ECSS-E-30 Part 1A – Mechanical – Part 1: Thermal control (25 April 2000)

This Standard has been cancelled and replaced by ECSS-E-ST-31C (15 Nov 2008).


Part 1 of ECSS-E-30 in the engineering branch of ECSS Standards defines requirements for the discipline of thermal engineering.

This Standard defines the requirements for the definition, analysis, design, manufacture, verification and in-service operation of thermal control subsystems of spacecraft and other space products.

This Standard applies to the thermal engineering activities of all spacecraft and space related products for all thermal aspects and temperature levels for space products.

For this Standard, the complete temperature scale is divided into 3 ranges defined as follows:

  • Cryogenic temperature range, below 120 K;
  • Conventional temperature range, between 120 K and 420 K;
  • High temperature range, above 420 K.

The core part of this Standard concerns the conventional temperature range; complementary information, requirements and definitions for the cryogenic and high temperature range respectively are provided in annexes B and C.

When viewed from the perspective of a specific project context, the requirements defined in this Standard should be tailored to match the genuine requirements of a particular profile and circumstances of a project.

NOTE Tailoring is a process by which individual requirements of specifications, standards and related documents are evaluated, and made applicable to a specific project by selection, and in some exceptional cases, modification of existing or addition of new requirements.

This Standard is applicable to:

  1. thermal engineering activities of all space and space related products, covering all thermal engineering aspects involved in the achievement of the required thermal performance, particularly: design, verification, manufacturing and in service operations;
  2. thermal control subsystem and to relevant parts of all space products.
