ČSN EN 17389 This document specifies the quality assurance and quality control procedures related to automated dust arrestment plant monitors. This document applies to two types of instruments commonly used for dust arrestment plant control purposes: - filter dust monitors that are configured in mass concentration units (e.g. mg/m3) and are used for dust arrestment control purposes; - filter leakage monitors that indicate a change in the emission levels or a change in the magnitude of the dust pulses created by the cleaning process of the dust arrestment plant. This document applies to instruments certified according to the requirements of EN 15859. This document provides information on the configuration, ongoing quality assurance (with automatic internal zero point and reference point checks) and annual surveillance tests of instruments. This ensures that the instrument is providing information to demonstrate that the dust arrestment plant is working correctly and controlling dust pollution to the required levels. The configuration of the alarm levels of filter dust monitors is performed by parallel measurements with the standard reference method in EN 13284-1. This document specifies the set-up of filter leakage monitors used to monitor a change in response caused by deterioration in the operation of the dust arrestment plant.

ČSN EN 17255-2 This document specifies the performance requirements on data acquisition and handling systems (DAHS) regarding implementation of the procedures defined in EN 17255-1 including - data acquisition; - data processing; - data storage; - data output; - generation of reports; - system functions; - data integrity; - documentation. This document supports the requirements of EN 14181 and legislation such as the IED and E-PRTR. It does not preclude the use of additional features and functions provided the minimum requirements of this document are met and that these features do not adversely affect data quality, clarity or access.

ČSN EN ISO 17512-2 This part of ISO 17512 specifies a rapid screening method for evaluating the habitat function of soils based on the avoidance behaviour of springtails. The test is a rapid method that reflects the bioavailability of contaminants in natural soils and substances spiked into soils to Folsomia candida. In both cases, it is possible to establish a dose-response-relationship. The avoidance behaviour of the springtails is the measurement endpoint of the test. This test is not intended to replace the Collembola reproduction test.

ČSN EN ISO 15473 This International Standard gives guidance on the selection and method of appropriate tests for the determination of biodegradation of organic chemicals in soil samples under anaerobic conditions. NOTE - If the method is intended for tests in the framework of the registration of chemicals, an OECD Guideline on soil degradation [20] gives useful guidance on additional test requirements.

ČSN EN ISO 17155 This International Standard specifies a test method for determining the activity of active aerobic, heterotrophic microbial biomass in soils. This method is applicable to the monitoring of soil quality and to the evaluation of the ecotoxic potential of soils and soil materials. It is also applicable for soils sampled along contamination gradients in the field and to soils that are contaminated experimentally in the field or in the laboratory.

ČSN EN ISO 11737-2 Tento dokument specifikuje obecná kritéria pro zkoušky sterility na zdravotnických prostředcích vystavených působení sterilizačního činidla sníženého oproti předpokládanému ošetření, které má být použito při běžné sterilizaci. Tyto zkoušky jsou určeny pro definování, validaci nebo udržování sterilizačního procesu.

ČSN EN ISO 21850-1 This document specifies stainless steel commonly used in manufacturing dental instruments. It is applicable to stainless steel materials used to manufacture either an entire instrument or a part of the instrument. It is applicable to single-use and reusable dental instruments, whether it is or it is not connected to a power-driven system. This document is not applicable to devices and instruments used long-term in the mouth of the patient (e.g. crown, bridges, implants) or to devices and instruments not made of stainless steel. It contains a current selection of stainless steels suitable for use in the manufacture of dental instruments.

ČSN EN ISO 7886-3 This document specifies the properties and performance of sterile single-use hypodermic syringes with an auto-disable syringe feature intended to deliver a fixed dose of vaccine immediately after filling. The syringes can be made of plastic, rubber or other materials and can be with or without needle and needle protection feature. This document does not specify the design of the auto-disable syringe feature. This document is not applicable to syringes for use with insulin (covered by ISO 8537), syringes for use with power-driven syringe pumps (covered by ISO 7886-2), reuse prevention syringes (covered by ISO 7886-4) or syringes designed to be prefilled (covered by the ISO 11040 series). It does not address compatibility with injection fluids/vaccines.
