IEC 60704-2-14:2013 specifies the measuring conditions to provide for sufficient accuracy in determining the noise emitted and comparing the results of measurements taken by different laboratories, whilst simulating as far as possible the practical use of household refrigerators, frozen-food storage cabinets and food freezers. It is recommended to consider the determination of noise levels as…

IEC 61326-1:2012 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 61326-1:2012 specifies requirements for immunity and emissions regarding electro-magnetic compatibility (EMC) for…

IEC 61326-1:2012 specifies requirements for immunity and emissions regarding electromagnetic compatibility (EMC) for electrical equipment, operating from a supply or battery of less than 1 000 V a.c. or 1 500 V d.c. or from the circuit being measured. Equipment intended for professional, industrial-process, industrial-manufacturing and educational use is covered by this part. This second edition…

IEC/TR 61000-1-6:2012(E), which is a technical report, provides methods and background information for the assessment of measurement uncertainty. It gives guidance to cover general measurement uncertainty considerations within the IEC 61000 series. The objectives of this Technical Report are to give advice to technical committees, product committees and conformity assessment bodies on the…

ISO 5264-2:2011 specifies a method for the laboratory beating of pulp using a PFI mill. The description is limited to the sampling, preparation and beating of the pulp and the beating equipment. In principle, this method is applicable to all kinds of chemical and semi-chemical pulps. In practice, the method might not give satisfactory results with certain pulps having extremely long fibres.

ISO 9239-1:2010 specifies a method for assessing the wind-opposed burning behaviour and spread of flame of horizontally mounted floorings exposed to a heat flux radiant gradient in a test chamber, when ignited with pilot flames. This method is applicable to all types of flooring. e.g. textile carpet, cork, wood, rubber and plastics coverings as well as coatings. Results obtained by this method…

ISO/TR 19972-1:2009 provides a means for determining the reliability of hydraulic fluid power components using: estimates from a design analysis; analysis of laboratory testing to failure or suspension; analysis of field data; analysis of a substantiation test. These methods apply to the first failures without repairs, but exclude certain infant mortality failures. Specific component test…
