The Aim and Objective of these Guidelines
The object of this document is to determine ISO requirements for the Firearms and Toolmark community, which no only meet the ASCLD/LAB requirements but exceed them. The result should be standard supporting the discovery of new and relevant information. Until the previous decade, researchers looking into organizations depended exclusively on an arrangement of self-control in light of shared moral standards and for the most part relied on research practices to guarantee trustworthiness in all their testing. Among those unwritten rules and guidelines researchers, and also numerous different laboratories, are those that communicated the trustworthiness of information, theses, assertions or any other documents.
ISO Requirements, Guidelines and Applications
If an experiment is expected to or based on uncertain factors, it is legitimate to work with the results, although they don’t meet the objective and requirements of the ISO requirements and guidelines. To assure that experiments can be reproduced correctly, factors that might influence fluctuating results should be documented and noted thoroughly. Only that way future test results can be analyzed correctly. Examples might be technical errors, manufacturing errors or anything related.If experiments are based on or include other work those should be fully documented and disclosed, especially if those are required to interpret the results correctly. To assure those mistakes are as rare as possible every examiner could reproduce a certain measurements independently. The results could be compared and used to calculate how much of a discrepancy should be expected. The more often a certain experiment is performed the more accurate those discrepancy can be determined.
No matter what sources or reference collections are being used the laboratory should control and uniquely identify them. Since there are a certain range of instruments that need to be calibrated correctly to work properly, for instance any form of rulers, microscopes and chronographs, imprecise measurements can occur if not acquired multiple times. Imprecise measurements of projectile velocity, barrel length and size of firearms as well as ammunition or those that can be found in the range of legal/ regulatory standards should only be considered if they were tested a certain amount of times to avoid failures. Since opinions and comments are valued in the community, the ISO requirements include certain guidelines regarding the documentation of such. Interpretations and opinions should be clearly stated as such and marked, so they can be identified. Furthermore the laboratory should note down on which sources or conclusions those opinions are based. The customer should be notified prior to handing over the report, that said document contains and is only complete with the opinions and interpretations listed inside and it’s up to the laboratory how they do it.
Since almost every laboratory works with some sort of consumables (gun supplies, microscopes, rectiles, rifle scopes) it is only naturally that those must be obtained by third-party suppliers. Those suppliers should meet certain quality standards and should be documented. Segments of ammo reference accumulations might be traceable by the parcel number on the ammo boxes, the head stamp, or the recipes. In addition to the consumables listed above those might include firearms and ammunition boxes, as well as gun accessories.
The team should have a high level of commitment and understanding on what exactly the laboratory works on. To maintain certain quality standards appropriate communication is essential in any form of laboratory or scientific working group. All facts stated are above not more than our opinion on this exact topic. Those guidelines are a suggestion that might work for a certain laboratory but might not for another. There many different factors that come into play which we might not have included.
