Packaging — Flexible intermediate bulk containers (FIBCs) for non-dangerous goods
This document specifies materials, construction and design requirements, type test and marking requirements for flexible intermediate bulk containers (FIBCs) intended to contain non-dangerous solid materials in powder, granular or paste form, and designed to be lifted from above by integral or detachable devices.
This document also provides guidance on the selection and safe usage of FIBCs.
Nanotechnologies — Positron annihilation lifetime measurement for nanopore evaluation in materials
This document describes a method for performing positron annihilation lifetime measurements using a 22Na positron source that decays with β+ emission. The β+ (positron) lifetime is determined from a measurement of the lifetime of the ortho-positronium which ranges from 1 ns to 10 ns (ascribed to a pore size from approximately 0,3 nm to 1,3 nm in diameter), as observed for polymeric materials in…
Test methods for repair materials for water-leakage cracks in underground concrete structures — Part...
This document specifies a laboratory test method for evaluating the thermal stress resistance of water-leakage crack repair materials through permeability testing.
This document outlines general principles and procedures for the test method. This document does not specify specific variables that control the quantifiable parameters of the testing.
Clean cookstoves and clean cooking solutions — Guidance for evaluation
This document provides guidance for examining evaluation instruments that assess cooking systems. The goal is to ensure that a cooking system evaluation instrument achieves its objectives and is fit for a particular purpose. Doing so means recognizing that the stove is one part of a series of complex and interacting systems, many of which are variable.
The document includes procedures to ensure…
Fine bubble technology — Agricultural applications — Part 5: Practical data collection to promote th...
This document provides practical data collection of promoting the germination of typical vegetable seeds by applying ultrafine bubbles (UFBs) within the effective number concentrations for barley seeds specified in ISO 23016-2, ISO/TR 23016-3 and ISO 23016-4. While the application of UFB to barley seeds is systematically standardized, reports on UFB application to vegetable seeds germination are…
Test methods for repair materials for water-leakage cracks in underground concrete structures — Part...
This document specifies a laboratory test method for evaluating the substrate (crack) movement response of water-leakage crack repair materials through permeability testing.
This document outlines general principles and procedures for the test method. Specific variables that control the quantifiable parameters of the testing are filled in using relevant national standards or testing parameters,…
Test methods for repair materials for water-leakage cracks in underground concrete structures — Part...
This document specifies a laboratory test method for evaluating watertightness of water-leakage crack repair materials through permeability testing.
This document outlines general principles and procedures for the test method. This document does not specify specific variables that control the quantifiable parameters of the testing.
Information technology - JPEG XS low-latency lightweight image coding system - Part 3: Transport and...
This document defines transport and container formats for JPEG XS codestreams as specified in ISO/IEC 21122-1. It defines file formats for working with still image and motion image sequence files on computer platforms and gives guidance on how to embed the codestream in transport streams, allowing internet-based communication.
This document uses already existing specifications for file formats…
