1.1 This guide establishes a process for the verification of application software used to calculate the mechanical properties of materials.1.2 This guide has two purposes: (1) it provides guidelines for creating standard data sets for verifying computer-generated test results, and (2) it describes how users can verify whether the calculations in their application software produce accurate, acceptable results. This does not ensure that the software will produce correct results in all cases. The verification is only for those conditions covered by the standard data sets. This guide uses the concept of standard “data sets,” which are made available by the ASTM groups responsible for each of the individual standards.1.3 This guide defines the terminology, the format, and the process for the use of these data sets and how the data sets are to be used for verification. It does not define the specific data sets required to verify each of the application standards. Rather, such data sets would become a necessary part of the standard and would be classified as an adjunct in accord with the definition in section B29 of the “Form and Style for ASTM Standards.” This classifies an adjunct as any material that is required for use of the standard but is not practicable to publish as an integral part of the standard.1.4 In Annex A1 there is an example of how such data sets would be made available for one example standard.1.5 Because the verification data sets are contained in files supplied to the application software in the computer, this procedure only provides verification of post-test calculations performed by the computer system. It does not evaluate the data acquisition system, real-time calculations, or any other part of the software beyond the post-test calculations.1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

2.1 Commercially available computer material management programs are being used regularly in the rubber industry. These programs typically will retrieve information from a raw material or compounding material data base by chemical name, CAS registry number, trade name, and supplier name. Retrieving information by these fields can present problems. The common chemical names are not standardized. IUPAC nomenclature is standardized but the names typically are too lengthy for easy retrieval. Also, the user may not have information such as trade name, supplier name, or CAS registry number.2.2 An alternate method of retrieving information from a raw material or compounding material data base is to sort by classification. This has the added advantage of enabling a compounder to select a compounding material from a given classification for a new compound formulation.1.1 This classification is intended to establish a method to find compounding materials on a computer data base by both functional and chemical classification. This classification will include rubber compounding materials or ingredients normally used in formulating rubber compounds. This classification is not intended for use in rubber latex or solvent based rubber adhesive applications.1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

The purpose of this practice is to describe techniques and procedures for computer forensics in regard to evidence handling, computers, digital imaging, and forensic analysis and examination.The examiner should be trained in accordance with Guide E2678.Individuals not trained in proper digital evidence procedures should consult with an appropriate specialist before proceeding.When dealing with technology outside your area of expertise, consult with an appropriate specialist before proceeding.1.1 This practice describes techniques and procedures for computer forensics within the context of a criminal investigation.1.1.1 This practice can be applicable to civil litigation.1.2 This practice describes seizing possible evidence, proper evidence handling, digital imaging, forensic analysis/examination, evidence-handling documentation, and reporting.1.3 This practice is not all inclusive and does not contain information relative to specific operating systems or forensic tools.1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
