What is ISO 20653:2023 Road vehicles -Degrees of protection (IP code)-Protection of electrical equipment against foreign objects, water and access?

ISO 20653:2023 Road vehicles specifies the degrees of protection provided by enclosures of electrical equipment in road vehicles against foreign objects, water ingress, and unauthorized access. This standard applies to road vehicles, irrespective of their type and size, but specifically focused on electrical systems and their components. ISO 20653:2023 adopts the IP (Ingress Protection) coding system, which is a well-established method for representing protection levels via a two-digit code, commonly known as the IP code.

The first digit of the IP code indicates the level of protection against ingress of solid foreign objects such as dust, dirt, and other particles. It ranges from 0 (no protection) to 6 (dust-tight). The second digit of the IP code defines the degree of protection against water, varying from 0 (no protection) to 9K (protection against powerful high-temperature water jets).

Given the critical importance of electrical systems in modern road vehicles, this standard is essential to ensure that these components are adequately protected against environmental factors that could compromise their performance, safety, or longevity. For instance, an IP code of IP67 means that the equipment is dust-tight (indicated by the ‘6’) and can withstand temporary immersion in water (indicated by the ‘7’).

Therefore, for organizations engaged in the design, manufacture, or testing of road vehicles or related electrical equipment, compliance with ISO 20653:2023 serves as a benchmark for product quality and safety. It is highly important for such organizations to seek certification to ensure compliance with this standard, as it demonstrates a commitment to providing products that meet robust safety and performance criteria.

For an organization like Pacific Certifications, which specializes in management system certifications and product certifications, the scope of this standard would fall under product certifications. Companies interested in certifying their road vehicle electrical equipment against ISO 20653:2023 may find it beneficial to engage the services of a certification body accredited by ABIS, such as Pacific Certifications. This would provide added assurance to stakeholders that the products meet the highest standards of safety and quality.

What are the requirements ISO 20653:2023 Road vehicles?

The ISO 20653:2023 standard sets forth a series of requirements which aim at evaluating the protection levels of enclosures for electrical equipment used in road vehicles. The standard employs the Ingress Protection (IP) code system to categorize the degree of protection provided. Below are the key components and requirements:

Ingress Protection (IP) Code

The standard uses the IP code system, comprising two digits. The first digit represents the level of protection against solid foreign objects (like dust or dirt), and the second digit denotes the level of protection against liquids (primarily water).

First Digit: Protection against Solid Objects

  • 0: No special protection
  • 1: Protection against solid objects larger than 50mm
  • 2: Protection against solid objects larger than 12.5mm
  • 3: Protection against solid objects larger than 2.5mm
  • 4: Protection against solid objects larger than 1mm
  • 5: Protection against dust; limited ingress allowed
  • 6: Dust-tight

Second Digit: Protection against Liquids

  • 0: No special protection
  • 1: Protection against vertically dripping water
  • 2: Protection against vertically dripping water when tilted up to 15 degrees
  • 3: Protection against water spray up to 60 degrees from vertical
  • 4: Protection against water splashing from any direction
  • 5: Protection against water jets from any direction
  • 6: Protection against powerful water jets from any direction
  • 7: Protection against temporary immersion in water
  • 8: Protection against continuous immersion in water
  • 9K: Protection against high-pressure and high-temperature water jets

Testing Protocols-ISO 20653:2023 Road vehicles

The standard specifies a variety of tests to validate each degree of protection, including:

  • Dust tests: These involve placing the equipment in a dust chamber to evaluate its resistance to dust ingress.
  • Water tests: A range of tests are used, such as drip boxes, spray nozzles, and immersion tanks, to evaluate how well the equipment resists water ingress.


Comprehensive documentation need to prove compliance with the standard. This includes test reports, quality assurance plans, and a declaration of conformity.

Marking and Labeling

Products that meet the standard’s requirements should be appropriately marked with their IP rating.

In summary, for organizations like Pacific Certifications, which are accredited by ABIS to issue product certifications, compliance with ISO 20653:2023 can be assessed and certified. This helps manufacturers demonstrate to stakeholders that their electrical equipment for road vehicles meets industry standards for safety and performance. Given the increasing complexity and critical role of electrical systems in modern road vehicles, achieving this certification can serve as a significant competitive advantage.

What are the benefits of ISO 20653:2023 Road vehicles?

ISO 20653:2023 Road vehicles specifies the degrees of protection provided by enclosures of electrical equipment in road vehicles against foreign objects provides a structured framework for evaluating the robustness of electrical equipment in road vehicles against external influences like foreign objects, water, and unauthorized access. The adoption of this standard offers several key benefits:

Enhanced Product Quality and Reliability

Adherence to ISO 20653:2023 ensures that the electrical components in road vehicles are designed and manufactured to meet strict criteria for durability and functionality. This results in higher product quality, with a reduced likelihood of failure due to environmental factors.
