Packaging — Dimensional tolerances for general purpose sacks — Part 1: Paper sacks
The tolerances of the following dimensions of paper sacks as defined in ISO 6590-1 are specified: ply grammage, length of sack, width of sack, width of gusset, circumference of sack with gussets, width of bottom, width of valve, position of the leading edge of the valve sleeve, print position on sack.
Information technology — Portable Operating System Interface (POSIX) — Part 2: Shell and Utilities
This part of ISO/IEC 9945 defines a standard source-code-level interface to command interpretation, or "shell," services and common utility programs for applica- tion programs. These services and programs are complementary to those specified by ISO/IEC 9945-1: 1990 (IEEE Std 1003.1-1990) {8}, hereinafter referred to as "POSIX.1 {8}." When the User Portability Utilities Option…
Information technology - Coded representation of picture and audio information - Progressive bi-leve...
Defines a bit-preserving (lossless) compression method for coding image bit-planes and is particularly suitable for bi-level (two-tone, including black-white) images. Specifies requirements and test methods and gives datastream examples.
Information technology - Telecommunications and information exchange between systems - High-level da...
Defines a single-exchange negotiation procedure for establishing operational characteristics when either one or more HDLC stations are capable of providing multiple selections. Provides a means for interchanging the necessary information to establish, at a minimum, a data link connection between two correspondents wishing to communicate. Describes the general purpose XID frame information field…
Information technology - Telecommunications and information exchange between systems - High-level da...
Specifies the frame structure for data communication systems using bit-oriented high-level data link control (HDLC) procedures. Defines the relative positions of the various components of the basic frame and the bit combination for the frame delimiting sequence (flag). The mechanisms used to achieve bit pattern independence (transparency) within the frame are also defined. In addition, two frame…

Describes the HDLC unbalanced classes of procedures, the HDLC balanced class of procedures, and the HDLC connectionless classes of procedures for synchronous or start/stop data transmission. The procedures use the HDLC frame structure defined in ISO/IEC 3309 and the HDLC elements of procedures described in ISO/IEC 4335.
Information technology -- Telecommunications and information exchange between systems - High-level d...
Specifies elements of data link control procedures for synchronous or start/stop, code-transparent data transmission using the HDLC frame structure specified in ISO/IEC 3309 and independent frame numbering in both directions. These HDLC elements of procedures are defined specifically in terms of the actions that occur on receipt of commands at a secondary station or a combined station.

Performance standards in building — Performance test for precast concrete floors — Behaviour under n...
Defines test procedures for determining the mechanical performance of precast concrete floors made of a single piece, or made up of precast joists (reinforced concrete or precast concrete) completed with filler blocks and concrete poured in situ. The parameters measured are: the maximum load, which does not result in collapse, the instantaneous and deferred deformations under imposed load, and…

The test procedures defined are: transverse dynamic bond test on finished floors, penetration resistance test of the finished floor, and indentation/bending test on filler blocks (this test is designed to verify safety at the assembly stage). Applies to all kinds of precast concrete floors and to components thereof.
