PDA Technical Glossary
PDA Technical Reports are highly valued membership benefits because they offer expert guidance and opinions on important scientific and regulatory topics and are used as essential references by industry and regulatory authorities around the world. These reports include terms which explain the material and enhance the reader’s understanding.
The database presented here includes the glossary terms from all current technical reports. The database is searchable by keyword, topic, or by technical report. Each definition provided includes a link to the source technical report within the PDA Technical Report Portal.

Active Systems
Systems with active temperature control (e.g., air/sea freight containers, refrigerated trucks/cars). (TR39) System with active temperature control. It makes use of electricity or fuel for the compressor to maintain temperature. Examples include refrigerated trucks, temperature-controlled ocean containers, and active ULDs. (TR58) Actively powered system that uses electricity or other fuel source to maintain a temperaturecontrolled environment inside an insulated enclosure under thermostatic regulation (e.g., cold room, refrigerator, temperature-controlled truck, refrigerated ocean or air container). (TR64) (TR72) (Synonym: Active Temperature Controlled System)

Active Unit Load Device (Active ULD)
A Unit Load Device (ULD) container used to consolidate cargo on aircraft that contains electrical or battery-powered temperature control systems for transporting temperature-sensitive materials; an RKN type is used in an FMEA example. (TR58) A unit load device with an active heating and/or cooling system that is typically used in air transportation, usually operated from externally supplied AC or DC power or from internal batteries. (TR64)

Ambient Temperature
The air temperature of an environment. (TR58)
Source:
Cold Chain
A temperature- and time-controlled supply chain for products (e.g., refrigerated products typically have a temperature storage range of 2 °C to 8 °C). (TR58)
Source:
Deviation
Departure or digression from set parameters. (TR58)
Data or a result outside of the expected range or an unfulfilled requirement; it may be called nonconformity, defect, discrepancy, out-of-specification, out-of-limit, or adverse trend. (TR88)

Qualification
Documented testing that demonstrates with a high degree of assurance that a specific process will meet its pre-determined acceptance criteria. (TR39) (TR58) (TR64)

Quality Risk Management (QRM)
A systematic process for the assessment, control, communication, and review of risk to the quality of the drug product across the product lifecycle.(TR43)(TR54-2)(TR54-3)(TR57)(TR67)(TR68)
Documentation to prove that an installation/ equipment/process is designed and/or tested according to predefined specifications. Documentation may include Design Qualification (DQ), Installation Qualification (IQ), Operational Qualification (OQ) and Performance Qualification (PQ).(TR58)
A systematic process for the assessment, control, communication, and review of risks to the quality of the drug (medicinal) product across the product lifecycle.(TR 54-5)(TR 76)(TR88)

Residual Risk
Risk remaining after risk control measures have been taken. (TR44) (TR58)
Risk remaining after risk control measures have been implemented (derived from ISO 14971:2007). (TR54) (TR54-2)
Risk remaining after risk control measures has been implemented. (TR54-5)
