Permission; granting, conceding, or admitting

Diminution in the physiological response to a drug that occurs after continued use, necessitating larger doses to produce a given response.

Acknowledgment.

The ability to digest or metabolize a food, drug, or other substance or compound

An amount, portion, or share that is allotted or granted; a sum granted as a reimbursement, a bounty, or as appropriate for any purpose

Acceptance of a tissue graft or transplant without immunological rejection.

Abatement; deduction; the taking into account of mitigating circumstances

Unresponsiveness to an antigen that normally produces an immunologic reaction.

(commerce) A customary deduction from the gross weight of goods, differing by country.

The ability of an organism to resist or survive infection by a parasitic or pathogenic organism.

(horse racing) A permitted reduction in the weight that a racehorse must carry.

The ability to endure pain or hardship; endurance.

A child's allowance; pocket money.

(uncountable) The ability or practice of tolerating; an acceptance of or patience with the beliefs, opinions or practices of others; a lack of bigotry.

(minting) A permissible deviation in the fineness and weight of coins, owing to the difficulty in securing exact conformity to the standard prescribed by law.

(uncountable) The ability of the body (or other organism) to resist the action of a poison, to cope with a dangerous drug or to survive infection by an organism.

(obsolete) Approval; approbation.

(countable) The variation or deviation from a standard, especially the maximum permitted variation in an engineering measurement.

(obsolete) License; indulgence.

(uncountable) The ability of the body to accept a tissue graft without rejection.

(engineering) A planned deviation between an exact dimension and a nominal or theoretical dimension.

The power or capacity of enduring; the act of enduring; endurance.

(transitive) To put upon a fixed allowance (especially of provisions and drink).

The endurance of the presence or actions of objectionable persons, or of the expression of offensive opinions; toleration.

(transitive) To supply in a fixed and limited quantity.

The power possessed or acquired by some persons of bearing doses of medicine which in ordinary cases would prove injurious or fatal.

Approval; approbation.

Capability of growth in more or less shade.

The act of allowing, granting, conceding, or admitting; authorization; permission; sanction; tolerance.

The allowed amount of variation from the standard or from exact conformity to the specified dimensions, weight, hardness, voltage etc., in various mechanical or electrical devices or operations; - caklled also allowance

Acknowledgment.

The capacity to resist the deleterious action of a chemical agent normally harmful to the organism; as, the acquired tolerance of bacteria to anitbiotics.

License; indulgence.

The acquired inability to respond with an immune reaction to an antigen to which the organism normally responds; - called also immunotolerance, immunological tolerance, or immune tolerance. Such tolerance may be induced by exposing an animal to the antigen at a very early stage of life, prior to maturation of the immune system, or, in adults, by exposing the animal to repeated low doses of a weak protein antigen (low-zone tolerance), or to a large amount of an antigen (high-zone tolerance).

That which is allowed; a share or portion allotted or granted; a sum granted as a reimbursement, a bounty, or as appropriate for any purpose; a stated quantity, as of food or drink; hence, a limited quantity of meat and drink, when provisions fall short.

The power or capacity of an organism to tolerate unfavorable environmental conditions

Abatement; deduction; the taking into account of mitigating circumstances; as, to make allowance for the inexperience of youth.

A disposition to allow freedom of choice and behavior

A customary deduction from the gross weight of goods, different in different countries, such as tare and tret.

The act of tolerating something

To put upon a fixed allowance (esp. of provisions and drink); to supply in a fixed and limited quantity; as, the captain was obliged to allowance his crew; our provisions were allowanced.

Willingness to recognize and respect the beliefs or practices of others

An amount allowed or granted (as during a given period);

A permissible difference; allowing some freedom to move within limits

A sum granted as reimbursement for expenses

An amount added or deducted on the basis of qualifying circumstances;

A permissible difference; allowing some freedom to move within limits

A reserve fund created by a charge against profits in order to provide for changes in the value of a company's assets

The act of allowing;

Put on a fixed allowance, as of food

Allowance is the planned difference between the dimensions of mating parts, influencing the ease of assembly and the type of fit.

Tolerances are crucial for ensuring that parts fit and function together as intended, even when there are minor deviations in size.

Yes, an allowance can be designed to create a loose fit, allowing for easy assembly or operational movement between parts.

Tighter tolerances require more precise manufacturing processes, often leading to higher costs.

Tolerance levels are monitored in quality control to ensure parts meet specified dimensional criteria.

Adjustments to allowances typically require design changes and may involve retooling or remanufacturing parts.

Tolerance is the allowable variation in a part's dimensions, ensuring it can function correctly within a range.

No, allowance can be negative in cases like interference fits, where parts must be forced together.

Yes, tighter tolerances generally improve product quality by ensuring parts fit and function more precisely.

Designers consider factors like the intended fit, operational conditions, and manufacturing capabilities when deciding on allowances.

Environmental factors like temperature and humidity can cause material expansion or contraction, influencing the effectiveness of tolerances and allowances.

Tolerance affects how closely parts can fit together, with tighter tolerances allowing for more precise fits, whether clearance or interference.

Yes, allowances can reduce the need for tight tolerances and thus decrease the necessity for extensive post-production finishing processes.

Yes, allowances can be designed to accommodate thermal expansion, preventing part failure or distortion.

No, tolerance requirements vary significantly across industries, with some sectors like aerospace demanding extremely tight tolerances.
