This document describes the basic requirements for the design and application of explosion suppression systems. This document also specifies test methods for evaluating the effectiveness and the scale up of explosion suppression systems against defined explosions. This document covers:
— general requirements for explosion suppression system components;
— evaluating the effectiveness of an explosion suppression system;
— evaluating the scale up of an explosion suppression system;
— development and evaluation of design tools for explosion suppression systems;
— installation, operation and maintenance instructions for an explosion suppression system.
This document is applicable only to explosion suppression systems intended for the protection of closed, or essentially closed, enclosures in which an explosion could result as a consequence of ignition of an explosible mixture, e.g. dust-air, gas(vapour)-air, dust-gas(vapour)-air and mist-air.
This document is not applicable for explosions of materials listed below, or for mixtures containing some of those materials:
— unstable materials that are liable to dissociate;
— explosive materials;
— pyrotechnic materials;
— pyrophoric materials.

This European Standard specifies requirements for design, construction, testing and marking of
handheld, portable and transportable vacuum cleaners and dust collectors, including their
accessories, constructed to Group II categories 2G and 3G and to Group II categories 2D and 3D,
intended for the collection of combustible or non-combustible dusts and flammable or non260
flammable liquids in potentially explosive atmospheres. A potentially explosive atmosphere may be
generated by the equipment during its intended use. It covers equipment driven by electricity and
by pneumatic power.

This European Standard deals with all significant hazards, hazardous situations and events
relevant to vacuum cleaners and dust collectors, when they are used as intended and under
conditions of misuse which are reasonably foreseeable by the manufacturer.

 Typical applications for the concerned equipment are:

 - Collection of dust produced by machinery at the point of generation
 - General housekeeping around machinery and of working areas
 - And/or collection of spills.

For other specific applications a specific assessment shall be performed.

This European Standard does not cover equipment used to collect toxic dusts where there is a
health risk if dust passes through the filter element. This European Standard does not cover either
the collection of dusts which have explosive and unstable properties (UN transport class 1, class
4.1 and class 5.2).

This European Standard covers vacuum cleaners with an internal dust loaded volume of maximum
200 liters

This European Standard does not apply to pumps, where the inlet nozzle is submerged into a
liquid, and all conveying applications.

This European Standard does not apply to Group I vacuum cleaners and dust collectors for mining.

For an easier readability, all types of equipment concerned by this standard are referred as
“Vacuum cleaner” in this document.

NOTE Where undated references are used in the body of the standard the latest edition
applies

This document contains terms and definitions for CBRNE (chemical, biological, radiological, nuclear, explosive) applications.
Common understanding and communication is important in the implementation of an effective CBRNE response and this communication will be most effective if there is common understanding of the terms used. Many of the terms and definitions listed here have been widely used for many years, while others are the result of cross-cutting experience of areas of CBRNE. The gradual evolution of our understanding of CBRNE and response measures means that CBRNE terminology will continue to develop.
This document is dedicated to first responders, administrative staff, industry representatives and researchers.

This document specifies a method for the determination of the oxygen content in bio-based products using an elemental analyser. The scope is limited to products containing elements C, H, O, N, Cl, Br and I without F, representing at least 95 % of the composition of the product to be analysed.
NOTE 1 Bio-based materials can contain inorganic components. Oxygen in these inorganic components is not bio-based but will nevertheless contribute to the amount of oxygen determined by the following prescribed methods and therefore influence the results in terms of oxygen content.
NOTE 2 Although this document has been drafted for the purpose of the determinations dealing with bio-based content, it can be also used as a standalone standard for determination of oxygen in organic compounds.
NOTE 3 For the purposes of this document, the term “% (m/m)” is used to represent the mass (μ) of a material.

This document specifies two methods for the determination of the thermal stability of products and compounds based on vinyl chloride homopolymers and copolymers (referred to simply as PVC in the following text) by the extent of the discoloration that occurs when they are exposed, in the form of sheet, to elevated temperatures. The two methods are:

—    Method A: Oil-bath method;

—    Method B: Oven method.

These methods are particularly applicable to the determination of the resistance of PVC to degradation by heat, as assessed by the change in colour after different times of heating under standardized conditions. The results are comparative only, and can be unsatisfactory when coloured PVC materials are tested.

The stability times given by the two methods might not be similar and cannot be used for direct-comparison purposes.

This document defines a banding band, style Z, for terminating individual and/or overall cable screens to cable outlets. The bands delivered in flat condition F (see Clause 6) which need to be double wrapped prior to their installation. The bands delivered in condition C (see Clause 6) are factory pre-double wrapped and ready for installation.

This document specifies the requirements for an intermediate coat to be applied over a primer for aerospace applications and with a topcoat for aerospace applications on top.

The properties specified in this standard are obtained on defined aluminium alloy test pieces prepared in accordance with EN 3837 and EN ISO 3270 and painted with primer listed in Table 1. Topcoat listed in Table 1 is to be applied on intermediate coat to this standard. The ability of the material to be used for a specific application (e.g. alternative substrate, alternative primer, specific drying conditions, etc.) should be determined by supplementary tests to confirm that the requirements of this standard are met.

This part of ISO 19085 gives the safety requirements and measures for stationary four sided moulding machines with a maximum working width of 350 mm and a maximum speed of the integrated workpiece feed of 200 m/min, with electrical and/or electronic control system, hereinafter referred to as “machines” designed to cut solid wood and materials with similar physical characteristics to wood (see ISO 19085-1:2017, 3.2).

