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.

Source:

Opportunity Costs
This is defined as the value of the next-best choice available when choosing between several mutually exclusive choices (e.g., the decision to expand a facility may result in losing the opportunity to invest the maintenance funds in the financial markets). Opportunity costs are often excluded from estimates of fixed operation costs because they can be difficult for comparative analyses in the overall decision process. (TR66)

Moisture Content of Wood
The moisture content of wood is calculated by the following formula: Moisture content = (Mg-Mod)/Mod. Where Mg is the green mass of the wood and Mod is its oven-dry mass (the attainment of constant mass generally after drying in an oven set at 103 ± 2 °C for 24h). The equation can also be expressed as a fraction of the mass of the water and the mass of the oven-dry wood rather than a percentage. For example, 0.59 kg/kg (oven-dry basis) expresses the same moisture content as 59% (oven-dry basis). (TR55)

Meaningful Disruption
A meaningful disruption is a change in production that is reasonably likely to lead to a reduction in the supply of a drug by a manufacturer that is more than negligible and affects the ability of the manufacturer to fill orders or meet expected demand for its product. A meaningful disruption is not an interruption in manufacturing due to matters such as routine maintenance and does not include insignificant changes in manufacturing so long as the manufacturer expects to resume operations in a short period of time.
