Safety of laser products - Part 2: Safety of optical fibre communication systems (OFCS)
Provides requirements and specific guidance for the safe operation and maintenance of optical fibre communication systems (OFCS). In these systems optical power may be accessible outside the confinements of transmitting equipment or at great distance from the optical source. This Part 2 requires the assessment of hazard levels at accessible locations as a replacement for classification according…

Specification for radio disturbance and immunity measuring apparatus and methods - Part 1-3: Radio d...
This part of CISPR 16 is designated a basic standard, which specifies the characteristics and calibration of the absorbing clamp for the measurement of radio disturbance power in the frequency range 30 MHz to 1 GHz. This second edition cancels and replaces the first edition published in 2003. It constitutes a technical revision. In this edition a more detailed calibration method for the absorbing…
Fixed capacitors for use in electronic equipment - Part 22-1: Blank detail specification: Fixed surf...
is a supplementary document to the sectional specification and contains requirements for style, layout and minimum content of detail specifications. Detail specifications not complying with these requirements may not be considered as being in accordance with IEC specifications nor shall they so be described. The contents of the corrigendum of September 2004 have been included in this copy.
Fixed capacitors for use in electronic equipment - Part 22: Sectional specification: Fixed surface m...
applies to fixed unencapsulated surface mount multilayer capacitors of ceramic dielectric, Class 2, for use in electronic equipment. These capacitors have metallized connecting pads or soldering strips and are intended to be mounted on printed boards, or directly onto substrates for hybrid circuits.

ISO 302:2004 specifies a method for the determination of the Kappa number of pulp. The Kappa number is an indication of the lignin content or bleachability of pulp.
ISO 302:2004 is applicable to all kinds of chemical pulps and semi-chemical pulps within the Kappa number range 1 to 100. For pulps with a Kappa number exceeding 100, use the chlorine-consumption procedure (ISO 3260) to describe the…
