Pressure vessel steels not included in ISO 2604, Parts 1 to 6 — Derivation of long-time stress ruptu...
Defines a procedure for obtaining and for assessing the data necessary to establish long-time stress rupture values for steels for pressure purposes for steels where properties different from those internationally agreed are being claimed. The purpose of a standard procedure is to minimize any differences in long-time estimates obtained in different countries due to differences in the quantity…
Data Communication - 15-pin DTE/DCE Interface Connector and Pin Assignments
1 Scope and field of application
This International Standard specifies the 15-pin connector and the assignment
of connector pin numbers at the interface between data terminal equipment (DTE)
and data circuit terminating equipment (DCE) where CCITT¹) Recommendations
X.24, X.26, and X.27 are applicable.
Supplement No.1 to CSA Standard CAN3-Z349.1-79, Dental Terminology and
Definitions
Defines, in both English and French, terminology pertaining to
dental science, dental materials, dental equipment and the

Polyethylene Sheet for Use in Building Construction
1.1
This standard applies to flexible sheet material made from low-density
polyethylene, primarily intended for use in building construction to retard the
passage of moisture and water vapor. The purpose of this standard is to
control the thickness of polyethylene sheet material and to provide a basis for
its procurement.
1.2
Material to this standard may also be suitable for use as a vapor…
Personal eye-protectors — Filters and eye-protectors against laser radiation
Specifies requirements for spectacle filters and protectors within the spectral region 0,2 to 1000 micron. The work, which was staggered over several years, represents a basic study for which a majority consensus was reached at the international level. To take account of new developments and knowledge relating to lasers a revision of this standard will be undertaken.
The Standard specifies the following characteristics of the oil. Appearance: Clear, mobile liquid. Colour: Pale yellow to pale brownish yellow. Odour: Characteristic of oil of Ceylon citronella. Relative density at 20/20 °C: 0,894 - 0,910. Refractive index at 20 °C: 1,4790 - 1,4870. Optical rotation at 20 °C: Range from - 22 to - 12 . Miscibility with 80 % (V/V) ethanol at 20 °C: 1 : 2.
