Hydraulic fluid - high performance, readily biodegradable, saturated synthetic esters. ISO 15,22 Shell PANOLIN S4 HLP Synth is our highest performance and industry leading biodegradable saturated ester (HEES) type synthetic hydraulic fluid. Special zinc-free additive technology, formulated with high-performance fully synthetic saturated esters offer increased machinery efficiency through enhanced oil life and premium wear protection. Particularly suited for use in environmentally sensitive areas and in stationary and mobile hydraulic systems including construction, earthmoving and forestry.
Biodegradable hydraulic fluid HEES — ISO 15380
The international standard for biodegradable hydraulic fluids; class HEES is the synthetic ester type, the most used where a leak would reach water or soil.
Oxidation stability test method for turbine-type oils, part 3
ISO 4263 sets out test methods for determining oxidation characteristics of inhibited turbine-type/hydraulic oils; part 3 describes a dry TOST variant.Source
OECD 301B biodegradability above 60 %
A test result rather than a norm: OECD 301B measures the carbon dioxide evolved over 28 days. Above 60 % counts as "readily biodegradable", the threshold the environmental labels require.
Japanese Eco Mark environmental certification
Voluntary Japanese certification attesting a product's reduced environmental impact over its life cycle.Source
