Abstract This project was supplied by the Ministry of Defence who required that the acceptance criteria of two of their defence standards to be identified when compared to their British standards counterparts. Once this comparison had been identified it was then necessary to create two separate annexes, one for each topic, that was to be used within each defence standards counterpart. The two military defence standards represented by the MoD cover Non-destructive Testing methods which are known as radiographic and magnetic particle. Included within this passage will be a literature review, this in turn will highlight the nature of standards and their importance within civilian and military life. Also provided within this document is a background on the MoD’s standardization management policy, these guidelines were referred to during this full paper. This policy is the backbone of the standardization creation process for the MoD which was crucial to be referenced to as the interoperability of this research and finalised annex is as important as the information included within. The results of the critical analysis of the acceptance criteria between both MoD standards and their relevant BS EN ISO standards was then discussed. This discussion highlighted the analytical procedures used to find this information and therefore what this information comprised of. Finally, the value of this research is then discussed with regards to the useability of the created annexes as to whether the BS EN ISO documents would be considered to be at a high enough standard to be adopted by the MoD with a focus on the advantages and disadvantages of this. From the provided results a conclusion can be based that the use of integrated acceptance criteria via annex towards the BS EN ISO standard
