  • Accelerated Testing

    (ICH Q1A (R2)) Studies designed to increase the rate of chemical degradation or physical change of a drug substance or drug product by using exaggerated storage conditions as part of the formal stability studies. Data from these studies, in addition to long term stability studies, can be used to assess longer term chemical effects at non-accelerated conditions and to evaluate the effect of short term excursions outside the label storage conditions such as might occur during shipping. Results from accelerated testing studies are not always predictive of physical changes.
  • Acceptable Daily Exposure (ADE)

    A dose that is unlikely to cause an adverse effect in an individual if exposed, by any route, at or below this dose every day for a lifetime. By definition The ADE is protective of all populations by all routes of administration. Normally, the ADE should be based on studies using the same route that it will be applied to evaluate. When this is not possible, and an ADE is required, proper professional should be engaged (toxicologists) to provide a sound scientific rationale to support application to a different route. Only then can the ADE be adjusted to extrapolate between routes which may result in a lower or higher value. As additional information becomes available, the ADE value should be reviewed and revised if necessary.
  • Acceptable Exposure

    Results of repeated environmental and/or biological monitoring studies showing no levels above established action levels.
  • Acceptance Criteria

    (ICH Q6B) Numerical limits, ranges or other suitable measures for acceptance of the results of analytical procedures which the drug substance or drug product or materials at other stages of their manufacture should meet.
  • Acceptance Criteria

    The predetermined result of a specified test.
  • Acceptance Criteria

    Measurable terms under which a test result may be considered acceptable.
  • Acceptance Criteria

    The criteria a product must meet to successfully complete a test phase or to achieve delivery requirements. This is usually associated with a performance qualification. It may require an exact result (such as the ability of a bar code system to identify correct or incorrect codes) or it may state an acceptable range (such as an incubator demonstrating the ability to maintain a temperature set point plus or minus a given tolerance).
  • Acceptance Criteria

    (IEEE) (ASTM E 2500) The criteria that a system or component must satisfy in order to be accepted by a user, customer or other authorized entity.
  • Acceptance Criteria

    (ICH Q7) Numerical limits, ranges, or other suitable measures for acceptance of test results
  • Acceptance Criteria

    The limits of conditions of room critical parameters that may affect the product quality. These conditions may include temperature, humidity, and room air quality. For example, if humidity or particulates are not critical parameters affecting product quality they are not included in acceptance criteria.
  • Acceptance Criteria

    (ICH Q6A) Numerical limits, ranges, or other suitable measures for acceptance of the results of analytical procedures.
  • Acceptance Criteria

    The criteria a product must meet to successfully complete a test phase or to achieve delivery requirements.
  • Acceptance Criteria

    (ASTM/PAT) Numerical limits, ranges, process signatures, or other suitable measures that are necessary for making a decision to accept or reject the results of a process, in-process variable, a product or any other convenient subgroups or manufactured units.
  • Acceptance Test

    (IEEE) Testing conducted to determine whether or not a system satisfies its acceptance criteria and to enable the customer to determine whether or not to accept the system.
  • Accepteur du contrat (Contract acceptor)

  • Acceptor Control

    The regulation of the rate of respiration by the availability of ADP (Adenosine Diophosphate) as phosphate acceptor.
  • Acceptor Junction Site

    The junction between the right 3' end of an intron and the left end of an exon
  • Access

    (ANSI) To obtain the use of a resource
  • Access Device

    Device for manipulation of processes, tools, or products within the separative device.
  • Access Floor System

    An assembly consisting of panels mounted on pedestals to provide an under-floor space for the installation of mechanical, electrical, communication, or similar systems or to serve as an air-supply or return-air plenum.
  • Access Time

    (ISO) The time interval between the instant at which a call for data is initiated and the instant at which the delivery of the data is completed.
  • Accession

    The addition of germplasm deposits to existing germplasm storage banks.
  • Accident

  • Accidental Release

    The unintentional discharge of a microbiological agent (i.e., microorganism or virus) or eukaryotic cell due to a failure in the containment system. Accidental releases may be de minimis in nature.
  • Acclimatization

    The biological process whereby an organism adapts to a new environment. One example is the process of developing microorganisms that degrade toxic wastes in the environment.
