  • Teratogen

    An agent, such as a virus, a drug, or radiation, that causes malformation of an embryo or a fetus and birth defects in children (liveborn offspring).
  • Teratogenicity

    (ICH Q3C (R4)) The occurrence of structural malformations in a developing fetus when a substance is administered during pregnancy.
  • Terminal

    A device, usually equipped with a CRT display and keyboard, used to send and receive information to and from a computer via a communication channel.
  • Terminal Filter

    HVAC air filtration located at the entry point of air supply to the room (usually at the ceiling).
  • Terminal Sterilization

    The process applied to product sealed in its final container that transforms a non-sterile product into a sterile one.
  • Terminal Sterilization

    This term is a gross misnomer because it refers specifically to the terminal heat sterilization of LVPs usually by steam.
  • Terminally Ill

    For an individual, it means that the subject has a life expectancy of six months or less as stated in writing by his or her attending physician and surgeon.
  • Terminator (of transcription)

    A DNA sequence just downstream of the coding segment of a gene, which is recognized by RNA polymerase as a signal to stop synthesizing mRNA. In prokaryotes, terminators usually have an inverted repeat followed by a short stretch of Us at the very end of the transcribed portion. There may also be sequences beyond the transcribed part of the gene which influence the termination of transcription.
  • Tertiary Structure

    The total three-dimensional shape of a protein that is essential to protein function.
  • TES

    Thermoplastic Elastomer, Styrenic
  • Test

    (ISO) Determination of one or more characteristics according to a procedure.
  • Test

    (IEEE) An activity in which a system or component is executed under specified conditions, the results are observed or recorded, and an evaluation is made of some aspect of the system or component.
  • Test

    Procedure undertaken in accordance with a defined method to determine the performance of an installation or an element thereof. ISO 14644-2.
  • Test (IEEE) (1), (ISO) (2)

  • Test (IEEE) (1), (ISO)(2)

  • Test Aerosol

    Gaseous suspension of solid and/or liquid particles with known and controlled size distribution and concentration. ISO 14644-3.
  • Test Aerosol Generator

    Equipment, capable of generating particulate matter having appropriate size range (e.g. 0,05µm to 2µm) at a constant concentration, which may be produced by thermal, hydraulic, pneumatic, acoustic, or electrostatic means.
  • Test Case

    (IEEE) Documentation specifying inputs, predicted results, and a set of execution conditions for a test item. Synonymous: Test Case Specification.
  • Test Case

    (IEEE) A set of test inputs, execution conditions, and expected results developed for a particular objective, such as to exercise a particular program path or to verify compliance with a specific requirement.
  • Test Case Generator

    (IEEE) A software tool that accepts as input source code, test criteria, specifications, or data structure definitions; uses these inputs to generate test input data; and, sometimes, determines expected results. Synonymous: Test Data Generator, Test Generator.
  • Test Case Specification

  • Test Cycle

    A defined period and frequency for the identification, measurement, and evaluation of a material, product, system, or service that produces a test result.
  • Test Cycle

    A single full operation.
  • Test Design

    (IEEE) Documentation specifying the details of the test approach for a software feature or combination of software features and identifying the associated tests.
  • Test Documentation

    (IEEE) Documentation describing plans for, or results of, the testing of a system or component. Types include test case specification, test incident report, test log, test plan, test procedure, test report.
