Paper and board — Sampling to determine average quality
This Iinternational Standard specifies a method of obtaining a representative sample from a lot of paper or board, including solid and corrugated fibreboard (see ISO 4046:1978), for testing to determine whether or not its average quality complies with set specifications.
It defines the conditions which apply when sampling is carried out to resolve disputes between buyer and seller relating to a…
Radiotherapy equipment - Coordinates, movements and scales
Applies to equipment and data related to the process of teleradiotherapy, including patient image data used in relation with radiotherapy treatment planning systems, radiotherapy simulators, isocentric gamma beam therapy equipment, isocentric medical electron accelerators, and non-isocentric equipment when relevant. The object of this standard is to define a consistent set of coordinate systems…
Lubricants, industrial oils and related products (class L) — Family H (Hydraulic systems) — Specific...
This International Standard specifies the requirements for environmentally acceptable hydraulic fluids and is intended for hydraulic systems, particularly hydraulic fluid power systems. The purpose of this International Standard is to provide guidance for suppliers and users of environmentally acceptable hydraulic fluids, and for the direction of original equipment manufacturers of hydraulic…
Plastics — Determination of compressive properties
This International Standard specifies a method for determining the compressive properties of plastics under defined
conditions. A standard test specimen is defined but its length may be adjusted to prevent buckling under load from
affecting the results. A range of test speeds is included.
The method is used to investigate the compressive behaviour of the test specimens and for determining the…
Mechanical vibration — Balancing machines — Enclosures and other protective measures for the measuri...
This International Standard specifies requirements for enclosures and other protective measures used to minimize mechanical hazards produced by the rotor in the unbalance measuring station of centrifugal (rotational) balancing machines. The hazards are associated with the operation of balancing machines under a variety of rotor and balancing conditions. This International Standard defines…
Fibre optic active components and devices - Package and interface standards - Part 1: General and gu...
Aims to assure interchangeability in physical interfaces between fibre optic active components and devices supplied by different manufacturers. It defines physical interfaces only, and not performance standards.
Fibre optic connector interfaces - Part 4: Type SC connector family
Defines the standard interface dimensions for type SC family of connectors which is characterized by a 2,5 mm nominal ferrule diameter and includes a push-pull coupling mechanism which is spring loaded relative to the ferrule in the direction of the optical axis. This consolidated version consists of the first edition (1997), its amendment 1 (1999) and its amendment 2 (2001). Therefore, no need…
Basic specification for optical amplifier test methods - Part 5-3: Test methods for reflectance para...
Applies to commercial optical fibre amplifiers (OFAs) using active fibres. It establishes requirements for accurate measurements, by means of electrical spectrum analyser test method, of the maximum reflectance tolerable at input and output (as defined in clause 3 of IEC 61291-1). The accuracy for reflectance tolerable is +/-0,5dB.
Defines capability approval procedures for printed boards. In addition, a technology approval schedule may also be provided as an alternative for manufacturers employing a system of process control for establishing product conformity. Both CA and TA procedures apply to printed boards irrespective of their methods of manufacture, when they are ready for the mounting of components.
