JDV 30 1 APPROVED FOR SUPPLIER DISTRIBUTION Scope 1.1 JDV 30 describes the prerequisites of a paint process to achieve the requirements of JDM F17 performance levels and JDM F20 performance classes. JDV 30 applies only to ferrous substrates. 1.2 JDV 30 is intended to be used in conjunction with JDM F17X2 and JDM F20X2 paint process qualification. Conformance to JDV 30 does not replace the requirement for qualification according to JDM F17X2 or JDM F20X2. 1.3 JDV 30 does not cover prerequisites for JDM F20 Class 1 or Class 2 performance. Qualification to JDM F20 Class 1 and Class 2 performance shall be determined by the JDM F20X2 process. This standard can contain mandatory provisions, which are identified by the words “shall” or “required”. Compliance with the mandatory provisions is required to claim conformance with this standard. This standard can also contain guideline provisions, which are generally identified by the words “should” or “recommended”. Compliance with the guideline provisions is not required, because they might not be appropriate for all machines or all applications. 1.4 2 Terms and Definitions For purposes of JDV 30, the following terms and definitions apply. 2.1 1K liquid dip Immersion paint process often using an alkyd resin. 2.2 1K liquid spray Paint process in which paint in liquid form is sprayed onto a substrate, and is capable of meeting JDM F20 requirements. 2.3 2K liquid spray Paint process in which paint in liquid form is sprayed onto a substrate: consisting of a base paint (resin and pigments), and a hardener (catalyst) which are mixed together just prior to application and is capable of meeting JDM F17 requirements. 2.4 autodeposition (A-coat) Immersion paint process in which chemical reactions deposit paint material on the substrate. 2.5 blast cleaned plus cleaner coater pretreatment Combination of a cleaner coater pretreatment with a preceding blast cleaning operation in which the added cleaning and surface texture from the blast cleaning achieves higher performance than a cleaner-phosphate pretreatment alone. 2.6 blast cleaned pretreatment Process which removes surface contaminants by propelling an abrasive media against the substrate. Note 1 Blast cleaning creates a texture on the substrate that aids in mechanical adhesion of the paint. The blast cleaning process shall be controlled to a minimum of blast cleaning grade Sa 2½ (very thorough blast cleaning) according to ISO 8501-1. 2 APPROVED FOR SUPPLIER DISTRIBUTION JDV 30 2.7 cleaner-coater pretreatment Iron phosphate or transition metal pretreatment systems that clean and apply conversion coatings in the same stage; typically, a spray system with a minimum of three pretreatment stages. 2.8 conversion coating Metal finishing process involving the application of a coating to a base substrate to prepare the surface for painting. 2.9 E-coat (electro-coat) Immersion paint process in which paint is plated onto a substrate using an electric current. 2.10 high edge paint material Paint materials designed for improved coverage on sharp edges to reduce corrosion initiating on exposed edges. Note 2 Edge coverage capabilities can be evaluated through testing according to JDQ 163 and JDQ 167. 2.11 iron phosphate cleaner-coater pretreatment Iron phosphate systems that clean and apply iron phosphate in the same stage, typically a spray system with a minimum of three pretreatment stages. Note 3 The iron phosphate coating mass per area for these systems is typically 220 mg/m2 to 760 mg/m2. 2.12 iron phosphate pretreatment System which utilizes separate cleaning and conversion coating states to apply iron phosphate coating by either a spray or immersion process; with a minimum of five pretreatment stages. Note 4 The conversion coating stage applies an iron phosphate conversion coating with a typical coating mass per area of 430 mg/m2 to 860 mg/m2. 2.13 manual wand wash pretreatment Manual pretreatment processes where a power sprayer system is used to clean and apply a conversion coating typically using modified cleaner-phosphate chemicals, but can also use ambient pretreatments. Note 5 Due to increased variation in a manual operation, these processes should be limited to applications where automated pretreatment is not feasible. 2.14 paint application Process (such as liquid spray, liquid, dip, powder spray) used to apply paint to a part. 2.15 Paint Materials Engineering Refers to the persons or departments at the enterprise or division level that are responsible for paint materials. 3 JDV 30 APPROVED FOR SUPPLIER DISTRIBUTION 2.16 paint process Combination of all steps and parameters for painting a substrate, including pretreatment, paint resin, paint application, and cure. 2.17 paint resin Binder or film forming component of a paint formulation. Note 6 Many types of resins are used in paint formulation. Most of the paints used on John Deere products can be classified as epoxy, acrylic, urethane, or polyester. 2.18 pretreatment Process used to prepare the surface of a part for painting. 2.19 pretreatment stages Individual spray or immersion process steps for the purpose of cleaning and rinsing a substrate and applying a conversion coating or a sealer to the substrate. 2.20 primer Paint material designed specifically for adhesion and corrosion resistance properties. 2.21 substrate Base material to be pretreated and painted. 2.22 thermoset powder Paint process in which paint in powder form is sprayed onto a substrate. Note 7 Thermoset powders melt and then irreversibly harden with adequate exposure to heat and time. 2.23 topcoat Paint material designed specifically for appearance, weathering, and aesthetic properties. 2.24 transition metal pretreatment Pretreatments which utilize separate cleaning and conversion coating stages containing little to no phosphate in the conversion coating, and operate at close to ambient temperatures. Note 8 The conversion coating typically applies a very light coating of a transition metal such as zirconium or vanadium. Application of the transition metal coating can be either a spray or immersion process with a minimum of five pretreatment stages. 2.25 zinc phosphate pretreatment Pretreatments utilizing separate cleaning and conversion coating stages in which the conversion coating stage applies a crystalline zinc phosphate coating with a typical coating mass per area of 1600 mg/m2 to 4300 mg/m2. Note 9 Application of the zinc phosphate coating may be either a spray or immersion process with a minimum of seven pretreatment stages. 4 JDV 30 APPROVED FOR SUPPLIER DISTRIBUTION 3 Abbreviations and Acronyms For the purposes of JDV 30, the abbreviations and acronyms in Table 1 apply.
