This document specifies the requirements for producing and testing an unsealed anodic coating on titanium and titanium alloys. The anodic coating is produced by the sulfuric acid process. The coating is used with solid film lubricants for protection of titanium fasteners against galling, for limited protection of less noble metals against galvanic corrosion when in contact with titanium or for other approved uses.

This standard specifies the method of test for determining the solar absorptance of paints and varnishes.
The test procedure determines the amount of energy reflected by the material in the range of wavelengths at which there is energy from the sun hitting the Earth’s surface, and with the aid of a standard solar spectrum it allows a calculation to determine the solar absorptance which can then be used to determine the efficiency of solar heat reflecting paints.
The procedure is applicable to products intended for use in aerospace applications.

The purpose of the proposed Standard is to summarise the (general) corrosion protection requirements applicable to the materials, surface treatments, finishing and manufacturing processes used for space flight hardware.
It contains the minimum requirements necessary to guarantee and verify the suitability of materials, coatings systems and processes for corrosion control of space rated products.
The Standard classifies the corrosion environments and requires the issuing of a Corrosion Prevention and Control Plan based on the identified environmental classes. Testing and acceptance criteria are specified for each environmental class.
The scope of the document would include all flight parts and components used for space missions including Ground Support Equipment (GSE), where the materials and processes used in interfacing ground support equipment, test equipment, hardware processing equipment, hardware packaging and hardware shipment are to be controlled in order to prevent damage to or contamination of flight hardware.

This Standard details a test in which pressure‐sensitive tapes are used to assess
the suitability of, for example, coatings, paints, films and other thin materials,
proposed for use on spacecraft and associated equipment.
Surface coatings, such as thermal control paints and corrosion protection
coatings, are affected, both on the ground and after launch, by exposure to the
environment.
It is therefore important that the adhesion of the coating to the relevant
substrate remains at an acceptable level after exposure to the relevant
environmental condition.
The following materials and assemblies are covered by this test method:
 organic coating, e.g. varnishes, paints and plastic films;
 metallic finishes on, for example, printed circuit boards, second‐surface
mirrors, thermal radiators, plastic films;
 adhesive layers;
 composite thin films;
 small assemblies, e.g. solar cells having attached glass covers.
This standard may be tailored for the specific characteristics and constrains of a
space project in conformance with ECSS‐S‐ST‐00.
