This document is applicable to pure cultures of STEC. The present standard describes the characterization of STEC strains, isolated from any source. In particular, the characterization of STEC strains described here regard: - subtyping of the Stx-coding genes; - determination of the presence of eae gene; - determination of the presence of aggR gene; - identification of the presence of genes…

This standard specifies the characterization of ceramic slurry for use as feedstock in vat photopolymerization additive manufacturing (AM) process. The characterization includes the composition and properties of the slurry, such as solids content, dynamic viscosity, particle size distribution, chemical composition, and solid dispersion stability. This standard also provides available methods…

Scope of the proposed deliverable. This international standard (part 1 or part 2) specifies the method for measuring tread abrasion mass loss of a candidate tyre per unit distance travelled, under loaded conditions, by using vehicles on road (part 1) or an external drum tester (part 2). Each test method specified in Part 1 and Part 2 measures abrasion performance of a candidate tyre on the…

Preparation of a new ISO standard using a recently published CEN standard as a basis. The WG will examine this in detail and make any technical changes as required to ensure conformance with specific ISO requirements It is expected that the ISO standard will closely follow the requirements of the published CEN standard whilst complying with the ISO template

This Standard specifies the standard test method useful to assess the performance of dust collection systems utilizing integrated fans (compact type dust collector), which shall be applied with or without flow control. This standard is not intended to offer the superiority or inferiority of performance between dust collectors, but specifies a standard test method that provides users with…

ISO 8913:2006 specifies requirements for lightweight polytetrafluoroethylene (PTFE) hose assemblies for use in aircraft hydraulic systems at temperatures between - 55 °C and 204 °C (- 65 °F and 400 °F), and at a nominal pressure up to 3 000 psi (20 684 kPa) or 21 000 kPa (3 046 psi). The hose assemblies are also suitable for use within the same temperature and pressure limitations in aircraft…

This document defines testing coupons and methods for the evaluation of the compression strength of AM lattice designs. The standardized test coupons will accommodate the application of a variety of lattice designs, while standardizing the evaluation method. This document is generally intended to be used in validation or verification activities for an additively manufactured component that…

This part of standard wants to provide a testing and calculating methods for annual performance factor of sensible recovery ventilator ruled by the ISO 16494,It is the third part of ISO/NP5222.

ISO 14739-1:2014 describes PRC 10001 of a product representation compact (PRC) file format for three dimensional (3D) content data. This format is designed to be included in PDF (ISO 32000) and other similar document formats for the purpose of 3D visualization and exchange. It can be used for creating, viewing, and distributing 3D data in document exchange workflows. It is optimized to store,…

ISO 14116:2015 specifies the performance requirements for the limited flame spread properties of all materials, all material assemblies, and protective clothing in order to reduce the possibility of the clothing burning when in occasional and brief contact with small flames and thereby constituting a hazard. Additional requirements for clothing are also specified, including design requirements,…
