Air quality. Assessment of uncertainty of a measurement method under field conditions using a second method as reference1 Scope This International Standard specifies a method for assessing the measurement uncertainty of a calibrated measurement method (test method) applied under field conditions using a second method as a reference (reference method). The reference method may not necessarily be a legally prescribed measurement method. The measurement uncertainty is derived from measurements made in parallel on real samples by comparing the measured values of the test

EN 17265 is a European standard on the determination of aluminium in foodstuffs to prevent adverse health effects on the central or peripheral nervous system

BS EN 50325-4 is the fourth part of the multiple series that specifies the following particular requirements for CANopen:

Professionals monitoring surveillance

NOTE 1 In general SPDs for PV applications do not contain a specific series impedance between the input/output terminals due to power efficiency considerations

BS EN ISO 9073-16 applies to any nonwoven fabrics which are intended for use as a barrier to the penetration of fluids

using a test specimen cut to form trouser-shaped legs

This European Standard specifies a method of assessing the behaviour of cable insulation subject to an electric arc initiated and maintained by contaminating fluid along the surface of the insulation

NOTE 2 The letter “H” expresses that these hoist chains are for hand operated hoists only

You will also find the following standards useful for the design and manufacture of equipment for play facilities:

complying with EN ISO 13686 and for which a detailed technical evaluation of the functional requirements is performed ensuring there are no other constituents or properties of the gases that can affect the integrity of the pipeline

These requirements supplement the general requirements in BS 7291‑1 which are also applicable

device authentication and conformance capabilities of electronic seals for communication to and from a seal and its associated reader
