Specifications of RIVIAN RMS.7002 Powder Coating Material

The “RIVIAN RMS.7002 Powder Coating Material Specifications” standard, developed by RIVIAN, an American electric vehicle (EV) manufacturer and automotive technology company, describes powder coating materials and processing characteristics for vehicles.

Powder coating consists of non-volatile components applied dry and bonded together by heat or radiation to form a continuous fused film for protective or decorative purposes. This standard contains minimum performance requirements for powder coating application. The requirements depend on the location and function of the powder coating and may be used alone or in combination with electroplating, priming, converting, zinc plating, or a topcoat paint in a system.

Rivian's RMS standards are internal engineering standards. They typically include the following:

• Chemical composition and mechanical properties (e.g., yield strength, tensile strength).
• Suitable forming, welding, and joining methods for high-volume electric vehicle production.
• Quality control, testing procedures, and acceptance criteria.
• Application-specific requirements for parts exposed to terrain conditions, extreme temperatures, or structural loads.

The RMS.7002 standard is used to define requirements for materials, components, or systems used in next-generation platforms. This standard ensures consistency, safety, and performance across all supplied parts.

The RMS.7002 standard generally includes the following requirements:

• Material performance requirements:
  • Mechanical properties (strength, elongation, durability)
  • Thermal resistance (important for electric vehicle battery environments)
  • Chemical resistance (liquids, electrolytes, cleaning agents)

These requirements ensure that the materials can withstand real-world operating conditions in electric vehicles.

• Environmental and aging resistance: This includes features that reflect the company's particular focus on outdoor and adventure-oriented vehicles:
  • UV resistance
  • Moisture and corrosion resistance
  • Temperature cycling performance

Electric vehicles are designed for a variety of climates, so the materials need to maintain their performance over time.

• Testing and verification methods:
  • Laboratory test procedures
  • Accept conditions
  • Sampling methods

These ensure that all suppliers verify materials in a consistent and repeatable manner.

• Compatibility with electric vehicle systems: Unlike traditional automotive standards, company-specific specifications typically highlight the following:
  • Compatibility with high-voltage systems
  • Fire safety and flammability behavior
  • Integration with lightweight structural designs

This is compatible with modern electric vehicle architectures where battery safety and efficiency are critical.

The requirements in the RMS.7002 standard are defined under the following headings:

• Process definition
• Chemistry
• Process/chemical control
  • Air quality
  • The maintenance schedule should be checked according to the minimum maintenance check table.
  • Curing and gas release
  • Dust control
  • Cleaning / pretreatment

The performance requirements in the RMS.7002 standard are listed under the following headings:

• Performance
• View
• Thickness
• Curing status
• Coating hardness
• Initial coating adhesion
• Scratch resistance
• Wear resistance
• Impact resistance
• Stone impact resistance
• heat resistance
• moisture resistance
• Temperature and humidity cycle resistance
• Chemical exposure resistance
• Cyclic corrosion testing
• Filamentous corrosion (aluminum only)
• Weather resistance test
• Thermal shock resistance

For example, in terms of appearance, the coating surface must be smooth/continuous and free from bubbles, separation, pitting, nodules, runoff, and contamination. Inspection should be performed visually with the naked eye and with an optical microscope at 10x magnification. The Class A surface appearance must be approved by Rivian.

In terms of thickness, the coating thickness should be in the range of 40-100 microns, unless recommended by the raw material supplier or otherwise approved by Rivian. For initial qualification, a thickness range, including maximum, minimum, and target, must be defined for production quality control. The method should be sectioning according to the ISO 1463 standard.

Regarding curing status, the curing status of the powder coating must be verified as part of batch-based quality and qualification control. Dual-solvent scrubbing can be used as this curing status verification method. This method involves moistening a white, soft cotton cloth (gauze or medical gauze) with the solvent and then rubbing the coated surface with firm finger pressure in circular or back-and-forth motions, 10 times for batch acceptance and 50 times for qualification. Approved solvents include n-butyl acetate, methyl ethyl ketone, and methyl isobutyl ketone. Other solvents may also be used if approved by Rivian.

The main reasons why the RMS.7002 standard is considered important are as follows:

• Supplier quality control: This standard reduces variability and defects by ensuring all suppliers deliver materials that meet Rivian's stringent performance criteria.
• Safety and reliability: Electric vehicles operate under high thermal and electrical stress. This standard helps ensure long-term durability and passenger safety.
• Brand consistency: Rivian positions itself as a premium, adventure-focused electric vehicle brand. Consistent material quality supports this:
  • Indoor durability
  • Outdoor durability
  • Overall vehicle lifespan

Rivian RMS specifications generally complement, but do not replace, global standards such as ISO (International Organization for Standardization), ASTM (American Society for Testing and Materials), and SAE (American Society of Automotive Engineers). Additional requirements are tailored specifically to Rivian's vehicle platforms.

The RMS.7002 standard is generally applicable to the following:

• Interior polymers or textiles
• Sealing materials (gaskets, insulation)
• Components near the battery
• Coatings or protective layers

These are critical areas in electric vehicle design, especially in terms of durability and safety.

In summary, the RMS.7002 standard is a proprietary material or component specification used by Rivian to ensure the use of high-quality, reliable, and safe materials in its vehicles. This standard plays a significant role in terms of supplier compliance, product consistency, and the overall performance of specific models.

For many years, our organization, with its competent and experienced staff, has been understanding the needs of its clients, providing the advanced testing services they require, and assisting them in the establishment, implementation, and improvement of management systems. Within this framework, we also provide testing services in accordance with the RIVIAN RMS.7002 standard.