It deals with all significant hazards, hazardous situations and events as listed in Clause 4 relevant to machines, when operated, adjusted and maintained as intended and under the conditions foreseen by the manufacturer including reasonably foreseeable misuse. Also, transport, assembly, dismantling,
disabling and scrapping phases are taken into account.

NOTE: For relevant but not significant hazards, e.g. sharp edges of the machine frame, see ISO 12100:2010.

It is also applicable to machines fitted with one or more of the following devices / additional working units, whose hazards have been dealt with:

This part of ISO 19085 does not deal with any hazards related to:

a) in-feed devices other than in-feed hopper and in-feed loading table (magazines, etc.);
NOTE: For mechanical in-feed devices which also prevent access to the in-feed opening, see 6.6.4.
b) out-feed devices (e.g. mechanical handling systems) except for hazards related to ejection from the machine due to climb cutting
c) single machine being used in combination with any other machine (as part of a line);
It is not applicable to machines intended for use in potentially explosive atmosphere and to machines manufactured prior to its publication.

This standard shall be read with EN 50186-1 "Operation of electrical installations - Part 1: General requirements" and contains national annexes which need to be used on this subject.

This European Standard specifies the general requirements for central power supply systems for an independent energy supply to essential safety equipment. This standard covers systems that are permanently connected to AC supply voltages not exceeding 1 000 V and use batteries as an alternative power source.

Central safety power supply systems are intended to ensure energy supply to emergency escape lighting in the event of normal supply failure and may be suitable for energising other essential safety equipment, for example:
- electric circuits of automatic fire extinguishing installations;
- paging systems and signalling safety installations;
- smoke extraction equipment;
- carbon monoxide warning systems;
- special safety installations related to specific buildings, e.g. high-risk areas.

The power supply of CPS should be dedicated only to the essential safety equipment, and not for other typeof loads such as general purpose IT or industrial systems etc.

Combinations of the aforementioned safety equipment types and / or non-safety equipment loads are permitted together on the same central safety power supply system providing the availability for safety equipment loads is not impaired. A fault occurring in a circuit should not cause the interruption in any other circuit used to supply safety equipment.

Schematic representations of typical central safety power supply equipment are depicted in Clause 4.

Power supply systems for fire alarm equipment that are covered by EN 54 (series) are excluded.

This document specifies a process for a medical laboratory to identify and manage the risks to patients, laboratory workers and service providers that are associated with medical laboratory examinations.

This document does not specify acceptable levels of risk.

This document does not apply to risks from post-examination clinical decisions made by healthcare providers.

This document does not apply to the management of risks affecting the medical laboratory enterprise that are addressed by ISO 31000, such as business, economic, legal, and regulatory risks.

NOTE   International, national, or regional regulations or requirements may also apply to specific topics covered in this international standard

This part of ISO 1833 specifies a method, using sulfuric acid, to determine the mass percentage of chlorofibres and certain other fibres, after removal of non-fibrous material, in textiles made of mixtures of

cotton, viscose, cupro, modal, lyocell, acetate, triacetate, polyamide, polyester, elastomultiester, certain acrylic and certain modacrylic fibreswith

chlorofibres based on homopolymers of vinyl chloride, polypropylene, elastolefin, melamine and polypropylene/polyamide bicomponent.

The modacrylics concerned are those which give a limpid solution when immersed in concentrated sulfuric acid (ρ = 1,84 g/ml at 20°C).]

This method can be used, particularly in place of the methods described in ISO 1833‑12 and ISO 1833‑13, in all cases where a preliminary test shows that the chlorofibres do not dissolve completely either in dimethylformamide or in the azeotropic mixture of carbon disulfide and acetone.

This document specifies a method, by determining the nitrogen content, to calculate the proportion of each component, after the removal of non-fibrous matter, in textiles made of mixtures of

—    jute

with animal fibres.

The animal-fibre component may consist solely of hair or wool, or of any mixtures of the two.

This part of ISO 1833 is not applicable to products in which dyestuffs or finishes contain nitrogen.

NOTE          Because this method differs in principle from the general method based on selective solubility set out in ISO 1833‑1, it is given in a form that is complete in itself.

This International Standard establishes general rules for the compilation of performance test schedules for complete, filled transport packages intended for use within any distribution system except for the packages used for dangerous goods.

This part of ISO 105 describes the grey scale for determining staining of adjacent fabrics in colour fastness tests, and its use. A precise colorimetric specification of the scale is given as a permanent record against which newly prepared working standards and standards that may have changed can be compared.

This document specifies a method for the measurement of 210Po in all types of waters by alpha spectrometry.

The method is applicable to test samples of supply/drinking water, rainwater, surface and ground water, marine water, as well as cooling water, industrial water, domestic, and industrial wastewater after proper sampling and handling, and test sample preparation. A filtration of the test sample is necessary.

The detection limit depends on the sample volume, the instrument used, the background count rate, the detection efficiency and the chemical yield. The method described in this document, using currently available alpha spectrometry apparatus, has a detection limit of approximately 5 mBq.l-1, which is lower than the WHO criteria for safe consumption of drinking water (100 mBq·l-1). This value can be achieved with a counting time of 24 hours for a sample volume of 500 ml.

The method described in this document is applicable in the event of an emergency situation.

The analysis of 210Po adsorbed to suspended matter is not covered by this method.

It is the user’s responsibility to ensure the validity of this test method for the water samples tested.

If suspended material has to be removed or analysed, filtration at 0,45 μm is recommended. The analysis of the insoluble fraction requires a mineralization step that is not covered by this document (see NF M 60‑790‑4[13]). In this case, the measurement is made on the different phases obtained. The final activity is the sum of all the measured activity concentrations.
