Fibre optic connector interfaces - Part 16: Type PN connector family
Defines the standard interface dimensions for type PN family of connectors which is a duplex plug connector characterized by a 10,16 mm pitch, and a 2,5 mm nominal ferrule diameter.
Ships and marine technology — Clear openings for external single-leaf doors
This International Standard lays down standardized dimensions of clear openings for all types of external singleleaf
doors, on board ships, for which coamings are required.
These dimensions shall be used as nominal sizes for these doors of ships.
Information technology - Data interchange on 120 mm optical disk cartridges using +RW format - Capac...
This International Standard specifies the mechanical, physical and optical characteristics of 120 mm
rewritable optical disks with capacities of 3,0 Gbytes and 6,0 Gbytes. It specifies the quality of the recorded and
unrecorded signals, the format of the data and the recording method, thereby allowing for information interchange
by means of such disks. The data can be written, read and…

Petroleum products and crude petroleum — Determination of vapour pressure — Reid method
This International Standard specifies a method for the determination of the vapour pressure of liquid petroleum
products consisting of essentially or wholly of hydrocarbon components, or containing oxygenated hydrocarbons of
specific types and at specified maximum concentrations. The method does not apply outside these concentration
levels, nor to any blends containing methanol or other…
Non-Recirculating Direct Gas-Fired Industrial Air Heaters
1.1 Scope
1.1.1 This standard applies to newly produced, direct gas-fired industrial air heaters of the non-recirculating type, hereinafter referred to as heaters, whose purpose is to offset building heat loss. All air to the heater shall be ducted directly from outdoors and the products of combustion generated by the heater are released into the air stream being heated.
Heaters covered by…
Fibre-reinforced plastic composites — Determination of compressive properties in the in-plane direct...
1.1 This International Standard specifies two methods for determining compressive properties, in directions parallel
to the plane of lamination, of fibre-reinforced plastic composites.
1.2 The compressive properties are of interest for specifications and quality-control purposes.
1.3 Two loading methods and two types of specimen are described. They are:
Method 1: provides shear loading of the…
