ISO 7137-1995 PDF

Full title and description

Aircraft — Environmental conditions and test procedures for airborne equipment. This International Standard lists the environmental conditions and associated test procedures used to qualify equipment intended for use on aircraft, with primary orientation toward civil and transport aircraft applications.

Abstract

ISO 7137:1995 cancels and replaces the 1992 edition and provides a concise listing of environmental conditions and standardized test procedures for airborne equipment. It is intended to harmonize test-condition definitions for manufacturers, test laboratories and certification bodies involved in aircraft equipment qualification.

General information

• Status: Published (4th edition, 1995).
• Publication date: June 1995 (1995-06).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 49.020 (Aerospace).
• Edition / version: 4 (ISO 7137:1995).
• Number of pages: 4 pages.

Scope

Defines and lists the environmental conditions and test procedures applicable to airborne equipment, providing a reference framework for selecting test categories and severities relevant to civil and transport aircraft. The standard functions as a harmonized listing rather than a detailed test-methods manual, and it is commonly used alongside other in-depth procedural standards.

Key topics and requirements

• Identification of standard environmental categories and severity levels relevant to aircraft equipment (temperature, humidity, vibration, shock, pressure/altitude, corrosive atmospheres, sand/dust, etc.).
• Listing of corresponding test procedures or references to established test methods for airborne applications.
• Guidance on the intended application domain (primarily civil and transport aircraft) and the relationship to certification and qualification activities.
• Harmonization with related aerospace environmental standards to support consistent test selection and reporting.

Typical use and users

Used by avionics and aircraft equipment manufacturers, environmental test laboratories, certification authorities and design engineers to define applicable environmental categories and to coordinate test programs during qualification and acceptance. Test houses and procurement/specification authors use it as a checklist or cross-reference when preparing test plans.

Related standards

Commonly used alongside RTCA DO-160 / EUROCAE ED-14 (environmental conditions and test procedures for airborne equipment), which provides the detailed procedural content most frequently applied in industry; also cross-referenced with military and general environmental standards such as MIL-STD-810 and IEC 60068 for non-aircraft-specific environmental methods. ISO 7137 has been prepared to align with and endorse sections of DO-160/ED-14 in the aerospace context.

FAQ

Q: What is this standard?

A: ISO 7137:1995 is an international standard titled "Aircraft — Environmental conditions and test procedures for airborne equipment" that lists environmental conditions and test procedures used to qualify aircraft equipment.

Q: What does it cover?

A: It provides a harmonized listing of environmental categories and associated test procedures (temperature, humidity, vibration, shock, altitude/pressure, corrosion/salt fog, sand/dust, etc.) and indicates their relevance for airborne equipment, particularly for civil and transport aircraft. It is intended as a reference framework rather than an exhaustive procedural manual.

Q: Who typically uses it?

A: Avionics and aircraft equipment manufacturers, environmental test laboratories, certification authorities, design and reliability engineers, and procurement/specification authors use the standard to define applicable environmental categories and to coordinate qualification testing.

Q: Is it current or superseded?

A: ISO 7137:1995 replaced the 1992 edition; it is the 1995 (4th) edition. Users should verify with ISO or national standards bodies for any later revisions, national adoptions or confirmations before assuming it is the most current normative reference for a given project.

Q: Is it part of a series?

A: ISO 7137 is part of aviation/aerospace environmental standardization activity and is routinely used alongside related documents (notably RTCA DO-160 / EUROCAE ED-14) and other environmental standards; it is one element in the broader set of standards for airborne equipment qualification.

Q: What are the key keywords?

A: Aircraft, airborne equipment, environmental conditions, test procedures, avionics qualification, vibration, shock, temperature, humidity, corrosion, DO-160, ED-14.
