    John Deere Waterloo Standard

    APPROVED FOR DISTRIBUTION


    OUTSIDE JOHN DEERE RES 10526
    Specification for Protective Coatings for Fluid
    Handling Tubing
    1 Scope
    RES10526 specifies the corrosion protective coatings acceptable for fluid handling steel tubing. This
    standard applies only to steel tubing designed to carry oil, fuel, coolant, or air conditioning fluids. It
    does not cover tubing designed to carry exhaust gasses or to any tubing made of materials other than
    steel.
    This standard does not cover raw material specifications, cleanliness class, or requirements for
    fittings used in tube assemblies.

    2 Designation
    The coating requirements are designated according to RES10526 by the standard number followed
    by the category. The following five categories specify the acceptable coatings based on the
    appearance and corrosion protection requirements of the application. Drawing callout examples are
    provided for each category.

    Category A - Tubing that is internal to working assemblies

    Drawing callout example:


    COAT PER RES10526 CATEGORY A

    Category B - Tubing that will be top-coated as part of a higher level assembly

    Drawing callout example:


    COAT PER RES10526 CATEGORY B

    Category C - Tubing that will not be top coated, will not be visible on fully assembled
    tractor, but located where external surfaces may be subjected to corrosive materials

    Drawing callout example:


    COAT PER RES10526 CATEGORY C

    Category D - Chassis related tubing that will not be top coated as part of a higher level assembly, but
    will be visible

    Drawing callout example:

    3 Requirements

    If JDS-D85 or JDS-G253 is specified on a print, it shall supersede the RES10526 specification for
    biodiesel or ULSD (Ultra Low Sulfur Diesel) steel lines.
    If JDM F19 is specified on a print, it shall supersede the RES10526 specification for all hydraulic
    threaded tube assemblies.
    Compatibility
    Any RES 10526 coating shall meet John Deere safety and environmental requirements and shall be
    compatible with the tractor fluid carried by the tubing.
    Appearance
    Any RES 10526 coating shall not affect subsequent finish coat of paint, if applicable, such that it
    would cause it to not meet the requirements of JDM F17 or RWS1330.01.
    All category D and category E coatings must meet RWS1330.01 class C guidelines.
    Coating Process Options
    The coatings shall meet the requirements specified by the standards and designations provided in
    Table 1. The coating to be used must be specified and agreed upon during the DPAR process. The
    JDS-G223 supplier change request process shall be used to change coating once one has been
    established.

    Metallic Alloy Coating


    For RES 10526 tubing manufactured on or after 2015-01-01, when tested in accordance with
    ASTM B117 or ISO 9227, significant surfaces of the as-processed metallic alloy-coated tubing
    shall show neither sacrificial coating corrosion products (except at corners or edges) after a
    minimum of 120 hours nor base metal corrosion after a minimum 144 hours of continuous neutral
    salt spray. For RES 10526 tubing manufactured prior to 2015-01-01, the metallic alloy-coated
    tubing coating must meet or exceed 72 hour neutral salt spray (NSS) per ASTM B117 or ISO
    9227 with no visible signs of corrosion.

    The following shall be provided as part of each PPAP:


    a) Coating technical data sheet
    b) Process control plan identifying all critical coating characteristics and the testing performed to
    conform the coating meets these requirements
    c) A statement identifying Neutral Salt Spray (NSS) test method, the standard to which the part
    was tested and as-processed Neutral Salt Spray data values or results with clear indication of
    appearance of sacrificial coating corrosion and base metal corrosion per 24 hour period of
    testing.
    d) Sample parts as agreed upon by supplier and John Deere prior to or during the DPAR.

    Once the coating process is approved, the supplier shall verify to John Deere upon request that each lot has been
    processed in accordance with the requirements and process controls established above.
