Overview

EN 60512-19-3:1997, published by CLC, specifies a standardized testing procedure to evaluate the chemical resistance of electromechanical components used in electronic equipment. This part of the IEC 60512 series focuses specifically on Test 19c – Fluid Resistance, which assesses the impact of accidental exposure to various fluids and lubricants on electrical connecting devices. The standard is essential for manufacturers, testing laboratories, and quality assurance teams seeking to verify durability and reliability of connectors and similar components under real-world chemical exposure conditions.

Understanding fluid resistance is crucial for ensuring that connectors maintain electrical performance, mechanical integrity, and safety during use in environments where exposure to fuels, hydraulic fluids, greases, cleaning agents, or other chemicals could occur.

Key Topics

• Scope and Object: Defines the purpose to assess effects of accidental fluid contact on electromechanical connectors.
• Test Specimens: Components fitted with accessories and wired per detail specifications to simulate real conditions.
• Conditioning Cycles:
  • Immersion or grease application phase at specified temperatures.
  • Storage under normal atmospheric conditions.
  • Ageing phase with elevated temperature in an oven.
• Test Fluids: Includes various fluid families such as fuels, hydraulic fluids (mineral and synthetic), liquid lubricants, de-icing liquids, extinguishing liquids, and greases.
• Measurement Procedures: Visual exams, insulation resistance, contact resistance, engagement/separation force, and contact retention after conditioning.
• Test Parameters: Number of cycles, temperature controls, duration of fluid exposure, and fluid temperatures are adjustable based on detail specifications.
• Acceptance Criteria: No operational defects, legible markings post-test, and compliance with detailed technical specifications.
• Normative References: References IEC 60512 parts covering electrical continuity, contact resistance, insulation, voltage stress, and mechanical tests related to connectors.

Applications

EN 60512-19-3:1997 is widely applicable in industries such as:

• Electronics Manufacturing: Ensuring connectors in consumer electronics, industrial controls, and computing devices withstand chemical exposure.
• Automotive and Transportation: Testing electrical connectors susceptible to fuels, hydraulic fluids, greases, and cleaning agents used in vehicles.
• Aerospace and Defense: Verifying reliability of connectors exposed to varied fluid types under harsh conditions.
• Renewable Energy: Evaluating fluid resistance in connectors used in wind turbines or solar installations where environmental exposure is a concern.
• Industrial Automation: Guaranteeing connector performance in manufacturing environments involving lubricants and cleaning fluids.

By conforming to this standard, manufacturers can demonstrate product robustness and compliance with international testing methods that help reduce failures due to chemical exposure.

Related Standards

• IEC 60512-2: General examination, electrical continuity, and contact resistance testing methods.
• IEC 60512-3: Insulation resistance testing specific to electromechanical components.
• IEC 60512-13: Testing engagement and separation forces of connectors.
• IEC 60512-15: Contact retention testing in connector inserts.
• IEC 60512-19: Broader chemical resistance tests covering other subsections beyond fluid resistance.
• ISO Standards: Complementary standards related to mechanical and environmental testing of connectors may be referenced depending on regional or sectorial compliance.

FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, the IEC publishes International Standards. Their preparation is
entrusted to technical committees; any IEC National Committee interested in the subject dealt with may
participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. The IEC collaborates closely with the International Organization
for Standardization (ISO) in accordance with conditions determined by agreement between the two
organizations.
2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, an
international consensus of opinion on the relevant subjects since each technical committee has representation
from all interested National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical reports or guides and they are accepted by the National Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60512-19-3 has been prepared by IEC subcommittee 48B:
Connectors, of IEC technical committee 48: Electromechanical components and mechanical
structures for electronic equipment.
The text of this standard is based on the following documents:
