ČSN EN 61189-5-2 IEC 61189 relates to test methods for materials or component robustness for printed board assemblies, irrespective of their method of manufacture. The standard is divided into separate parts, covering information for the designer and the test methodology engineer or technician. Each part has a specific focus; methods are grouped according to their application and numbered sequentially as they are developed and released. In some instances test methods developed by other TCs (for example, TC 104) have been reproduced from existing IEC standards in order to provide the reader with a comprehensive set of test methods. When this situation occurs, it will be noted on the specific test method; if the test method is reproduced with minor revisions, those paragraphs that are different are identified. This part of IEC 61189 contains test methods for evaluating robustness of materials or component for printed board assemblies. The methods are self-contained, with sufficient detail and description so as to achieve uniformity and reproducibility in the procedures and test methodologies. The tests shown in this standard are grouped according to the following principles: P: preparation/conditioning methods V: visual test methods D: dimensional test methods C: chemical test methods M: mechanical test methods E: electrical test methods N: environmental test methods X: miscellaneous test methods To facilitate reference to the tests, to retain consistency of presentation, and to provide for future expansion, each test is identified by a number (assigned sequentially) added to the prefix (group code) letter showing the group to which the test method belongs. The test method numbers have no significance with respect to an eventual test sequence; that responsibility rests with the relevant specification that calls for the method being performed. The relevant specification, in most instances, also describes pass/fail criteria. The letter and number combinations are for reference purposes to be used by the relevant specification. Thus "5-2C01" represents the first chemical test method described in IEC 61189-5-2. In short, in this example, 5-2 is the number of the part of IEC 61189, C is the group of methods, and 01 is the test number. This part of IEC 61189 focuses on test methods for soldering flux based on the existing IEC 61189-5 and IEC 61189-6. In addition, it includes test methods of soldering flux for lead free soldering.

ČSN EN 16602-70-53 This Standard describes a test protocol to determine the compatibility of materials, components, parts, and assemblies with sterilization processes. It is dedicated to test on non-flight hardware only. Any additional requirements that can be imposed by the potential use of test samples as flight hardware are not covered in this document (e.g. handling requirements). This Standard covers the following: - Identification of critical test parameters to establish functional integrity of the hardware. - Typical test protocols. - Acceptance criteria. Statements about compatibility of materials and components with sterilization processes in this document are made in general terms only. Other factors for determination of whether a material or component is suitable for a particular mission system application include: - The potential number of sterilization cycles to which the material/component will be subjected in their live cycle. - The additional stresses on materials/components introduced when they have become part of a larger unit/equipment/system undergoing sterilization. - Compatibility of sterilization processes at e.g. materials level. This compatibility does not automatically guarantee that it will perform to its requirements in an assembly. The final application and possible interactions at higher assembly level are important considerations for qualification. - Qualification of hardware achieved by specific sterilization parameters. They cannot be necessarily extrapolated to other sterilization parameters, not even within the same sterilization process. - The drift in performance that can be induced by sterilization processes . This drift can cause equipments to fail to meet their specified performance requirements, even though each individual element/component remains within spec. An example of this is where 'Select-on-test' components are used to operate a component over a critically narrow range its full performance. To assess ultimately the suitability/compatibility of a material or component for an application requires a full consideration of the impact of sterilization processes to which it is subjected during its whole life. This includes sterilization processes it undergoes from the time it is a standalone component/material right through to when it experiences final sterilization as part of the complete system. This standard may be tailored for the specific characteristic and constrains of a space project in conformance with ECSS-S-ST-00.

ČSN EN 16602-70-50 This standard defines the requirements and guidelines for the measurement of particulate contamination on the surfaces of spacecraft systems and those of the cleanrooms or other cleanliness controlled areas in which they reside. This includes the measurement of particulate contamination that is present on the spacecraft or cleanroom surfaces via the use of representative witness samples placed in the vicinity of the spacecraft hardware, the direct measurement of particulate contamination levels on surfaces of spacecraft hardware from the direct surface transfer to adhesive tape-lift samples and particulate contaminant levels within fluids used for the cleaning or rinsing of such spacecraft system components and cleanroom surfaces. This standard also defines the methods to be used for the visual inspection of spacecraft system hardware for particulate contamination. The measurement of airborne particulate contamination is not covered in this standard and ISO 14644 "Cleanrooms and associated controlled environments" is applicable in this case. This standard does not cover particulate contamination monitoring for spacecraft propulsion hardware which is covered in ECSS-E-ST-35-06. This standard may be tailored for the specific characteristic and constrains of a space project in conformance with ECSS-S-ST-00.
