R  fluids (Type IV). The Material Numbers (Mat No.) are as follows: 
R  - 02-003, 
R  - 02-003A, 
R  - 02-003B, 
R  - 02-003C, 
R  - 02-003D. 
R  (2) The hydraulic fluid is specified by the operator. All fluids are to 
R  NSA 307110 specification. They can be mixed. 
R  (3) Fluid Characteristics. 
R  (Ref. Fig. 001) 
R  B. Fluid Monitoring 
R  (1) Hydraulic fluid with a high degree of cleanliness is required for the 
R  correct operation of the hydraulic systems and equipment. 
R  (2) Frequently sampling, particle counting (physical contamination) and 
R  the inspection of filter clogging indicators monitors the hydraulic 
R  fluid. 
R  (3) If the filter clogging indicator is shown you must: 
R  - Shut down the associated hydraulic system, 
R  - Replaced the clogged filter, 
R  - Take a sample of the system hydraulic fluid and send it for 
R  analysis. 
R  (4) On results of the analysis record (physical contamination), reclaim 
R  the hydraulic fluid, 
R  - (Ref. 12-36-29-600-004), 
R  - (Ref. 12-36-29-600-005), 
R  - (Ref. 12-36-29-600-006). 
R  NOTE : The number of particles contained in 100 cm3 (6.10 in.3) of____ 
R  hydraulic fluid must not exceed the class 9 requirements of 
R  the NAS specification 1638 (final or rejection state).

R R R R  NOTE : The degree of cleanliness of the hydraulic fluid used for____ replenishing (topping up of the hydraulic systems and hydraulic cart reservoirs) must be consistent with class 7 of the NAS specification 1638 (initial state). 
R R R  C. Hydraulic Ground Power Cart Only hydraulic ground power carts with a hydraulic reservoir must be used. 
R R  Fluid sampling for contamination of the hydraulic fluid shall be monitored and the sample analysis record kept on file.
 D. Hydraulic Fluid Property In-Service limits. The hydraulic fluid property in-service limits are: - The physical properties, - The chemical properties. (Ref. Fig. 002)
 NOTE : The maximum water contents permitted by the manufacture in____ hydraulic fluids is 0.8 %. But this limit together with very high temperatures decreases the life of the hydraulic fluids. Airbus Industrie thus recommends to decrease the limit to 0.5 % which
 will increase the life of the hydraulic fluid.
 (1) The quality of the hydraulic fluid must be in the limits given in Fig. 002.
 (a) If the water or chlorine content of the hydraulic fluid are equal or more than the permitted values: Clean it with the HYDRAULIC PURIFIER (HSPA181-380J): - (Ref: 12-36-29-615-001) - (Ref: 12-36-29-615-002) - (Ref: 12-36-29-615-003) Or change the hydraulic fluid: - (Ref: 12-36-29-600-001) - (Ref: 12-36-29-600-002) - (Ref: 12-36-29-600-003)
 (b) If the acidity, density or viscosity of the hydraulic fluid are more than the permitted values: Change the hydraulic fluid: - (Ref: 12-36-29-600-001) - (Ref: 12-36-29-600-002) - (Ref: 12-36-29-600-003)
 (c) If the conductivity of the hydraulic fluid is less than the permitted value: Change the hydraulic fluid: - (Ref: 12-36-29-600-001) - (Ref: 12-36-29-600-002) - (Ref: 12-36-29-600-003)
