Test targets where the percentage of area coverage has been predetermined are not readily available from commercial sources. Moreover, it is beyond the ability of most users to verify if indeed, the commercially-available test targets contain the advertised area coverage. This procedure allows the user to easily create test targets, using commercially available PC software, which can be easily verified for percentage of area coverage and can provide reproducible interlaboratory results.1.1 This practice describes a method for creating test targets containing varying percentages of area coverage for use in determining the yield of the supplies used by liquid and solid ink jet printers. 1.2 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 This standard may involve hazardous materials, operations and equipment. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine limitations prior to use.

This European Telecommunication Standard (ETS) specifies the technical characteristics required for end-to-end interworking over the Public Switched Telephone Network (PSTN) of 14400, 12000, 9600, 7200 and 4800 bit/s duplex modems standardized for use over the PSTN, in accordance with CCITT Recommendation V.32 bis [1].
Public Switched Telephone Network (PSTN) - Category II specification for 14400, 12000, 9600, 7200 and 4800 bits per second duplex modems standardized for use on the PSTN
This ETS contains the technical characteristics required for end-to-end interworking over the Public Switched Telephone Network (PSTN) of 2400 bits per second (bit/s) duplex modems standardized for use over the PSTN, in accordance with CCITT Recommendation V.22bis [2]. The term ""modem"" in the context of this ETS includes all physical implementation practices for voice band modem, which is conductively connected to the PSTN.
Public Switched Telephone Network (PSTN) - Category II specification for 2400 bits per second duplex modems standardized for use on the PSTN
This ETS contains the technical characteristics required for end-to-end interworking over the Public Switched Telephone Network (PSTN) of 1200 bits per second (bit/s) duplex modems standardized for use over the PSTN, in accordance with CCITT Recommendation V.22 [1]. NOTE: CCITT Recommendation V.22 [1] also describes a method of transmitting data at 600 bit/s. This ETS specifies the characteristics to be met by such modems and, if requested by the applicant, this feature can also be tested against the specifications.
Public Switched Telephone Network (PSTN) - Category II specification for 1200 bits per second duplex modems standardized for use on the PSTN
This ETS contains the technical characteristics required for end-to-end interworking over the Public Switched Telephone Network (PSTN) of modems supporting: - half duplex operation over the PSTN at 1200 bit/s, and or - asymmetrical duplex operation over the PSTN at 1200/75 bit/s standardized for use over the PSTN, in accordance with CCITT Recommendation V.23 [3].
Public Switched Telephone Network (PSTN) - Category II specification for 1200 bits per second half duplex and 1200/75 bits per second asymmetrical duplex modems standardized for use on the PSTN
This second edition European Telecommunication Standard (ETS) contains the technical characteristics required for end-to-end interworking over the Public Switched Telephone Network (PSTN). Clauses of this ETS also contain Category II specifications defined for certain features which may be provided by some modems, but the requirements in these parts are only applicable when invoked by a modem specific ETS.
Public Switched Telephone Network (PSTN) - Basic Category I and Category II specifications for modems standardized for use on the PSTN
This ETS specifies the technical characteristics required for end-to-end interworking over the Public Switched Telephone Network (PSTN) of 9600 bits or 4800 bits modems standardized for use over the PSTN, in accordance with CCITT Recommendation V.32 [2]. The objective of this specification, the application of which is entirely voluntary, is to provide the users with an added degree of assurance that modems in compliance with this specification can interwork with each other, under most network conditions.
Public Switched Telephone Network (PSTN) - Category II specification for 9600 or 4800 bits per second duplex modems standardized for use on the PSTN
The Videotex processable data facility specified in this ETS is intended to be used for data file transfer. These files may contain software or other file types. This ETS may be used to download files from the host to the terminal. It may also be used for transferring files between two end systems in both directions, all the operations then being performed under the control of one or the other system depending on a preliminary negotiation.
