What time restrictions apply to procurement of units for verification testing using the 4-unit, multiple-sample approach? Follow

For verification testing of non-lighting products, all four units of a model selected for testing must be procured at one time, per Directive 2011-04. In cases of non-lighting units that are selected from a manufacturer's warehouse, the units identified to supplement a spot check failure may be considered procured when they are tagged with tamper-proof packaging in the warehouse or other storage facility, provided that those units can be made available for testing at the verification testing laboratory within five business days after completion of the initial spot check.
