This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

Vacuum Cleaners
This standard is issued under the fixed designation F395; the number immediately following the designation indicates the year of original
adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript
epsilon (´) indicates an editorial change since the last revision or reapproval.
agitator, n—a device that is in contact with the surface to be cleaned and assists in dirt removal by mechanical action, rotary and
otherwise.
air power (AP, W), n—(1)(1) in a vacuum cleaner, the net time rate of work performed by an air stream while expending energy
to produce an airflow by a vacuum cleaner under specified air resistance conditions. (2)(2) a measure of the ability of the air
stream to do work. Air power is expressed in terms of air watts.
canister vacuum cleaner, n—a portable floor-supported vacuum cleaner, having a nozzle separated from the cleaner housing by
a hose and designed for normal-duty cleaning of household dirt. In use, only the nozzle is guided over the surface area to be
cleaned. The cleaner may have detachable nozzles, attachments, and wands for both floor and above-the-floor cleaning. The
nozzle may employ a driven agitator to assist in cleaning.
carpet lay, n—orientation of the pile of a carpet (or fabric) relative to the backing; the tendency of a carpet’s pile to lean uniformly
in a specific direction relative to the backing.
car vacuum cleaner, n—a relatively small, lightweight, portable cleaner that is designed for operation from a d-c power source,
generally a 12-V automotive battery (see also hand-held vacuum cleaner).
central vacuum cleaning system, n—a cleaning system consisting of a stationary vacuum producer and dust collector that
incorporates the use of a tubing system internal to a building structure and a flexible hose, or both, for conveying dust from the
area being cleaned to the dust collector. The system is designed for all-purpose cleaning including various types of larger debris
and may be designed for liquid pickup. The system is used by inserting one end of a hose into a wall vacuum inlet valve and
attaching a cleaning nozzle to the other end. In use, the nozzle is guided over the surface area to be cleaned. The system may
contain a driven agitator to assist in dirt removal and it normally has detachable nozzles, attachments, and wands for both floor
and above-the-floor cleaning.
cleaning ability, dry, n—the potential of a vacuum cleaner to remove dirt from a surface (sometimes referred to in the industry
as cleanability, dry).
cleaning effectiveness, dry, n—the ratio of the quantity of dirt removed to the quantity of dirt distributed on a test area.
cleaning tool, n—a customer-installed device for a vacuum cleaner that is applied to the surface to be cleaned and is attached to
the hose or the nozzle, for specialty cleaning functions.
combination vacuum cleaner, n—a canister vacuum cleaner having a motorized nozzle separated from the cleaner housing but
connected to it by means of a hose or hose and wand.
commercial vacuum cleaner, n—a vacuum cleaner suitable for the heavy-duty and sometimes continuous cleaning tasks
encountered in establishments such as hotels, motels, office buildings, churches, clubs, etc.
corrected air flow, n—the volume of air movement per unit of time under standard atmospheric conditions. The flow is expressed
in cubic feet per minute or litres per second.
dirt receptacle first vacuum cleaner system, n—a vacuum cleaner construction in which the dirt laden air is passed through a
dirt receptacle (bag type filter, bagless filter, or other type of dirt separator). The separated air is then pulled through the fan
(bypass) or fan and motor (flow through) and expelled from the cleaner. This type of construction is sometimes referred to as
clean air or indirect system.
