This document specifies a test method for the determination of the crack formation temperature of
enamels for the chemical industry by subjecting enamelled steel specimens to thermal shock using cold
water.
The value of the crack formation temperature measured according to this test method does not apply to
the finished component (see Annex A). It is a parameter of vitreous and porcelain enamels for comparing
the relative quality of different enamel formulations.

This document provides guidance on addressing chemicals in the development of standards for
consumer-relevant articles. The aim is to minimize the impacts of chemicals of concern on human
health and the environment by complying with, complementing or going beyond legal obligations for these chemicals. Emphasis is given to chemicals in articles posing risks to human health during use. The
environmental dimension is considered, where feasible and where appropriate, for instance by
addressing environmental exposure or persistent or bio-accumulative chemicals.
The Guide is intended to assist in the development of normative provisions for chemicals, particularly in
those areas where specific regulatory provisions (e.g. limit values) for chemicals are absent and are not
envisaged to be implemented in the foreseeable future such as articles covered by the General Product
Safety Directive (2001/95/EC). In so doing, the Guide aims to facilitate the placing on the market of safe
products. In addition, these guidelines can assist those with a general professional interest in consumer
safety.
The Guide including the associated background information document presents a comprehensive
overview of approaches taken on chemicals in various legislative and voluntary tools. It is not intended
to override legal obligations. Both documents reflect the status as of April 2017.
Electrical and electronic equipment, and ICT products, are excluded from the scope as these products
fall under the lead of CENELEC and ETSI, respectively. Food contact materials, materials used in the
supply of drinking water, medical devices, and construction products are also excluded. This is because
comprehensive, detailed and specific regulation on chemicals in these products is either already
available or subject to consideration and debate; because specific approaches are required; or because
performance requirements are supposed to be addressed at national level; or a combination of all these.
Nonetheless, some of the guidance may be useful in areas excluded from the scope of the Guide.
It is envisaged that sector specific guides or standards dealing with chemical hazards in standards for
consumer-relevant articles, where available, should be used in conjunction with the present Guide.
NOTE The Bibliography includes relevant CEN sector guidance documents.

The objective of the CEN workshop is to describe a framework for a practical approach on measures to achieve "a sustainable water use and treatment in chemical industry (and related process industry sectors)" considering technological and non-technological issues.
In the CEN Workshop Agreement "SustainWATER" the results and experiences on how to come to an efficient and sustainable water use and treatment are brought together out of the E4Water case studies to provide a guidance document on this approach The main objective of the E4Water project is to develop, test and validate new integrated approaches, methodologies and process technologies for a more efficient and sustainable use and treatment of water in chemical industry with transfer potential to other sectors.

ISO/TR 15916:2015 provides guidelines for the use of hydrogen in its gaseous and liquid forms as well as its storage in either of these or other forms (hydrides). It identifies the basic safety concerns, hazards and risks, and describes the properties of hydrogen that are relevant to safety. Detailed safety requirements associated with specific hydrogen applications are treated in separate International Standards. "Hydrogen" in this paper means normal hydrogen (1H2), not deuterium (2H2) or tritium (3H2).

IEC 60050-114:2014 gives the general terminology used in electrochemistry. The terminology specific to primary and secondary cells and batteries is given in IEC 60050-482. This terminology is consistent with the terminology developed in the other specialized parts of the IEV. This IEV part is consistent with ISO 80000-9.
It has the status of a horizontal standard in accordance with IEC Guide 108.

ISO 26142:2010 defines the performance requirements and test methods of hydrogen detection apparatus that is designed to measure and monitor hydrogen concentrations in stationary applications. The provisions in ISO 26142:2010 cover the hydrogen detection apparatus used to achieve the single and/or multilevel safety operations, such as nitrogen purging or ventilation and/or system shut-off corresponding to the hydrogen concentration. The requirements applicable to the overall safety system, as well as the installation requirements of such apparatus, are excluded. ISO 26142:2010 sets out only the requirements applicable to a product standard for hydrogen detection apparatus, such as precision, response time, stability, measuring range, selectivity and poisoning. ISO 26142:2010 is intended to be used for certification purposes.

ISO 16110-1:2007 applies to packaged, self-contained or factory matched hydrogen generation systems with a capacity of less than 400 m3/h at 0 °C and 101,325 kPa, herein referred to as hydrogen generators, that convert an input fuel to a hydrogen-rich stream of composition and conditions suitable for the type of device using the hydrogen (e.g. a fuel cell power system or a hydrogen compression, storage and delivery system). It applies to hydrogen generators using one or a combination of the following input fuels: — natural gas and other methane-rich gases derived from renewable (biomass) or fossil fuel sources, e.g. landfill gas, digester gas, coal mine gas; — fuels derived from oil refining, e.g. diesel, gasoline, kerosene, liquefied petroleum gases such as propane and butane; — alcohols, esters, ethers, aldehydes, ketones, Fischer-Tropsch liquids and other suitable hydrogen-rich organic compounds derived from renewable (biomass) or fossil fuel sources, e.g. methanol, ethanol, di-methyl ether, biodiesel; — gaseous mixtures containing hydrogen gas, e.g. synthesis gas, town gas. ISO 16110-1:2007 is applicable to stationary hydrogen generators intended for indoor and outdoor commercial, industrial, light industrial and residential use. It aims to cover all significant hazards, hazardous situations and events relevant to hydrogen generators, with the exception of those associated with environmental compatibility (installation conditions), when they are used as intended and under the conditions foreseen by the manufacturer.
