Intelligent transport systems — Communications access for land mobiles (CALM) — 2G Cellular systems
ISO 21212:2008 determines the air interface for second generation (2G) cellular networks and 2G systems (e.g. using WAP and I-Mode type protocols) to be compliant to CALM, i.e., requirements that must be met before a 2G system can be incorporated into a CALM system. In particular, it specifies protocols and parameters that 2G systems shall include to support prolonged, long-range, high data rate…
Rubber and plastics hoses and tubing — Textile-reinforced types — Sub-ambient temperature crush test
ISO 28702:2008 specifies a test method for measuring the low-temperature brittleness of rubber and plastics hoses with a textile reinforcement and tubing at sub-ambient temperatures by crushing a test piece of the hose.
This International Standard is only applicable to hoses with a nominal bore up to and including 100 mm.
IEC 62059-31-1:2008 provides one of several possible methods for estimating product life characteristics by accelerated reliability testing. In this standard, elevated, constant temperature and humidity is applied to achieve acceleration. The method takes into account the effect of voltage and current variation. It is applicable to all types of metering equipment for energy measurement, tariff…
EMC IC modelling - Part 2: Models of integrated circuits for EMI behavioural simulation - Conducted ...
IEC 62433-2:2008 specifies macro-models for ICs to simulate conducted electromagnetic emissions on a printed circuit board. The model is commonly called Integrated Circuit Emission Model - Conducted Emission (ICEM-CE). The ICEM-CE model can also be used for modelling an IC-die, a functional block and an Intellectual Property block (IP). The ICEM-CE model can be used to model both digital and…
