You can see the depreciation rates required by the U.S. Internal Revenue Service for U.S. income tax purposes by going to www.irs.gov. Perhaps you would find their publication on Depreciation to be helpful.
For financial reporting (not income tax reporting), it is a professional judgement of the depreciation rate that best matches the depreciation expense to the revenues earned. Hence, I am not certain you will find standard depreciation rates for financial reporting.
