Nuo chemikalų sauganti apsauginė apranga. Klasifikavimas, ženklinimas ir veiksmingumo reikalavimai. 6 dalis. Parinkimo, naudojimo, priežiūros ir taisymo nurodymai (ISO/DIS 16602-6:2025)

This document addresses the selection, use, care and maintenance (SUCAM) of chemical protective clothing (CPC). This guidance document is primarily intended for users, specifiers and others with responsibility for the procurement and provision of chemical protective clothing. It is also intended to be used by manufacturers in their dialogue with the users of PPE. This guidance document is intended to clarify the inter-relationship between this ISO 16602 series of standards and its modular approach, ISO 17723-1 but also how this links to the old classification of CPC. These guidelines are intended to assist users and specifiers in selecting the correct type of CPC for the task to be performed, and to help them ensure it is used according to the manufacturer's instructions to provide adequate chemical protection (including solids, airborne particles, aerosols, liquids, and gases (including radioactive contamination)) during its entire lifetime. Lifetime and effectiveness of protective clothing depend largely on care and maintenance. When cleaning, disinfection and end-of-life disposal are considered the environmental impact should also be taken into account. To assist the users of products covered under this document, this document provides descriptions of referenced test methods, guidelines for conducting hazard and risk assessments and suggested performance levels for certain applications. It is not the intent of this document to address all situations. NOTE Although this document has been created as a stand-alone document covering ISO 16602-1 through ISO 16602-5, it is strongly recommended to read this guidance in conjunction with ISO 16602-1 (if not the other parts) to understand the detail of the requirements.

Nuo chemikalų sauganti apsauginė apranga. Klasifikavimas, ženklinimas ir veiksmingumo reikalavimai. 1 dalis. Bendrieji reikalavimai (ISO/DIS 16602-1:2025)

This document specifies minimum performance classification and labelling requirements for protective clothing designed to provide protection against: - specified chemicals in the workplace, and - unidentified chemicals in emergency situations. Protective clothing against chemicals including solids, airborne particles, aerosols, liquids, and gases is addressed by this document. Protective clothing items covered by this document include full body and partial body. The area of protection is denoted in the marking requirements. The ISO 16602 series allows for a modular approach. This document sets the general requirements and the rules for applying the modular approach. The other parts focus on requirements and classification from design, chemical, physical properties and full garment testing perspectives. The seams, joins and assemblages attaching the components (including accessories) are included within the scope of this series of standards. ISO 16602-6 provides a Selection, Care and Maintenance guide to help the end-user selection process. Chemicals such as violently air sensitive reagents, unstable explosives and cryogenic liquids have not been considered since protection against these additional hazards is beyond the scope of this standard. Particulate protection is limited to physical penetration of the particulates only; permeation of solids is not considered. This document does not address components such as gloves, boots, eye/face protection devices and respiratory protective devices as their performance criteria are given in other standards. However, when these components are an integral part of the protective clothing ensemble or are tested as part of an ensemble, supplementary requirements may be provided in this standard. This document does not specifically address non-chemical hazards, such as biological and infective agents, thermal (flame, heat or cold) hazards, explosive hazards, and ionizing radiation hazards as specific requirements are covered by other relevant standards. The type of equipment specified in this series of standards is not intended for total immersion in liquids. However, additional protection may be integrated as a specific module based on the respective standard (e.g. meeting both ISO 16602-1 & ISO 11612 in a multi-risk suit). It is not the intent of this series of documents to be exhaustive and address all situations.

Nuo chemikalų sauganti apsauginė apranga. Klasifikavimas, ženklinimas ir veiksmingumo reikalavimai. 2 dalis. Fizikiniai bandymo metodai, klasifikavimas ir reikalavimai (ISO/DIS 16602-2:2025)

This document specifies the performance classification and test methods for materials used in chemical protective clothing, including gloves and footwear. The gloves and boots should have the same minimum chemical protective barrier performance requirements as the fabric when an integral part of the clothing. This is a reference standard to which chemical protective clothing performance standards may refer in whole or in part, but this standard is not exhaustive in the sense that other parts of ISO 16602 may well require testing according to test method standards which are not included in this standard. While these performance levels are intended to relate to the usage to which the chemical protective clothing is to be put, it is essential that the chemical protective clothing manufacturer or supplier indicates the intended use of the protective clothing. It is similarly important that the user (specifier) carries out a risk assessment in order to establish the correct protective performance levels for the intended task.

Komentavimo iki data 2025-09-09

Juslinė analizė. Metodika. Testas du iš trijų (ISO/DIS 10399:2025)

ISO 10399 specifies a procedure for determining whether a perceptible sensory difference or similarity exists between samples of two products. The method is a forced-choice procedure. The method is applicable whether a difference exists in a single sensory attribute or in several attributes. The method is statistically less efficient than the triangle test (described in ISO 4120) but is easier to perform by the assessors. The method is applicable even when the nature of the difference is unknown (i.e. it determines neither the size nor the direction of difference between samples, nor is there any indication of the attribute(s) responsible for the difference). The method is applicable only if the products are fairly homogeneous. The method is effective for a) determining that either a perceptible difference results (duo-trio testing for difference), or a perceptible difference does not result (duo-trio testing for similarity) when, for example, a change is made in ingredients, processing, packaging, handling or storage, and b) for selecting, training and monitoring assessors. Two forms of the method are described: - the constant-reference technique, used when one product is familiar to the assessors (e.g. a sample from regular production); - the balanced-reference technique, used when one product is not more familiar than the other.

Komentavimo iki data 2025-09-04

Radiacinė sauga. Pamatinės pulsuojamosios spinduliuotės charakteristikos. 1 dalis. Fotoninė spinduliuotė (ISO/DIS 18090-1:2025)

ISO/TS 18090-1:2015 is directly applicable to pulsed X-radiation with pulse duration of 0,1 ms up to 10 s. This 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. ISO/TS 18090-1:2015 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. 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. ISO/TS 18090-1:2015 does not define new radiation qualities. Instead, it uses those radiation qualities specified in existing ISO and IEC standards. This part of ISO/TS 18090 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 part of ISO/TS 18090 are met. Therefore, not all reference pulsed X-ray facilities can produce pulses covering the same parameter ranges.
