NOTICE

EIA Engineering Standards and Publications are designed to serve the public interest

through eliminating misunderstandings between manufacturers and purchasers,

facilitating interchangeability and improvement of products, and assisting the purchaser

in selecting and obtaining with minimum delay the proper product for his particular

need. Existence of such Standards and Publications shall not in any respect preclude

any member or nonmember of EIA from manufacturing or selling products not

conforming to such Standards and Publications, nor shall the existence of such

Standards and Publications preclude their voluntary use by those other than EIA

members, whether the standard is to be used either domestically or internationally.

Standards and Publications are adopted by EIA in accordance with the American

National Standards Institute (ANSI) patent policy. By such action, EIA does not

assume any liability to any patent owner, nor does it assume any obligation whatever to

parties adopting the Standard or Publication.

This standard is based upon the major technical content of International

Electrotechnical Commission standard 512-2, test 4a, voltage proof, 1985. It conforms

in all essential respects this IEC standard.

This Standard does not purport to address all safety problems associated with its use or

all applicable regulatory requirements. It is the responsibility of the user of this

Standard to establish appropriate safety and health practices and to determine the

applicability of regulatory limitations before its use.

摘要：

ANSI EIA-364-20C-2004 是美国国家标准学会（ANSI）与电子工业联盟（EIA）联合发布的电连接器及插座温升测试标准，属于 EIA-364 系列规范之一。该标准详细规定了在额定电流条件下测量电连接器接触界面温升的试验方法，包括测试样品的安装要求、环境温度控制、电流施加时长、热电偶布置位置及数据记录步骤。它适用于各类电连接器、端子及互连元件，旨在确保连接器在长期通电工况下的热性能满足可靠性要求，为产品设计、质量验证及合规性评估提供统一依据。标准版本中的“C”表示第三次修订，替代了
