We measured the retardance introduced by the thin film, reporting the phase shift angle in degrees according to the Abelès and Mueller conventions.

Heavy snowfall was retarding the rescue team's progress through the mountains.

The retarding of the assembly line became a major bottleneck, forcing managers to revise the schedule.

The engineers discussed the system delays during the meeting.

The sudden storm retards the progress of the rescue team.

The curing process is retardable under lower temperatures, allowing technicians to extend working time before the material hardens.

The instrument measured several retardances across the sample, revealing unexpected anisotropy.

The forest service applied retardants along the fire line to protect the town.

The project suffered multiple retardments due to unexpected supply shortages, pushing back the completion date by months.

The retardancy of the new polymer was critical to meeting the building code's fire-safety requirements.
