Rigid Protective Covers for Live Working on a.c. Installations
1 SCOPe
International Standard IEC 1229 is applicable to rigid insulating covers for
live working on a.c. installations, including those described in IEC 743.
The barriers, having dielectric withstand which depends on the positioning
clearance, are excluded from this standard.
1.1 Classes
Six classes of covers, differing in electrical characteristics, are provided
and designated as…
Photography — Paper dimensions — Rolls for printers
This International Standard specifies the aim and tolerance values for the nominal widths of rolls of black-and-white
and colour photographic papers for use in contact and projection printers.
It also specifies splice parameters, core dimensions, requirements for winding, and package marking.
Indoor, ambient and workplace air — Sampling and analysis of volatile organic compounds by sorbent t...
This part of ISO 16017 gives general guidance for the sampling and analysis of volatile organic compounds (VOCs)
in air. It is applicable to ambient, indoor and workplace atmospheres and the assessment of emissions from
materials in small- or full-scale test chambers.
This part of ISO 16017 is appropriate for a wide range of VOCs, including hydrocarbons, halogenated hydrocarbons,
esters, glycol…
Fluid power systems and components — 16 mm square electrical connector with earth contact — Characte...
This International Standard specifies the following characteristics and requirements for a general-purpose,
electrical-plug connector with two or three contacts plus earth, for use with solenoids:
_ the electrical characteristics of the connector;
_ the dimensions of the contacts;
_ the means of fixing the plug to the socket;
_ the sealing procedure between the plug and the socket;
_ usage…
Information technology — Data communications — X.25 Packet Layer Protocol for Data Terminal Equipmen...
This International Standard specifies the procedures, formats and
facilities at the Packet Layer for Data Terminal Equipment (DTE)
operating in conformance with ITU-T Recommendation X.25.
Both Virtual Call and Permanent Virtual Circuit modes of
operation are covered.
The Packet Layer protocol specified herein can be used in both
Open Systems Interconnection (OSI) and non-OSI environments.
When…
Petroleum products — Estimation of net specific energy of aviation turbine fuels using hydrogen cont...
This International Standard describes a procedure for the estimation of the net specific energy of aviation turbine
fuels using hydrogen content data. It is not applicable to pure hydrocarbons.
The method is purely empirical and is applicable only to liquid hydrocarbon fuels derived by normal refining
processes from conventional crude oil which conform to the requirements of specifications for…
Refractory products — Determination of resistance to carbon monoxide
This International Standard specifies a method for determining the comparative resistance of refractory materials to
carbon monoxide disintegration.
The test is intended to be more severe than conditions encountered in service in order to enable probable behaviour
of refractory materials to be assessed in a relatively short time.
Petroleum products — Determination of water — Coulometric Karl Fischer titration method
This International Standard specifies a method for the direct determination of water in petroleum products boiling
below 390 °C. It covers the mass fraction range 0,003 % (m/m) to 0,100%(m/m). It is not applicable to products
containing ketones or to residual fuel oils.
This International Standard may be applicable to lubricating base oils. However, the precision has not been
established for…
Industrial automation systems — Numerical control of machines — NC processor output — Post processor...
This International Standard defines the elements of a set of
post processor statements to be used in numerical control
software. These statements are encoded on 2 000 class
and 20 000 class CLDATA records or their equivalent.
Each processor using one of the ISO numerical control
programming languages shall be capable of producing post
processor command type CLDATA records as defined in
this…
