Overview

EN 60512-14-7:1998 is an international standard developed by the CLC (European Committee for Electrotechnical Standardization) that specifies the basic testing procedures and measuring methods for electromechanical components used in electronic equipment. This particular section, Part 14, Section 7 (Test 14g), focuses on sealing tests related to impacting water. The standard defines a test method to evaluate the effects of water or specified fluids hitting electrical connecting devices, ensuring these components maintain integrity and performance under conditions involving exposure to impacting water.

Key Topics

• Scope and Purpose

  • Defines a standardized procedure to test electromechanical components for resistance to impacting water.
  • Applied mainly to electrical connectors to predict performance under water exposure.

• Test Setup and Methodology

  • Specimens to be tested are prepared with normal accessories and wired as per detail specifications.
  • Initial insulation resistance measurement is performed to establish baseline performance.
  • The specimen is subjected to impacting water using an oscillating tube spray per IEC 60068-2-18, with specific parameters such as:
    • Spray nozzle angle: 60°
    • Oscillating angle: ±60°
    • Nozzle orifice diameter: 0.40 mm³
    • Water flow rate: approximately 0.10 dm³/min
    • Water pressure: ~80 kPa
    • Duration of fluid exposure: 10 minutes
  • The specimen is rotated during testing to simulate real-world conditions.

• Post-Test Evaluation

  • Insulation resistance is measured again within 5 minutes after the water exposure.
  • The insulation resistance must meet or exceed the minimum specified value in the detailed specification to pass the test.

• Specification Details

  • Number of specimens, wiring configuration, wire type, test duration, and fluid composition can be customized based on the detail specification.
  • Any deviations from the standard method should be clearly indicated.

Applications

• Electrical Connectors and Components

  • Used to verify sealing and durability of connectors in environments where exposure to water spray or splashing may occur.

• Quality Assurance in Electronics Manufacturing

  • Helps manufacturers ensure reliable operation of connector interfaces in appliances, industrial controls, automotive electronics, and outdoor equipment.

• Environmental Testing

  • Integral part of environmental qualification for electromechanical components exposed to moisture or intermittent water sprays.

• Product Development and Certification

  • Assists in certifying components in accordance with IP (Ingress Protection) ratings related to water ingress.

• Safety and Compliance

  • Essential for compliance with industry standards focused on the performance of electronic devices in harsh environmental conditions.

Related Standards

• IEC 60068-2-18 - Environmental testing, methods for water impact including oscillating tube spray tests.
• IEC 60512-1 - General procedures for basic testing of electromechanical components.
• IEC 60512-2 - Tests for general examination, electrical continuity, insulation resistance, and contact resistance.
• ISO/IEC Standards for Connectors - Standards related to performance and reliability of connectors in various applications.

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 correspondin
