Lead-acid starter batteries - Part 4: Dimensions of batteries for heavy vehicles
This part of IEC 60095 is applicable to lead-acid batteries used for starting, lighting and ignition of heavy trucks, commercial vehicles, busses and agricultural trucks. This second edition cancels and replaces the first edition published in 1989 and its Amendment 1 (1996). It constitutes a technical revision. The main technical changes in this new edition relate to the reduction of the number…
Piezoelectric and dielectric devices for frequency control and selection - Glossary - Part 4-3: Mate...
Specifies the terms and definitions for materials applied for devices using waveguide type dielectric resonators representing the state-of-the-art, which are intended for use in the standards and documents of IEC technical committee 49.
Electromagnetic compatibility (EMC) - Part 3-13: Limits - Assessment of emission limits for the conn...
This part of IEC 61000 provides guidance on principles which can be used as the basis for determining the requirements for the connection of unbalanced installations (i.e. three-phase installations causing voltage unbalance) to MV, HV and EHV public power systems (LV installations are covered in other IEC documents). For the purposes of this report, an unbalanced installation means a three-phase…
Identification cards - Recording technique - Part 8: Magnetic stripe - Coercivity of 51,7 kA/m (650 ...
ISO/IEC 7811-8:2008 is one of a series of International Standards defining the characteristics of identification cards. It provides criteria to which cards shall perform and specifies the requirements for such cards used for international interchange. It takes into consideration both human and machine aspects and states minimum requirements.
ISO/IEC 7811-8:2008 specifies requirements for a 51,7…
Rubber and plastics hoses for marine-engine wet-exhaust systems — Specification — Technical Corrigen...
ISO 13363:2004 specifies requirements for three types and two classes of hose. The hoses are intended for use in marine-engine wet-exhaust systems (where the exhaust gases are mixed with the discharge of cooling water). The standard does not apply to outboard-motor/personal water craft.
The three types are:
type 1: a softwall hose, made of oil-resistant material, with a synthetic-fabric…
Energy performance of buildings — Calculation of energy use for space heating and cooling
ISO 13790:2008 gives calculation methods for assessment of the annual energy use for space heating and cooling of a residential or a non-residential building, or a part of it, referred to as “the building”.
This method includes the calculation of:
the heat transfer by transmission and ventilation of the building zone when heated or cooled to constant internal temperature…
