This document establishes a set of common definitions related to women's entrepreneurship, such as those for women-owned business and women-led business. This document also defines women-led cooperatives and women-led informal enterprises. These definitions can be used, for example, in women's economic empowerment programmes (such as procurement and trade programmes) and for the collection of internationally comparable data on women's entrepreneurship (including the impact on local and national economies). This document also provides criteria for evaluating important factors related to these definitions, such as ownership, management, and control, as well as how to handle dilution by investment. NOTE If an enterprise cannot be categorized according to the definitions given in this document, it does not necessarily mean that the enterprise is male-owned or male-led. This document does not provide recommendations on how to initiate programmes based on the definitions and criteria, for example on public procurement. In addition, this document does not address issues such as how to promote conformity assessment.

This document provides guidance on developing and using a measurement model and also covers the assessment of the adequacy of a measurement model. The document is of particular interest to developers of measurement procedures, working instructions and documentary standards. The model describes the relationship between the output quantity (the measurand) and the input quantities known to be involved in the measurement. The model is used to obtain a value for the measurand and an associated uncertainty. Measurement models are also used in, for example, design studies, simulation of processes, and in engineering, research and development. This document explains how to accommodate in a measurement model the quantities involved. These quantities relate i) to the phenomenon or phenomena on which the measurement is based, that is, the measurement principle, ii) to effects arising in the specific measurement, and iii) to the interaction with the artefact or sample subject to measurement. The guidance provided is organised in accordance with a work flow that could be contemplated when developing a measurement model from the beginning. This work flow starts with the specification of the measurand (clause 6). Then the measurement principle is modelled (clause 7) and an appropriate form of the model is chosen (clause 8). The basic model thus obtained is extended by identifying (clause 9) and adding (clause 10) effects arising from the measurement and the artefact or sample subject to measurement. Guidance on assessing the adequacy of the resulting measurement model is given in clause 12. The distinction between the basic model and the (complete) measurement model in the work flow should be helpful to those readers who already have a substantial part of the measurement model in place, but would like to verify that it contains all effects arising from the measurement so that it is fit for purpose. Guidance on the assignment of probability distributions to the quantities appearing in the measurement model is given in JCGM 100:2008 and JCGM 101:2008. In clause 11, this guidance is supplemented by describing how statistical models can be developed and used for this purpose. When using a measurement model, numerical problems can arise including computational effects such as rounding and numerical overflow. It is demonstrated how such problems can often be alleviated by expressing a model differently so that it performs well in calculations. It is also shown how a reformulation of the model can sometimes be used to eliminate some correlation effects among the input quantities when such dependencies exist. Examples from a number of metrology disciplines illustrate the guidance provided in this document.

This document does not apply to treatment units requiring major sewer infrastructure. Inputs are primarily faecal sludge derived from human excreta and can include additional substances at the discretion of the manufacturer. This document does not specify the characteristics of the faecal sludge (e.g. COD, BOD, moisture content, etc.) and which forms of the additional inputs (e.g. food waste) are treated within the unit. These inputs are defined by the manufacturer as well as the input characteristics which meet the requirements specified in this document. This document addresses: — the performance, safety, operability, and maintainability of the treatment unit, — the protection of human health and the environment, — safety aspects of the treatment unit's solid, liquid, and gaseous outputs, — noise and odour outputs of the treatment unit. This document specifies minimum requirements of all types of outputs from the treatment unit. It does not specify or mandate the quality of resources recovered as these are highly dependent on the local (e.g. economic, social) context. Any resources produced and consumed internally to the process itself are outside the scope of this document. Similarly, with the exception of pathogen requirements, the quality and value of any resource recovery and reuse products derived from the treatment unit are outside the scope of this document. Apart from the requirement for energy independence under manufacturer specified input conditions during steady-state operation, this document does not set performance targets with respect to the amount or type of energy or resources to recover and/or use locally. This document does not address transportation and any intermediary processes required to supply the treatment unit with the defined inputs. Provisions of this document apply to the treatment unit according to its unit boundaries, i.e. within the process chain beginning with its specified inputs and ending with its outputs. Some of the considerations on sustainability of the treatment unit are highlighted in Annex B.

