DRCheat is intended to provide convenient reference material, calculation tools, and other resources for nondestructive testing (NDT) professionals and students. The information and tools provided by DRCheat are intended to assist users and are not a substitute for applicable standards, specifications, procedures, manufacturer instructions, training, certification requirements, or professional judgment.
Users should independently verify information provided by DRCheat before relying on it for professional work. Reference sheets, formulas, conversions, calculations, examples, and other materials may contain errors, omissions, outdated information, or other inaccuracies.
Applicable codes, standards, specifications, procedures, and other controlling documents should always take precedence over information provided by DRCheat.
DRCheat's calculators and other computational tools are provided as convenience tools. Results should be independently checked before being used in inspection, testing, reporting, engineering, safety, or other professional decisions.
A calculation produced by DRCheat should not be treated as automatically correct simply because it was generated by the software. Users are responsible for confirming inputs, units, formulas, assumptions, and results.
Some DRCheat features may use artificial intelligence or machine-learning technology. AI-generated responses and information can be incomplete, inaccurate, outdated, or misleading, and may produce plausible-sounding information that is incorrect.
Do not blindly trust AI-generated information. AI output should be independently reviewed and verified against reliable sources and applicable NDT standards, procedures, and specifications before being used for professional purposes.
AI-assisted features are intended to provide assistance and information, not to replace qualified personnel or professional judgment.
The user remains responsible for determining whether information, calculations, or recommendations provided by DRCheat are appropriate for their particular situation.
DRCheat does not determine whether an inspection, indication, calculation, or test result is acceptable. Users are responsible for following the applicable requirements for the work being performed and for making the final professional determination.
While reasonable efforts may be made to maintain the accuracy and usefulness of DRCheat, no guarantee is made that all information, calculations, references, or AI-generated content will always be complete, current, or error-free.
Use of DRCheat does not eliminate the need to consult the applicable governing documents, qualified personnel, or other authoritative sources.
By using DRCheat, you acknowledge that you are responsible for independently verifying information and results before relying on them.
