This document specifies requirements for the biobanking of human natural killer (NK) cells derived from human pluripotent stem cells (hPSCs), including the requirements for the differentiaton, culture, characterization, quality control, storage, thawing and transport of NK cells. Requirements for the collection of biological source material, the transport to and reception of biological source material and hPSCs at the biobank, as well as the establishment, expansion and QC of hPSCs are covered in ISO 24603. This document is applicable to all organizations performing biobanking of human NK cells used for research and development in the life sciences. This document does not apply to human NK cells for the purpose of in vivo application in humans, clinical applications or therapeutic use.

 

This document specifies a gradient column method for the determination of the density of non-cellular moulded or extruded plastics or pellets in void-free form. Density gradient columns are columns containing a mixture of two liquids, the density in the column increasing uniformly from top to bottom.

 

This document establishes a model-free approach for the isoconversional kinetic analysis of chemical reactions and phase transitions. The isoconversional principle is based on the assumption that the reaction rate at a given conversion depends solely on the temperature, i.e., is independent on the scan rate. This document establishes a method for the determination of the activation energy as a function of the conversion of the reaction or transition. The method is applicable to dynamic and isothermal temperature program measurements done by Differential Scanning Calorimetry (DSC) or Thermogravimetry (TG). It can be applicable to other measurement techniques, too, that enable the determination of conversion curves. The method is applicable to the prediction of the kinetic behaviour of reactions and transitions even in temperature regions that are not experimentally accessible. The method is not applicable in the glassy state of polymers.

 

This document specifies a method for the determination of the penetration temperature of thermoplastics using thermomechanical analysis (TMA).

 

This document specifies a gradient column method for the determination of the density of non-cellular moulded or extruded plastics or pellets in void-free form. Density gradient columns are columns containing a mixture of two liquids, the density in the column increasing uniformly from top to bottom. NOTE Density is frequently used to follow variations in physical structure or composition of plastic materials. Density can also be useful in assessing the uniformity of samples or specimens. The density of plastic materials can depend upon the choice of specimen preparation method. When this is the case, precise details of the specimen preparation method are intended to be included in the appropriate material specification.

 

ISO 29601:2011 specifies procedures for detecting the presence of porosity in a protective paint system of any thickness on a steel or other metallic substrate. The procedures given are based on methods using two different types of test equipment, the choice of equipment depending on the dry film thickness. These procedures are only applicable to the testing of electrically non-conductive parts of a paint system. The test methods specified are mainly intended for use with new coatings, but can also be used for coatings which have been in service for some time. In the latter case, it is important to bear in mind that the coating might have been penetrated by substances in contact with the coating during service.

This European Standard specifies the classifications, requirements and test methods for non-covered unplasticized poly(vinyl chloride) (PVC-U) profiles intended to be used for the fabrication of windows and doors. NOTE 1 For editorial reasons in this document the term "window" is used for window/door.

 

 

 

This document specifies an instrumental method for determining the yellowness index and change in yellowness index on clear, translucent, or opaque plastics.

 

This document specifies methods of measurement for the determination of the dimensions of all types of mattresses, bed frames, divans and bed bases intended for adult size. It also includes recommended tolerances based on any nominal dimension, in order to ensure the correct fit between the bed components. It does not apply to air beds/mattresses and water beds/mattresses, nor to mattress pads that are placed on top of the main support mattress. It does not apply to the dimensions of bed bases for bunk beds and high beds.
