General Information
Frequently Asked Questions
ICS 73.060.01 is a classification code in the International Classification for Standards (ICS) system. It covers "Metalliferous minerals in general". The ICS is a hierarchical classification system used to organize international, regional, and national standards, facilitating the search and identification of standards across different fields.
There are 20 standards classified under ICS 73.060.01 (Metalliferous minerals in general). These standards are published by international and regional standardization bodies including ISO, IEC, CEN, CENELEC, and ETSI.
The International Classification for Standards (ICS) is a hierarchical classification system maintained by ISO to organize standards and related documents. It uses a three-level structure with field (2 digits), group (3 digits), and sub-group (2 digits) codes. The ICS helps users find standards by subject area and enables statistical analysis of standards development activities.
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...
