Electronic devices have invariably played a vital role in the way of life of every human being. At the beginning of the post-industrial event, the problem of automation, which was associated with the innovative study development in companies of different sizes, began to be subject to transparent regulation and transparency. Legal framework conditions that gradually create restrictions and harbor development potential when expanding the business. The introduction and use of devices is now an integral part of both small and medium-sized companies as well as large company structures requires constant further development and adaptation to new market requirements, therefore it is essential to keep pace with the latest norms and requirements, which are mainly for the standard of products and services produced are collected. the international level for the various industries and the instruments used in them are international standards.
Gel Permeation Chromatography (GPC) Part 1: Tetrahydrofuran (THF) as an eluent (ISO 138851: 2020)
EN ISO 22553-1: 2020
Industrial processes and the introduction of equipment into their structures always require a step-by-step guide to recommendations. Interaction between countries or the introduction of imported devices, the question of a high-quality regulatory framework is on the agenda in case this situation occurs with electronic devices that can be used in different industries, international documents such as EN ISO 22553-1: 2020 come to the rescue.
This document defines terms for electrodeposition paints.
Applies to electrodeposition paints for the automotive industry and other general industrial applications, e.g. Eg cooling units, consumer goods, radiators, aerospace, agriculture.
This international document can be used in various branches that are not related to one another in their specialization. However, the specificity of this document is that it focuses on the regulation of standards and regulations related to the use and implementation of certain devices, a clear understanding of the scope of its regulatory specificities.
Gel Permeation Chromatography (GPC) Part 2: N, NDimenthylacetamide (DMAC) as eluent (ISO 138852: 2020)
EN ISO 13885-2: 2021
Chemical and physical processes are an essential part of establishing a system interaction between systems as a function of the electrical properties. In addition, it should be noted that the complexity of the approach to solving the regulatory framework in relation to these issues is increasing daily and therefore adequate documentation is required.This is where international standards such as EN ISO 13885-2: 2021 come to the rescue.
This document specifies the determination of the molar mass distribution and the mean molar mass values Mn (number average) and Mw (weight average) of DMAC-soluble polymers (N, N-dimethylacetamide) by means of gel permeation chromatography (GPC). .
NOTE Also known as size exclusion chromatography (SEC).
Although the chromatograms obtained show good repeatability, this method cannot be used with certain polymer types due to specific interactions (eg adsorption) within the sample / eluent / column system.
The conditions specified in this document do not apply to the GPC analysis of polymer samples with Mw values greater than 106 g / mol and / or polymers with elution limits outside the calibration range (see 7.6 and Appendix C).
This document does not contain any correction methods (eg to remove peak broadening). If absolute values of the molar mass are required, an absolute method can be used (e.g. membrane osmometry for Mn or light scattering for Mw).
The technological properties listed in this document enable you to check your requirements with the legal framework of your organization as well as with the requirements for the operation of the devices used in your company, which is why the availability of international standards reduces the possible financial and physical risks in your company or Your organization.
Gel Permeation Chromatography (GPC) Part 3: Water as an eluent (ISO 138853: 2020)
EN ISO 13885-3: 2020
Taking into account the structure of an electrical equipment system and large-scale production, there is a need for documentation that regulates absolutely all stages. We have already mentioned the interplay of physical and chemical elements when setting up a company structure or when setting up production facilities. of water in systems that interact with electricity, one of the most relevant legal acts today is the international standard EN ISO 138853: 2020.
This document specifies the determination of the molar mass distribution and the mean molar mass values Mn (number average). and Mw (weight average) of polymers soluble in water by gel permeation chromatography (GPC).
NOTE Also known as size exclusion chromatography (SEC).
This procedure is applicable to neutral polymers and polyanions (e.g. polycarboxylates, polysaccharides, fully hydrolyzed polyvinyl alcohols and high molecular weight polyethylene oxides). It does not apply to polycations [p. For example polyvinylpyrrolidone, polyvinylpyridine, salts of poly , chitosan].
Despite the good solubility in the mobile phase and despite the good reproducibility of the chromatograms obtained, it is possible that this method may not work with certain polymer types due to specific interactions (e.g. adsorption) within the sample system.
The conditions specified in this document do not apply to the GPC analysis of polymer samples with Mw values greater than 106 g / mol and / or polymers with elution limits outside the calibration range (see 7.6 and Appendix C).
This document does not contain any correction methods (eg for removing peak broadening). If absolute values of the molar mass are required, an absolute method can be used (e.g. membrane osmometry for Mn or light scattering for Mw).
Chemical elements are the basis for the formation of every system, therefore the influence of the molecular level in the construction of global mechanical and electronic systems should not be underestimated.The implementation of international standardization at every stage of the activities carried out will increase the rate of escalation and the number of possible vectors of corporate movement.
Paints and Varnishes Electrocoats Part 8: Electrical Charge Density (ISO 225538: 2020)
EN ISO 22553-8: 2021
Despite the fact that electrical devices are primarily subject to regulation from a technological point of view, international standards institutes do not let yourself be overlooked Construction of equipment and related parts. For such rare but significant cases, international documents such as EN ISO 225538: 2021 are created.
This document specifies a method for determining the electrical charge density of an electrodeposition coating (E-layer) for the automotive industry and others. general industrial applications, e.g. cooling units, consumer goods, radiators, aerospace, agriculture.
The coating of elements of electrical equipment not only influences the external properties, but above all safety aspects, since the decorative elements (paint, rubber, coatings) have a different chemical composition, therefore each element changes its properties and status to a different extent when heated . So if you are concerned about safety issues, this International Standard is a must.
Government Assistance Needs
As mentioned above, each International Standard contains a number of well-defined indicators that affect the implementation and operation of the equipment. In addition, individual parts of the same document can be used in completely opposite ways in related areas.Quality is a key element in promoting a company or organization, making it possible to plan the stages of entry into more global and larger markets and to minimize the possible risks of non-compliance with legal requirements between states. a major impact on the size of the European Union markets. If your company or organization operates in an area outside the EU and therefore requires more global standards, you can familiarize yourself with the list of all documents available on our website and purchase the exact document that is relevant to your region of commercial activities.
