2、ication Code) 40 1310 GOST 16325-88 Date of Introduction 01.07.89 Failure to comply with this Standard will result in legal proceedings This Standard applies to stationary general-purpose digital computers (hereinafter referred to as computers) intended for independent operation as well as operation
3、 in data processing systems, and establishes the requirements for them. This Standard does not apply to specialized computers. The devices that are included into the computer structure shall comply with GOST 21552- 84, taking into consideration the requirements of this Standard. The terms and explan
4、ation of concepts used in this Standard are specified in Appendix 1. The premises intended for the use of computers shall comply with conditions specified in Appendix 2. 1. PURPOSE REQUIREMENTS 1.1. Requirement s for technical efficiency General-purpose computers are subdivided into classes (specifi
5、ed in table 1) in terms of throughput with the corresponding RAM capacity. Official EditionReprinting is prohibited !

A computer designed as a part of a unified series (family) (which is defined in its statement of work) shall ensure: computer program compatibility from below upwards (from computers with lower throughput to computers with higher throughput); un
10、ified input-output interface: unified interface for power supply; unified design principles; unified data structures. GOST 16325-88 p. 3 1.4. Compatibility of computers intended for computer system building, requirements for round-the-clock and/or shift computer operation, for symbols, codes, units
11、and data formats, shall comply with GOST 21552-84. 1.5. Requirement for software. The computer software shall comprise: an operating system (OS) and programs for extension of OS possibilities, ensuring the ability to carry out the requirements of clause 1.2 and databank building; programming means,
12、including compilers from unified programming languages; test software; general-purpose application programs. 2. RELIABILITY REQUIREMENTS 2.1. The computer reliability indicators and their numerical values shall be specified in the statement of work and specifications from those specified in this Sec
13、tion. The procedure for specifying the numerical values for the computer reliability indicators is specified in Appendix 4. 2.2. The values of reliability indicators (except for the average shelf life) shall be specified for normal climatic operating conditions. 2.3. The values of mean time to failu
14、re (Tf) * shall not be less than 750 hrs from 01.07.89, 1 000 hrs from 01.01.91, and 2 000 hrs from 01.01.93, for computers of classes 3 to 5; 500 hrs from 01.07.89 for computers of class 6. 2.4. The values of mean time to malfunction (Tm) shall be specified in the statement of work and the specific
15、ations for a specific computer. N otes to clauses 2.3 and 2.4: 1. Switching the failed technical facility of the computer onto a facility of the same type or a computer facility of another type that may be used to solve the task shall not be considered as a computer failure. If this switching requir
16、es a complete or partial repetition of the task or testing (which caused the malfunction of the basic facility), it shall be considered as a computer failure. 2. Failures and malfunctions caused by imperfections of data carriers, effect of environmental factors not specified in the specifications, v
17、iolation by the attending personnel of the requirements specified in the operating documentation, as well as dependent failures and malfunctions, shall not be considered as computer failures and malfunctions. 3. An events (malfunctions) eliminated by hardware-software means automatically shall not b
18、e considered as computer malfunctions. 2.5. The values of mean time of restoring the operating state (Tr) shall be specified using the following series: 0.25; 0.50; 0.75; 1.00. _ * For computers (and their modifications) whose statement of work has been approved before the specified time, the values
19、 shall not be less than those specified in the statement of work or in the specifications for specific computers (modifications). p. 4 GOST 16325-88 2.6. The average service life of the computer (Tser.av) shall not be less than 10 years. The average service life of the computer shall be established
20、taking into consideration the reconditioning of its components whose average service life is less than 10 years. 2.7. The factor of technical use (Kt.u)* shall not be less than 0.95. The value of Kt.u shall be established taking into consideration the following: round-the-clock operation of the comp
21、uter during one year; the presence of spare parts, tools and accessories for autonomous maintenance service. 2.8. The average shelf life for the computer (before commissioning) (Tsh.av) shall not be less than nine months. 2.9. The readiness factor (Kr) and its values shall be established in addition
22、 to basic indicators in justified cases by agreement with the customer. 2.10. Programs for ensuring reliability shall be developed for the stages of development, manufacturing and operation in accordance with GOST 21552-84. 3. REQUIREMENTS FOR RESISTANCE TO ENVIRONMENTAL FACTORS 3.1. Depending on st
23、ability to the effects of environmental climatic factors during operation, computers shall comply with group 1 or 2 in accordance with GOST 21552-84. Normal climatic operating conditions for computers shall comply with GOST 21552-84. 3.2. The value of temperature inside the computer devices and buil
24、t-in devices shall comply with GOST 21552-84. Where technically justified, other values of excess air temperature inside the devices may be specified in the statement of work and/or the specifications taking into consideration permissible conditions for the used accessories and materials. 3.3.
