The technological base of any enterprise is the key to the structuring of the production process. In order for new technologies not to put an established system in a difficult position, it is necessary to be aware of new standards in the field of any business. When it comes to chemical production, engineering solutions and the use of various substances, it is necessary to take into account all the rules and regulations that are recommended to minimize negative consequences. Today we will introduce you to the standards, the scope of which is not very extensive. But if the business comes into contact with the areas described in these documents, then we recommend that you follow the norms specified in international standards without fail.
Shell boilers - Part 5: Inspection during construction, documentation and marking of pressure parts of the boiler
The use of boilers is common both in production processes and in special cases. To prevent possible risks during use, installation and operation, it is necessary to adhere to the rules and regulations specified in the relevant standards, such asSIST EN 12953-5:2020. This document specifies requirements for the inspection during construction, documentation and marking of shell boilers as defined in EN 12953-1. For other components, such as water tube walls, reference will be made to EN 12952 series. If you look at this standard in more detail, you will notice a wide variation in the scope of its application. That is why, in order to make sure that this particular document is necessary for the development of your company, contact the iTeh team to clarify all the questions that arise.
Gas cylinders - Flexible hoses assemblies - Specification and testing
Another important standard in the installation and use of technical equipment is SIST EN ISO 16964:2020. This document provides specification and testing requirements for high pressure flexible hose assemblies intended to be connected to gas cylinders, bundles of cylinders or trailers (battery vehicles), and MEGCs for use when filling and emptying gas at production sites and also for customer use. This document applies to flexible hose assemblies with rated pressures up to 1 000 bar for use in the temperature range of −40 °C to +65 °C. This document is not applicable to: — rubber and plastics flexible hose assemblies for welding, cutting and related processes up to 45 MPa (450 bar) for customer use (see ISO 14113); — high pressure flexible hose assemblies for use with medical gas systems for customer use (see ISO 21969); — low pressure hose assemblies for use with medical gases for customer use (see ISO 5359); — rubber and thermoplastic low pressure hose assemblies for welding, cutting and related processes for customer use (see ISO 3821 or ISO 12170); — flexible hose assemblies for cryogenic applications (see ISO 21012); — flexible hose assemblies for liquid petroleum gas (LPG). It should be noted that this document is quite narrow. specialized, which is why we recommend that you familiarize yourself with its characteristics in more detail on our website.
Gaseous hydrogen - Cylinders and tubes for stationary storage
In continuation of the standards describing the technological equipment of a particular production, as well as the rules for the use of certain substances, I would like to emphasize once again the strict need for basic standards for your enterprise and its structural step-by-step development without any problems. SIST EN 17533:2020 specifies the requirements for design, manufacture and testing of cylinders, tubes, and other pressure vessels of steel, stainless steel, aluminium alloys or of non-metallic construction material intended for the stationary storage of gaseous hydrogen of up to a maximum water capacity of 10 000 l and a maximum allowable working pressure not exceeding 110 MPa, of seamless metallic construction (Type 1) or of composite construction (Types 2, 3 and 4) without any non-seamless load sharing metallic components, hereafter referred to as pressure vessels. For Existing design already qualified for other applications (e.g. transportable applications) follow the requirements of Annex E. This International Standard is not intended as a specification for pressure vessels used for solid, liquid hydrogen or hybrid cryogenic-high pressure hydrogen storage applications. Since different terminology and definitions in the texts can be perceived from different points of view, we recommend that you contact us for more detailed information on this standard.
Non-destructive testing of welds - Ultrasonic testing - Use of time-of-flight diffraction technique (TOFD)
Automated production requires a certain level of awareness of the necessary regulatory legal documents that are associated with production specifics. Thus, at the international level, every day more and more standards arise that regulate various technical areas of production, one of them will be discussed below. This document specifies the application of the time-of-flight diffraction (TOFD) technique to the semi- or fully automated ultrasonic testing of fusion-welded joints in metallic materials of minimum thickness 6 mm. It applies to full penetration welded joints of simple geometry in plates, pipes, and vessels, where both the weld and the parent material are low-alloyed carbon steel. Where specified and appropriate, TOFD can also be used on other types of materials that exhibit low ultrasonic attenuation (especially that due to scatter). Where material-dependent ultrasonic parameters are specified in this document, they are based on steels having a sound velocity of (5 920 ± 50) m/s for longitudinal waves and (3 255 ± 30) m/s for transverse waves. It is necessary to take this fact into account when testing materials with a different velocity. This document makes reference to ISO 16828 and provides guidance on the specific capabilities and limitations of TOFD for the detection, location, sizing and characterization of discontinuities in fusion-welded joints. TOFD can be used as a stand-alone method or in combination with other non-destructive testing (NDT) methods or techniques, for manufacturing inspection, and for in-service inspection. This document specifies four testing levels (A, B, C, D) in accordance with ISO 17635 and corresponding to an increasing level of testing reliability. Guidance on the selection of testing levels is provided. This document permits assessment of TOFD indications for acceptance purposes. This assessment is based on the evaluation of transmitted, reflected and diffracted ultrasonic signals within a generated TOFD image. This document does not include acceptance levels for discontinuities. Precisely for the reason that in every even generalized standard there are certain amendments, before purchasing a specific document, we recommend that you study in more detail its compliance with the specifics of your business. You can easily do this by going to the iTeh website.
Chemical disinfectants and antiseptics - Methods of airborne room disinfection by automated process - Determination of bactericidal, mycobactericidal, sporicidal, fungicidal, yeasticidal, virucidal and phagocidal activities
Much has been said about the popularization of the development of the medical sector in our time. Nevertheless, the question remains relevant to this day, which is why the number of emerging standards for regulating this industry is increasing every day. Today we will introduce you to the standard that describes the method of disinfection and the use of antiseptic agents. The method described herein is designed to determine the disinfectant activity of processes used in hospital, medical, pharmaceutical and cosmetics, veterinary, industrial and food processing areas. The product trialled is designed to be diffused as gaseous molecules or solid or liquid-form dispersants. NOTE Concerning automatic disinfectant processes: the limits to use, especially in terms of ability to diffuse throughout the room (min and max effective volumes), shall be specified and stated in the test report; certain automatic disinfection processes are only suitable for use in large-volume spaces well in excess of 150 m3. Under these conditions, the systems cannot be tested in indoor spaces less than 150 m3 due to the high power of the jet spray; "additional experimental conditions" (see 22.214.171.124.f) should therefore be used and the tests should only be performed in test rooms with volumes different to the obligatory conditions. It should be noted that this standard can be useful in any area of business, especially in the context of a global pandemic and the fight against it, which is why the presence of this standard can become a significant competitive advantage for your company today.
Setting standards for your business can be much easier than seems from the first sight.
As you can see, each standard is very specific and any area of activity that comes into contact with the chemicals described in the documents, technical installations, must be strictly standardized to avoid possible negative consequences. Moreover, if some standards can be widely used both by companies and in everyday life, then the above documents are narrow-profile. Choosing the right standard for your business will not only create a solid regulatory and technological framework, but will also significantly increase the level of your company's presence in the international market. We have listed only a few of the standards used in production. In order to most accurately select the document you need, go to our website https://standards.iteh.ai and contact us to clarify your questions. The iTeh team will help you choose exactly those standards that will significantly improve the quality of your business.
