SAE J1704 — DOT 4 brake fluid
SAE standard for DOT 4 brake fluids, with a higher boiling point than DOT 3, particularly once the fluid has taken up water.
FMVSS 116 DOT 4 — brake fluid
The US federal safety regulation defining the DOT brake fluid levels. DOT 4 demands a high boiling point both dry and after water uptake.
Brake fluid Class 4 — ISO 4925
The international standard for glycol brake fluids; class 4 matches the DOT 4 level, with a high boiling point both dry and wet.
UNE 26-109-88 — engine oil (Spain)
Spanish national engine oil standard from the 1980s.
