Clinical laboratory testing and in vitro diagnostic test systems — Broth micro-dilution reference me...
This document describes a method for testing the susceptibility to antifungal agents of yeasts, including Candida spp. and Cryptococcus neoformans, that cause infections. The reference method described here has not been used in studies of the yeast forms of dimorphic fungi, such as Blastomyces dermatitidis and/or Histoplasma capsulatum variety capsulatum. Moreover, testing filamentous fungi (…
Software engineering - Trial use standard for software non-functional sizing measurements
This document defines a method for the sizing of non-functional software requirements. It complements ISO/ IEC 20926:2009, which defines a method for the sizing of functional user requirements (FUR).1
This document also describes the complementarity of functional and non-functional sizes, so that sizing both functional and non-functional requirements (NFR) do not overlap. It also describes how…
