ISO 6134:2017 specifies requirements for two types of hoses and hose assemblies, low pressure with a maximum working pressure of 6 bar and high pressure with a maximum working pressure of 18 bar, made of rubber and hose fittings made of metal, designed to convey saturated steam and hot water condensate. Each type is divided into two classes having either an oil resistant or non-oil resistant cover. NOTE Information on the frequency of testing of hose assemblies in use and storage is given in Annex A and Annex B.

 

This document specifies requirements for two types of hoses and hose assemblies, low pressure with a maximum working pressure of 0,6 Mpa (6bar) and high pressure with a maximum working pressure of 1,8 Mpa (18bar) made of rubber and hose fittings made of metal, designed to convey saturated steam and hot water condensate. Each type is divided into two classes having either an oil resistant or non-oil resistant cover.

 

This document describes a practical procedure for nucleotide sequence database evaluation and validation. This document describes minimum requirements for the validation of a nucleotide sequence database. This document is applicable only for databases consisting of entries of nucleotide sequences. This document is not applicable to the general evaluation of the entire database quality including the quality of each data entry.

 

This document specifies a framework for data interoperability of data systems, such as databases, data management systems, web interfaces, API, etc. that manage stem cell data. It is applicable to all human stem cell types. This document does not apply to other animal stem cells nor plant stem cells. This document specifies considerations and requirements of stem cell data for data interoperability, such as cell characteristics, applied technologies, ethical requirements, and data sharing, analysis, and accessibility. This document describes an interoperable framework for stem cell data, which can be used for existing systems or existing architectures. The intended audiences for this document are data generators, implementors of IT infrastructure to handle the data, data providers and data consumers.

 

This document specifies requirements for the biobanking of human neural stem cells (hPSC-NSCs) derived from human pluripotent stem cells (hPSCs), including the requirements for the differentiaton, culture, characterization, quality control, storage, thawing and transport of hPSC-NSCs. 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 hPSC-NSCs used for research and development in the life sciences. This document does not apply to hPSC-NSCs for the purpose of in vivo application in humans, clinical applications or therapeutic use.

 

This document specifies a basic laboratory test method for deinkability of woodfree printed paper products as a mixture under alkaline conditions by means of single stage flotation deinking and fatty acid-based collector chemistry. The woodfree printed paper product of interest is tested as a mixture containing 10 % by weight of the woodfree printed paper with the balance comprising a mixture of mechanical pulp based printed paper products.

 

ISO 4892-3:2016 specifies methods for exposing specimens to fluorescent UV radiation, heat and water in apparatus designed to simulate the weathering effects that occur when materials are exposed in actual end-use environments to global solar radiation, or to solar radiation through window glass. The specimens are exposed to fluorescent UV lamps under controlled environmental conditions (temperature, humidity and/or water). Different types of fluorescent UV lamp can be used to meet all the requirements for testing different materials. Specimen preparation and evaluation of the results are covered in other International Standards for specific materials. General guidance is given in ISO 4892-1. NOTE Fluorescent UV lamp exposures for paints, varnishes and other coatings are described in ISO 11507.

 

This Standard specifies safety requirements for free standing children's high chairs that elevate children to dining table height usually for the purposes of feeding or eating. Children's high chairs are for children up to 3 years of age who are capable of sitting unaided. With the exception of special high chairs for medical purposes, this standard applies to children's high chairs for domestic and non-domestic use.

 

This document specifies a laboratory method for the determination of chlorophyll a content in algae. The method was initially tested and evaluated on the microalgae species Nannochloropsis and a heat treated algal product tomato soup with Nannochloropsis supplement, and the macro algae species Ulva sp, Furcellaria lumbricalis, and Saccharina latissima. During an Interlaboratory Trial the method was tested on the microalgae species Nannochloropsis and the macro algae species Saccharina latissima. The microalgae species Nannochloropsis and Phaodactlylum and the macro algae species Ulva sp and Saccharina latissima were tested in a Round Robin test. This document is only validated for chlorophyll a, but it can be used for other chlorophylls as well. If possible, an attempt will be made to incorporate an alternative method than the HPLC method proposed into the standard (informative or normative), on the condition that research on the use of a cheaper method fits into the budget allocated for this topic. The more, it is imperative that this additional method should obtain comparable results and accuracy as the HPLC method. The schedules of all the additional experiments mentioned are based on the schedule of the standard on chlorophyll.

 

This document specifies the requirements for the design, manufacture and testing of cylinders, tubes and other pressure vessels of steel, stainless steel, aluminium alloys or of non-metallic construction material. These are intended for the stationary storage of gaseous hydrogen of up to a maximum water capacity of 10 000 l and a maximum allowable working pressure not exceeding 1 100 bar, of seamless metallic construction (Type 1) or of composite construction (Types 2, 3 and 4), hereafter referred to as pressure vessels. NOTE Additional requirements with regard to assemblies (manifolded cylinders and tubes and other pressure vessels) are not covered by this document. This document is not applicable to Type 2 and 3 vessels with welded liners. This document is not applicable to pressure vessels used for solid, liquid hydrogen or hybrid cryogenic-high pressure hydrogen storage applications. This document is not applicable to external piping which can be designed according to recognized standards.

This document provides requirements and guidelines for comparing the life cycles of bio-based products with their fossil-based equivalents. NOTE The term “equivalents” generally refers to the “functional equivalence”. This document builds on existing LCA methodology and provides requirements and guidance on specific topics relevant for making well-balanced comparisons.
