Overview

ISO 19813:2006 is an international standard developed by the International Organization for Standardization (ISO) that specifies test methods and performance requirements for high voltage boots used on plug-top coils and pencil coils in road vehicles' ignition systems. These high voltage boots serve as critical insulating components ensuring reliable electrical performance and safety by preventing flash-over and electrical breakdowns under operating conditions. The standard provides a framework for manufacturers and suppliers to evaluate the quality, durability, and electrical insulation properties of these components according to consistent and rigorous protocols.

Key Topics

• Scope and Applicability
  ISO 19813:2006 covers all types of high voltage boots fitted on plug-top and pencil coils used in automotive ignition systems. This includes the testing of boot materials and assembly against mechanical and electrical stress.

• General Test Conditions
  Tests are conducted at room temperature (23 ± 5 °C) with unused test samples. The positioning of boots on spark-plug insulators and the application of grease, if required, follow customer specifications to simulate real operating conditions.

• Visual Examination
  Before and after testing, visual inspections assess appearances, workmanship, and detect defects such as cracking, discoloration, deformation, or water ingress that could impair boot functionality.

• Electrical Insulation Tests

  • Sealing Test: Evaluates the boot’s capability to prevent moisture ingress and maintain insulation when immersed in a saltwater solution under pulse voltage conditions (minimum 25 kV at 50 or 60 Hz).
  • Breakdown Test: Assesses boot resistance to electrical breakdown under high voltage exposure within a steel ball bath. Both tests require no flash-over or breakdown during continuous 10-minute operation.

• Test Setup
  The standard specifies an ignition coil and spark-plug assembly in a controlled fixture with appropriate environmental preconditioning (100 hours at 120 °C with 10%-95% humidity) to replicate harsh operating conditions.

Applications

• Automotive Ignition Systems
  High voltage boots compliant with ISO 19813:2006 ensure optimal performance and safety for ignition coils, critical in delivering reliable spark generation in internal combustion engines.

• Quality Control and Certification
  Manufacturers use the standard to validate product designs, materials, and manufacturing processes, confirming that boots withstand electrical and environmental stresses encountered in real-world applications.

• Supplier and Customer Agreements
  The standard supports clear technical communication between ignition coil manufacturers and component suppliers by defining test arrangements and acceptance criteria based on customer requirements.

• Research and Development
  Engineers can leverage ISO 19813 test methods to innovate and improve boot designs, enhancing thermal and electrical resistance properties and extending service life.

Related Standards

• ISO/IEC Directives
  Governs the drafting and approval processes for ISO standards, ensuring consensus and rigorous review for automotive component specifications.

• ISO/TC 22 Subcommittee SC 1
  Responsible for ignition equipment standardization, further overseeing quality and safety measures for related vehicular electrical components.

• Electrical Insulation Standards
  Complementary standards addressing electrical insulation materials and tests may be referenced for broader evaluation of components in ignition and high voltage systems.

---

By conforming to ISO 19813:2006, automotive engineers and manufacturers ensure that high voltage boots on plug-top and pencil coils meet stringent performance, safety, and durability requirements critical to the reliability of modern vehicle ignition systems. This standard plays an essential role in safeguarding electrical integrity and optimizing ignition performance in demanding automotive environments.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 19813 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 1, Ignition
equipment.
