ISO 8820-3:2015 specifies fuse-links with tabs (blade-type) Type C (medium), Type E (high current), and Type F (miniature) for use in road vehicles. It establishes, for these fuse-link types, the rated current, test procedures, performance requirements, and dimensions.

ISO 8820-3:2015 is applicable for fuse-links with a rated voltage of 32 V or 58 V, a current rating of ≤100 A, and a breaking capacity of 1 000 A intended for use in road vehicles.

ISO 8820-3:2015 is intended to be used in conjunction with ISO 8820‑1 and ISO 8820‑2. The numbering of its clauses corresponds to that of ISO 8820‑1, whose requirements are applicable, except where modified by requirements particular to this part of ISO 8820.

This document specifies the requirements for the safety of persons and property, provides guidance for the protection of the environment and establishes procedures for the operation, maintenance and repair of refrigerating systems and the recovery of refrigerants. The term “refrigerating system” used in this document includes heat pumps. This part of EN 378 specifies the classification and selection criteria applicable to refrigerating systems. These classification and selection criteria are used in Parts 2, 3 and 5. This document applies to: a) refrigerating systems, stationary or mobile, of all sizes except to vehicle air conditioning systems covered by a specific product standard e.g. [7] b) secondary cooling or heating systems; c) the location of the refrigerating systems; d) replaced parts and added components after adoption of this document if they are not identical in function and in the capacity. Systems using refrigerants other than those listed in Part 5 of this standard are not covered by this document. Clause 7 specifies how to determine the refrigerant quantity safety limit in a given space, which, when exceeded, requires additional protective measures to reduce the risk. This document is not applicable to refrigerating systems which were manufactured before the date of its publication as a European Standard except for extensions and modifications to the system which were implemented after publication. This document is applicable to new refrigerating systems, extensions or modifications of already existing systems, and for existing stationary systems, being transferred to and operated on another site. This document also applies in the case of the conversion of a system to another refrigerant type, in which case conformity to the relevant clauses of Parts 1, 2, 3 and 5 of the standard is expected to be assessed. Product family standards dealing with the safety of refrigerating systems take precedence over horizontal and generic standards covering the same subject.

ISO 11135:2014 specifies requirements for the development, validation and routine control of an ethylene oxide sterilization process for medical devices in both the industrial and health care facility settings, and it acknowledges the similarities and differences between the two applications.

This International Standard defines terms related to quality assurance of culture media and reagents and specifies the requirements for the preparation of culture media and reagents intended for the microbiological analysis of food, animal feed, and samples from the food or feed production environment as well as all kinds of water. These requirements are applicable to all categories of culture media and reagents prepared for use in laboratories performing microbiological analyses. This document also sets criteria and describes methods for the performance testing of culture media and reagents. The document is applicable to end-users, commercial bodies, non-commercial bodies and labs preparing their own media. This covers all formats of culture media and reagents. The principles covered in this Standard, as described above, can be equally applied to the preparation, storage and performance testing of culture media and reagents (used in the intended analysis as described above) that are not captured in international Standards; this includes proprietary culture media, or other methods. The criteria for the performance of those culture media and reagents will be described within those other methods or in the manufacturers’ certificates.

This document is directly applicable to pulsed X-radiation with pulse duration of 0,1 ms up to 10 s. This range covers the whole range used in medical diagnostics at the time of publication. Some specifications may also be applicable for much shorter pulses; one example is the air kerma of one pulse. Such a pulse may be produced, e.g. by X-ray flash units or high-intensity femtosecond-lasers. Other specifications are not applicable for much shorter pulses; one example is the time-dependent behaviour of the air kerma rate. This may not be measurable for technical reasons as no suitable instrument is available, e.g. for pulses produced by a femtosecond-laser. This document specifies the characteristics of reference pulsed radiation for calibrating and testing radiation protection dosemeters and dose rate meters with respect to their response to pulsed radiation. At this point, it is only concerned with the characteristics of single pulses. Single pulses are the most difficult for dosemeters to measure. Determining the dose for repeated pulses is easier, but still more difficult than for continuous radiation, i.e. the performance of the dosemeters when measuring repeated pulses lies between these extremes. The radiation characteristics includes the following: a) time-dependent behaviour of the air kerma rate of the pulse; b) time-dependent behaviour of the X-ray tube high voltage during the pulse; c) uniformity of the air kerma rate within a cross-sectional area of the radiation beam; d) air kerma of one radiation pulse; e) air kerma rate of the radiation pulse; f) repetition frequency. This document does not define new radiation qualities, but uses those radiation qualities specified in existing ISO and IEC standards. Instead, this document gives the link between the parameters for pulsed radiation and the parameters for continuous radiation specifying the radiation qualities. It does not specify specific values or series of values for the pulsed radiation field but specifies only those limits for the relevant pulsed radiation parameters that are required for calibrating dosemeters and dose rate meters and for determining their response depending on the said parameters. The pulse parameters with respect to the phantom-related quantities were determined using conversion coefficients according to ISO 4037 (all parts). This is possible as the radiation qualities specified in existing ISO and IEC standards are used. A given reference pulsed X-ray facility is characterized by the parameter ranges over which the full specifications and requirements according to this document are met. Therefore, not all reference pulsed X-ray facilities can produce pulses covering the same parameter ranges.

This document specifies the design, testing and marking requirements for spring loaded pressure relief valves (PRV), for use in liquefied petroleum gas (LPG) cylinders of water capacity of 0,5 l up to and including 150 l. These PRVs can be either an integral part of a cylinder valve (see EN ISO 14245 [4] and EN ISO 15995 [5]) or a separate device.

This document applies to hearing aid fitting management (HAFM) services offered by hearing aid professionals (HAP) when providing benefit for their clients. The provision of hearing aids relies on the knowledge and practices of a hearing aid professional, to ensure the proper fitting and adequate service in the interest of the client with hearing loss. This document specifies general processes of HAFM from the client profile to the follow-up through administering, organising and controlling hearing aid fitting through all stages. It also specifies important preconditions such as education, facilities and systems that are required to ensure proper services. The focus of this document is the services offered to the majority of adult clients with hearing impairment. It is recognized that certain populations with hearing loss such as children, persons with other disabilities or persons with implantable devices can require services outside the scope of this document. This document generally applies to air conduction hearing aids and for the most part also to bone conduction devices. Hearing loss can be a consequence of serious medical conditions. Hearing aid professionals are not in a position to diagnose or treat such conditions. When assisting clients seeking hearing rehabilitation without prior medical examination, hearing aid professionals are expected to be observant of symptoms of such conditions and refer to proper medical care. Further to the main body of the document, which specifies the HAFM requirements and processes, several informative annexes are provided. Appropriate education of hearing aid professionals is vital for exercising HAFM. Annex A defines the competencies required for the HAFM processes. Annex B offers a recommended curriculum for the education of hearing aid professionals. Annex C is an example of an appropriate fitting room. Annex D gives guidance on the referral of clients for medical or other specialist examination and treatment. Annex E is a recommendation for important information to be exchanged with the client during the process of HAFM. Annex F is a comprehensive terminology list offering definitions of the most current terms related to HAFM. It is the intention that these annexes be helpful to those who wish to deliver HAFM of the highest quality.
