Direct answer: Laboratory records should separately document the approved instruction, observed conditions, timestamps and deviations.
Which instruction controls?
Only an approved source for the exact material and format can establish a product-specific storage condition. General practice cannot replace that source.
Which conditions should be recorded?
Records may include time, observed temperature, light protection, container state and documented deviations where relevant to the approved instruction.
What should not be assumed?
Without a product-specific source, no temperature, shelf life, transport condition or stability period is asserted.
Example: keep a traceable laboratory record
A hypothetical storage log can pair the approved product-specific instruction with observed conditions, dates and any deviation. It should not invent a temperature or shelf life when the exact material has no approved instruction. That distinction keeps a general record-keeping example separate from a claim about a Define product.
Which sources frame interpretation?
The following regulatory sources explain general analytical-procedure concepts. They are not product reports and are not evidence of Define testing.
