This document specifies a procedure for the determination of fluorine in copper and zinc sulfide concentrates by sodium hydroxide fusion and fluoride ion selective electrode (FISE) detection. Fluoride ions are leached from the sodium hydroxide fusion and presented to the FISE. Potential interfering ions are masked by the use of a complexing agent and control of solution pH. If the aluminium content in the concentrate is up to a mass fraction of 4,5 %, there is no effect of aluminium in this method. However, if the aluminium content in the concentrate exceeds a mass fraction of 4,5 %, there is a possibility that it can affect the analytical results. The method is applicable to fluorine in the following ranges: - copper concentrates: mass fraction of 0,008 % to 0,3 %; - zinc concentrates: mass fraction of 0,005 % to 0,1 %. The results of the trueness test can be found in Annex C.

This document surveys the range of existing sustainability frameworks available for critical mineral supply chains to aid understanding and assist in improving an organization’s sustainability outcomes. It includes an analysis of: — the requirements contained in existing sustainability guides or frameworks and where these tools are similar and where they diverge; — sustainability topic areas within existing guides and frameworks that have been accepted in different regions and jurisdictions. This document did not assess the effectiveness of existing standards or frameworks in improving the sustainability performance of their users or how performance was assessed. The results show that the existing sustainability frameworks are extensive and varied in the upstream supply chain. The analysis undertaken as part of this document will help inform the development of potential future ISO work programs and standards development, without duplicating or conflicting with existing frameworks. This document can also be used by organizations outside of ISO with respect to understanding available sustainability standards or frameworks.

SIGNIFICANCE AND USE
5.1 This guide is intended for use by developers of RMs and CRMs for the metals and mining industries.
5.2 The guidance is related to uniform procedures and requirements and is intended to prevent the proliferation of widely varying documentation practices, definitions, and terminology. Where the statements in this guide are made as imperatives, it is because the stated practices are fundamental to chemical metrology, not to CRM/RM development.
5.3 The material in this guide is intended to supplement and to clarify the contents of ISO Guide 31 and to provide guidance specific to the needs of the metals and mining industries.
5.4 The documents described in this guide are intended to contain the minimum amount of information required for a user to understand the material, to help a user judge the quality of the product, and to help a user employ it in appropriate ways. Neither this guide nor resultant documents are meant to be encyclopedic.
5.5 Because this document is a standard guide, it is intended to educate those who are involved in laboratory operation, quality system development and maintenance, reference material development, and accreditation of laboratory operations within the scope of a quality system. It must be understood by all parties that the elements of this guide discuss optional practices having numerous choices for accomplishment and documentation. However, this guide does not constitute requirements for assessment and accreditation. An obvious example is statistical evaluation for consensus value and uncertainty calculations, which can take many forms with no single, correct choice for any given case.
5.6 When using this guide, CRM developers will set goals for the material under development, such as target uncertainties for homogeneity and for overall coverage intervals for assigned values. These choices are based on the intended uses of a CRM. The material, property values, and their uncertainties may or may not meet the set goals...
SCOPE

It explains the contents of certificates of analysis for CRMs and product information documents for RMs, based on existing international standards and guides. It briefly touches on the minimum requirements for a label attached to the CRM/RM unit or unit container and to the package containing the unit or unit container.
1.2 This guide provides some basic guidance on calculation of consensus values and uncertainty estimates for CRMs and RMs with examples of approaches commonly used by national metrology institutes and suggestions for sources of information.
1.3 Units—The values stated in SI units are to be regarded as the standard, whenever applicable. Values can be traceable to other higher-order reference systems, including Rockwell Hardness, pH, and other systems defined by an international standard or peer-reviewed publication.

This document sets out the basic methods for sampling copper, lead, zinc and nickel concentrates from moving streams and stationary lots, including stopped-belt sampling, to provide samples for chemical analysis, physical testing and determination of moisture content, in accordance with the relevant International Standards. Where the concentrates are susceptible to significant oxidation or decomposition, a common sample that is sufficiently representative, i.e. unbiased and sufficiently precise, is used for moisture determination and chemical analysis to eliminate bias (see ISO 10251). Any large agglomerates (>10 mm) present in the primary sample are crushed prior to further sample processing. Sampling of concentrates in slurry form is specifically excluded from this document. Stopped-belt sampling is the reference method for collecting concentrate samples against which mechanical and manual-sampling procedures can be compared. Sampling from moving streams is the preferred method. Both falling-stream and cross-belt samplers are described. Sampling from stationary lots is used only where sampling from moving streams is not possible. The procedures described in this document for sampling from stationary lots only minimize some of the systematic sampling errors.

SIGNIFICANCE AND USE
5.1 This practice is primarily to be used to dry samples for determination of total mercury. It should not be used for determination of sample moisture content. Most sample preparation methods prescribe drying samples at 105 °C, until a constant mass is obtained. The moisture content is determined as the percent mass loss on drying. Because mercury and some of its compounds are volatile at 105 °C, samples for mercury determination shall be dried at 60 °C (see Practice E877, ISO 9599, ISO 12743, and ISO 10251).
5.2 It is assumed that all who use this practice will be trained analysts capable of performing skillfully and safely. It is expected that work will be performed in a properly equipped laboratory under appropriate quality control practices such as those described in Guide E882.