ISO/IEC Guide 98-4:2012 provides guidance and procedures for assessing the conformity of an item (entity, object or system) with specified requirements. The item might be, for example, a gauge block, a grocery scale or a blood sample. The procedures can be applied where the following conditions exist: the item is distinguished by a single scalar quantity (a measurable property) defined to a level of detail sufficient to be reasonably represented by an essentially unique true value; an interval of permissible values of the property is specified by one or two tolerance limits; the property can be measured and the measurement result expressed in a manner consistent with the principles of the GUM, so that knowledge of the value of the property can be reasonably described by (a) a probability density function, (b) a distribution function, (c) numerical approximations to such functions, or (d) a best estimate, together with a coverage interval and an associated coverage probability. The procedures developed in this document can be used to realize an interval, called an acceptance interval, of permissible measured values of the property of interest. Acceptance limits can be chosen so as to balance the risks associated with accepting non-conforming items (consumer's risk) or rejecting conforming items (producer's risk). Two types of conformity assessment problems are addressed. The first is the setting of acceptance limits that will assure that a desired conformance probability for a single measured item is achieved. The second is the setting of acceptance limits to assure an acceptable level of confidence on average as a number of (nominally identical) items are measured. Guidance is given for their solution. This document contains examples to illustrate the guidance provided. The concepts presented can be extended to more general conformity assessment problems based on measurements of a set of scalar measurands. The audience of this document includes quality managers, members of standards development organizations, accreditation authorities and the staffs of testing and measuring laboratories, inspection bodies, certification bodies, regulatory agencies, academics and researchers.

This International Standard specifies the minimum requirements for billing of all consumption-based utility network services to domestic customers. It covers the processes required to produce the bill and to deal with issues that arise after the bill has been sent, as well as the content of the billing document or statement. This International Standard is applicable to utility network services that are unmetered, metered at the point of delivery or metered remotely (e.g. on the supplier's own premises), and it covers any unmetered or unmeasured charges appearing on the same bill as metered or measured charges, as well as flat rate charges. NOTE 1 Utility network services include electricity supply, water, sanitation, gas supply, district heating and communications. NOTE 2 The requirements given in this International Standard are also applicable to other consumers who are legally entitled to use the service provided by the supplier, except where in order to comply with privacy or data protection requirements, it is necessary for the supplier to obtain the authority of the registered customer before dealing with another consumer on billing matters. This International Standard does not cover pricing, except for a requirement to provide information to customers. It is only applicable to billing for consumption-based utility network services and it applies to all bills or statements for utility network services where there is an ongoing account relationship between the customer and the supplier, regardless of the payment method used. NOTE 3 This includes bills for metered consumption, bills where a formula is used to estimate consumption (e.g. water bills based on the number of persons per household or the size of the house), or where a flat rate fee is charged regardless of consumption (e.g. telephony or internet bills where the tariff allows unlimited usage). It also applies to prepayment customers, where a bill or account from the supplier is necessary to enable the customer to reconcile the amount paid in advance with the cost of consumption, or where the customer expects to receive a bill based on point of sale or other advertising (e.g. mobile telephony and energy metering) where codes, keys, electronic dongles or electronic cards are used to load and reload the service and to indicate what was purchased. NOTE 4 Services that are not billed [e.g. mobile telephony paid for by pre-purchased SIM (Subscriber Identity Module) cards that are unmetered] and services that are funded directly by the taxpayer without bills being issued are not covered by this International Standard. NOTE 5 Many of the key principles in this International Standard also apply to all forms of billing, and suppliers are therefore encouraged to adopt the relevant requirements in this International Standard for billing of other services.

ISO 20121:2012 specifies requirements for an event sustainability management system for any type of event or event-related activity, and provides guidance on conforming to those requirements. ISO 20121:2012 is applicable to any organization that wishes to: establish, implement, maintain and improve an event sustainability management system; ensure that it is in conformity with its stated sustainable development policy; demonstrate voluntary conformity with ISO 20121:2012 by first party (self-determination and self-declaration), second party (confirmation of conformance by parties having an interest in the organization, such as clients, or by other persons on their behalf), or an independent third party (e.g. a certification body). ISO 20121:2012 has been designed to address the management of improved sustainability throughout the entire event management cycle.

ISO/IEC Guide 98-3:2008/Suppl.2:2011 is concerned with measurement models having any number of input quantities and any number of output quantities. The quantities involved might be real or complex. Two approaches are considered for treating such models. The first approach is a generalization of the GUM uncertainty framework. The second is a Monte Carlo method as an implementation of the propagation of distributions. Appropriate use of the Monte Carol method would be expected to provide valid results when the applicability of the GUM uncertainty framework is questionable. For a prescribed coverage probability, ISO/IEC Guide 98-3:2008/Suppl.2:2011 can be used to provide a coverage region for the output quantities of a multivariate model, the counterpart of a coverage interval for a single scalar output quantiy. The provision of coverage regions includes those taking the form of a hyper-ellipsoid or a hyper-rectangle. These coverage regions are produced from the results of the two approaches described here. A procedure for providing an approximation to the smallest coverage region, obtained from results provided by the Monte Carol method, is also given. Detailed examples to illustrate the guidance are provided.
