ČSN EN IEC 60601-2-76 The minimum safety requirements specified in this particular standard are considered to provide for a practical degree of safety in the operation of low energy ionized gas haemostasis equipment. This particular standard amends and supplements IEC 60601-1:2005 and IEC 60601-1:2005/AMD1:2012 Medical electrical equipment - Part 1: General requirements for basic safety and essential performance, hereinafter referred to as the general standard (see 201.1.4). The requirements are followed by specifications for the relevant tests. A "Particular guidance and rationale" section giving some explanatory notes, where appropriate, about the more important requirements is included in Annex AA. Clauses or subclauses for which there are explanatory notes in Annex AA are marked with an asterisk (*). It is considered that knowledge of the reasons for these requirements will not only facilitate the proper appli-cation of the standard but will, in due course, expedite any revision necessitated by changes in clinical practice or as a result of developments in technology. However, this annex does not form part of the requirements of this document.

ČSN EN IEC 62087-7 This part of IEC 62087 specifies the determination of the power consumption of computer monitors including, but is not limited to, those with CRT, LCD, PDP or OLED technologies. Computer monitors that include touch screen functionality are included in the scope of this document. This document is limited to computer monitors that are powered from a main power source other than a battery. Computer monitors that are powered from a battery source are not covered by this document. However mains-powered computer monitors may include any number of auxiliary batteries. Computer monitors connected by digital inputs such as DisplayPort, HDMI, DVI, or by analogue VGA input, are considered in this document. This document does not apply to network- and wirelessly connected computer monitors. A computer monitor is a display device that does not include a TV tuner and is intended to be used to display the video signals from a computer. These video signals are produced from software programs that are operating within the computer and can consist of static and moving images. As such, test procedures using static patterns, dynamic video and web-based video are specified. The test methods specified in this document can be applied to computer monitors of any size, however, this document is not applicable to specialized monitors associated with medical equipment, publishing and other professional, commercial or industrial uses. The various modes of operation that are relevant for measuring power consumption are also defined. The measuring conditions in this document represent the normal use of the equipment and can differ from specific conditions, for example as specified in safety standards.

ČSN EN 15587 This European Standard specifies the term Besatz (impurities) and describes methods for the determination of its components. The term Besatz is used as a parameter for certain quality aspects in common wheat (Triticum aestivum L.), durum wheat (Triticum durum Desf.), rye (Secale cereale L.), triticale (Triticosecale Wittmack spp) and feed barley (Hordeum vulgare L.).

ČSN EN 14243-2 This standard provides test methods for the determination of the particle size distribution of granulates and powders, produced from all categories of end-of-life tyres at all steps of the treatment processes as well as for the determination of impurities (including free steel and free textile content). The methods described in this standard include sample collection and the preparation of a representative sample based on a sampling plan for the purpose of determining particle size distribution and impurities.

ČSN EN ISO 11296-7 This document, in conjunction with ISO 11296-1, specifies requirements and test methods for pipes which are formed on site by spirally winding and jointing a pre-manufactured profiled plastics strip, or a profiled plastics strip and integral locking joiner strip, and used for the renovation of underground non-pressure drainage and sewerage networks. It applies to spirally-wound pipes of fixed or variable diameter made of profiled plastics strips, with or without steel stiffening elements, and installed by one of two methods. The first method employs a dedicated winding machine in front of the open end of an existing pipeline, e.g. in a manhole. The pipes thus formed are simultaneously inserted into the existing pipeline by the winding forces, and by certain techniques can also be expanded in diameter after or during insertion. The second method employs a dedicated winding machine which forms the pipe as it traverses the existing pipeline from one manhole to the next. It applies to profiled plastics strips of unplasticized poly(vinyl chloride) (PVC U) with integral locking mechanism, or of high density polyethylene (HDPE) with integrally welded joints.

ČSN EN 17181 This document specifies a procedure for determining the degree of aerobic degradation of fully formulated lubricants. The organic material in a fully formulated lubricant is exposed in a synthetic aqueous medium under laboratory conditions to an inoculum from activated sludge. Biodegradation resulting in mineralisation of the organic material can be determined by measuring released CO2 in a total organic carbon (TOC) analyser. In contrast to existing test methods measuring released CO2 this method uses a precise preparation procedure for non-water soluble organic material. The above mentioned method applies to fully formulated lubricants which a) are water-soluble, non-water soluble or emulsifiable, and b) are not toxic and not inhibitory to the test microorganisms at the test concentration. The presence of inhibitory effects is determined as specified in this document. This test method is focused on fresh water as test medium. Tests in sea water are currently not included in this method, but may be introduced later.

ČSN EN ISO 11930 This document specifies a procedure for the interpretation of data generated by the preservation efficacy test or by the microbiological risk assessment, or both, when evaluating the overall antimicrobial protection of a cosmetic product. It comprises: - a preservation efficacy test; - a procedure for evaluating the overall antimicrobial protection of a cosmetic product that is not considered low risk, based on a risk assessment described in ISO 29621. The preservation efficacy test is a reference method to evaluate the preservation of a cosmetic formulation. It is applicable to cosmetic products in the marketplace. This test does not apply to those cosmetic products for which the microbiological risk has been determined to be low according to Annex A and ISO 29621. This test is primarily designed for water-soluble or water-miscible cosmetic products and can be used with modification to test products in which water is the internal (discontinuous) phase. NOTE: This test can be used as a guideline to establish a development method during the development cycle of cosmetic products. In this case, the test can be modified or extended, or both, for example, to make allowance for prior data and different variables (microbial strains, media, incubation conditions exposure time, etc.). Compliance criteria can be adapted to specific objectives. During the development stage of cosmetic products, other methods, where relevant, can be used to determine the preservation efficacy of formulations.
