In the machine shop this means without deviation. A blueprint may call out a dimension of 1.125 +/- .005. In this case 1.125 is the nominal dimension and +/- .005 is tolerance applied to it.
voltages – A single value of voltage falling within an allowable operating range, e.g., 120 volts as opposed to the range of 102 to 138 volts.
Usually refers to the Inside diameter of trade sizes of copper pipe and some CPVC pipes. Not for Iron Pipe connections. For example, a 1Ú2" NOM Comp. Fitting is actually 5/8" because 1Ú2" pipe has an OD of 5/8".
Objective for a specified parameter...may not be the actual value measured.
A descriptor applied to a dimension representing the center of the range of tolerance or a value if no tolerance is applied.
being value in terms of specification on currency or stock certificates rather than purchasing power; "nominal or face value"
value: classified value whose scale of measurement is not ordered (cf. ordinal value), i.e., the order of the classes is arbitrary and therefore not meaningful.
In home audio there are two main uses of this term: 1. nominal power rating- minimum amount of power recommended for a speaker. 2. nominal impedance- theoretically the minimum impedance a speaker will present to the amplifier.
the measurement value given to a board's width and depth that does not represent the actual measurements eg. a 2" x 4" is the nominal while 1 3/4" x 3 3/4" is the actual
The scale of measurement in which data are sorted into categories.
Level of measurement at which numbers, if used, are mere labels for discrete categories.
Some tube and pipe is called a fractional nominal size but does not actually measure this exact size. This is not cheating but it can be confusing. Typically the actual pipe measurement is larger than the nominal pipe size. Charts are available if you just have to know about pipe sizes.
The "rounded" dimension number used in a cabinet order code. Actual dimension may differ by a fraction either greater or smaller.
means small payment, or value.
The amount established by the issuer as the unit price of an asset; the main use of the nominal (face) value is as a reference for coupon payments. In the case of Bonos and Obligaciones, the nominal value is equal to the redemption value.
Describes output size, usually denoting that at least 90% of output is smaller than size indicated.
Usually refers to pipe sizes up to and including 12 inch. Also used in reference to wall thickness, generally as a "mean" or average measurement.
A nominal measurement is an approximate measurement; the actual measurement may vary slightly.
The value at which a system is designed to assure optimal operation. Tolerance considers the "normal" deviation of variable factors.
The original or stated value. Could be an output level, an impedance or any of several different measurements.
The dimensions of a piece of wood before it is finally milled. For example, a 2 x 4 starts out as a two inch by four inch piece of lumber, and when finished measures 1 1/2 inches by 3 1/2 inches.
(a) Being such in name only. (b) A measurement at a point in time, the value of which relates to that point of time only.
Name or identifying value of a measurable property by which a conductor or component or property of a conductor is identified, and to which tolerances are applied.
pipe size or wall thickness as specified (not actual). Sizes refer to approximate ID, even though OD is the fixed dimension.
The exact (or ideal) intended value for a specified parameter. Tolerances are specified as positive and negative deviations from this value.
Measured in the dollar value (as in nominal output, income, or wage rate) or in market terms (as in nominal exchange or interest rate) of the period under consideration. Compare with real.
A measure based on current-dollar value. For income or spending, the nominal level is measured in current dollars. See current dollar; compare with real.
(1) Stated values, for instance, nominal dimensions. (2) The settings of a pulse generator's programmable parameters as shipped. Nominal values may also be used to describe those programmable pacing parameter values which will safely pace the majority of patients. Also known as shipped settings.
A close approximation of actual size (for example, 2x4 is a nominal designation for a section of lumber that actually measures approximately 1 1/2 x 3 1/2 inches).
A level of measurement at which only subjective information is available about a feature. For a point, for example, the name of the place.
Small payment, or value Nominal Capital. Total face value of authorised issuable capital.
Often defined as the actual size of lumber before dressing or finishing.
A nominal rate or nominal yield is also the annual interest that would be earned from a fixed income investment if the security were purchased at par value. Actual rate of return is usually different. It is same as coupon rate.
A rounded-off stated size. The nominal size is the closest rounded-off size.
