Additive manufacturing of metals — Powder bed fusion — Material properties of stainless steel alloys
This document covers additively manufactured stainless steel components using full-melt powder bed fusion such as electron beam melting and laser melting. The components produced by these processes are used typically in applications that require mechanical properties similar to machined forgings and wrought products. Components manufactured to this specification are often, but not necessarily,…
Traditional Chinese medicine — Sophora tonkinensis root and rhizome
This document specifies the minimum requirements and test methods for Vietnamese Sophora root, which is the dried root and rhizome of Sophora tonkinensis Gagnep. (Fam. Leguminosae).
This document applies to Vietnamese Sophora root sold and used as Chinese materia medica (whole medicinal materials) and decoction pieces derived from this plant.
Water quality — Determination of pHT in sea water — Method using the indicator dye m-cresol purple
ISO 18191:2015 specifies a spectrophotometric determination of the pHt of sea water on the total hydrogen ion concentration pH scale using the indicator dye m-cresol purple. The total hydrogen ion concentration, [H+]t, is expressed as moles per kilogram of sea water. The method is suitable for assaying oceanic levels of pHt 7,4 to 8,2 for normal sea water of practical salinity ranging from 20 to…
Fasteners — Calculation methods for bolt/nut assemblies — Nut design
This document specifies design criteria for nuts specified in ISO 898-2 so that, under static tensile overload, the stripping fracture mode is prevented.
The design criteria are also applicable to non-standardized nuts or internally threaded elements with ISO metric screw threads (in accordance with ISO 68-1) mating with bolts. However, dimensional factors such as the width across flats or other…
Test methods for assessing the performance of gas-phase air cleaning media and devices for general v...
ISO 10121-2:2013 aims to provide an objective test method to estimate the performance of any full size gas filtration device (GPACD) for general filtration regardless of media or technique used in the device. In fact, the goal of this part of ISO 10121 is to avoid relating the test data to internal parameters altogether. The benefit with this approach is that customers of GPACDs will be able to…
Traditional Chinese medicine — Ganoderma lucidum fruiting body
This document specifies minimum requirements and test methods for Ganoderma lucidum fruiting body that is derived from Ganoderma lucidum (Leyss. ex Fr.) Karst.
It is applicable to Ganoderma lucidum fruiting body that is sold and used as Chinese materia medica (whole medicinal materials) and decoction pieces derived from this fungus.
Fixations — Goupilles cannelées — Cannelures centrales sur le tiers de la longueur
La présente Norme internationale prescrit les caractéristiques des goupilles cannelées en acier ou en acier inoxydable austénitique, à trois cannelures centrales constantes sur le tiers de leur longueur, non débouchantes et régulièrement espacées, de diamètre nominal, d1, de 1,5 mm à 25 mm inclus. Le matériau refoulé de chaque côté des cannelures forme un renflement dont le diamètre d2, supérieur…
