nitrogen oxygen; ASTM D 1142-90 for water using the Bureau of Mines apparatus |
| Total hydrocarbons | 0.01 mole % (max.) | ASTM D 1946-90 |
| Particulate matter | a | |
| Odorant | b | |
| __________ | ||
a The hydrogen shall not contain dust, sand, dirt, gums, oils, or other substances in an amount sufficient to be injurious to the fueling station equipment or the vehicle being fueled.
b Starting 1/1/95, the hydrogen fuel at ambient conditions must have a distinctive odor potent enough for its presence to be detected down to a concentration in air of not over 1/5 (one-fifth) of the lower limit of flammability. This requirement applies only to hydrogen which is introduced into the vehicle fuel storage system in gaseous form.
