Rubber — Determination of adhesion to rigid materials using conical shaped parts
This document specifies a method for the determination of the static vulcanized adhesion strength of rubber compounds to rigid materials. The test piece is composed of two conical ends of the rigid material, joined by a cylinder of rubber.
The adhesion is obtained by a bonding system which can include not only the rigid material and the rubber compound, but other elements such as thin alloy…
Rubber, vulcanized — Determination of adhesion to wire cord
This document specifies two methods for determining the adhesion strength of vulcanized rubber to wire cord which is embedded in the rubber.
The two methods do not necessarily give the same results.
They are applicable primarily to test pieces prepared in the laboratory under standard conditions and used for the development and control of materials and processes utilized in the manufacture of…
Water quality — Detection and quantification of Legionella spp. and/or Legionella pneumophila by con...
This document provides the guidelines, minimum requirements and performance characteristics intended to guarantee that manufactured systems intended for on-site/field use (i.e. outside the laboratory) provide reliable and reproducible results.
This document specifies the requirements for technologies that enable on-site detection and quantification of Legionella spp. and L. pneumophila using a…
Water quality — Sampling — Part 3: Preservation and handling of water samples
This document specifies the general requirements for sampling, preservation, handling, transport and storage of all water samples for physicochemical, chemical, hydrobiological and microbiological analyses and determination of radiochemical analytes and activities.
Guidance on the validation of storage times of water samples is provided in ISO/TS 5667-25.
This document is not applicable to water…
Electronic displays - Part 2-7 : Measurements of optical characteristics - Tiled displays
IEC 62977-2-7:2024 specifies standard measuring conditions and measurement methods for determining the optical characteristics of tiled displays which consist of multiple display modules in order to form one screen. These methods apply to emissive and transmissive direct view flat displays that render real 2D images with all modules lying in the same plane. The methods are applicable in…
Indoor air — Part 9: Determination of the emission of volatile organic compounds from samples of bui...
This document specifies a general laboratory test method for the determination of the area specific emission rate of volatile organic compounds (VOCs) from samples of newly produced building products or furnishing under defined climate conditions. The method can also, in principle, be applied to samples of aged products. The emission data obtained can be used to calculate concentrations in a…
Crude petroleum, petroleum products and related products — Determination of density — Laboratory den...
This document specifies a method for the determination, using an oscillating U-tube density meter, of the density of crude petroleum and related products within the range 600 kg/m3 to 1 100 kg/m3, which can be handled as single-phase liquids at the test temperature and pressure.
This document is applicable to liquids of any vapour pressure as long as suitable precautions are taken to ensure that…
