Natural rubber latex concentrate — Determination of total phosphate content by spectrophotometric me...
This document specifies a method for the determination of total phosphate content of natural rubber latex concentrate. This method is not necessarily suitable for latex from natural sources other than the Hevea brasiliensis.
Rubber latex — Styrene-butadiene — Determination of bound styrene content
This document specifies a method for the determination of the bound styrene content of styrene-butadiene rubber (SBR) lattices.
The method is applicable to hot (approximately 50 °C) emulsion polymerized SBR lattices having a bound styrene content, expressed on the SBR content, of up to 55 % and to cold (approximately 5 °C) emulsion polymerized SBR lattices having a bound styrene content between…
Dynamic metadata high dynamic range impacts on TV power consumption
IEC TR 63449:2023 presents a study of the impact of high dynamic range (HDR) technologies with "dynamic metadata" on TV luminance and power consumption. It compares the power consumption of content with dynamic metadata to the same content without dynamic metadata. Non-dynamic "static metadata" HDR technologies such as HDR10 and non-metadata HDR such as HLG, were previously…
Essential oils — General requirements for labelling and marking of containers
This document specifies the general requirements for the labelling and marking of containers for essential oils to enable the identification of the contents.
This document specifies the requirements and test methods for sterilized absorbent points used in endodontic procedures. Absorbent points are marketed sterilized or non-sterilized. The requirements apply to absorbent points which have been sterilized once in a manner approved by the manufacturer. This document specifies numerical systems and a colour-coding system for designating the sizes of…

Welding consumables — Solid wire electrodes, solid strip electrodes, solid wires and solid rods for ...
This document specifies requirements for classification of solid wire electrodes, solid strip electrodes, solid wires and solid rods for fusion welding of nickel and nickel alloys. The classification of the solid wire electrodes, solid strip electrodes, solid wires and solid rods is based on their chemical composition. It includes those compositions in which the nickel content exceeds that of any…
This document specifies four methods for the quantitative determination of the material extractable from raw rubbers, both natural and synthetic; two of the methods are also applicable to the unvulcanized and vulcanized rubber compounds.
Method A measures the mass of the solvent extract, after evaporation of the solvent, relative to the mass of the original test portion.
Method B measures the…
Textiles — Determination of components in flax fibres
This document specifies the test methods for the quantitative analysis of cellulose, hemicellulose, lignin, pectin, fat and wax content in flax fibres.
This document is applicable to flax fibres and can be used as a reference for testing other bast fibres.
