prEN 13411-9 - Terminations for steel wire ropes - Safety - Part 9: Solid thimbles
Ämnesområden: Klammer, märlor och övriga fästelement; Lyfttillbehör och lyftredskap; Övriga järn och stål produkter
Kommittébeteckning: SIS/TK 222 (Lyftredskap)
Svarsdatum: den 11 feb 2020
This document specifies the minimum requirements for solid thimbles made of steel or cast iron for terminations of stranded steel wire ropes. This document is applicable to ferrule-secured terminations with solid thimbles in combination with ferrules according to EN 13411-3, that have an efficiency factor KT of at least 0,9, and to spliced terminations with solid thimbles according to EN 13411-2, that have an efficiency factor KT of at least 0,8, which are used as accessories for steel wire ropes, such as slings or wire rope assemblies, having a lifting, lowering or load-bearing effect in hoisting equipment. Examples of designs of solid thimbles are given in informative Annex B and C. Round thimbles are not subject to this document. This document is applicable to ferrule-secured terminations that are manufactured after the date of publication of this document. Hazards that are dealt with in this document are listed in Clause 4.
ISO/DIS 14404-4 - Calculation method of carbon dioxide emission intensity from iron and steel production - Part 4: Guidance for using ISO 14404 family
Ämnesområden: Nedsmutsning. Regler och skydd; Järn och stål: allmänt
Kommittébeteckning: SIS/TK 120 (Allmänna leveransbestämmelser för metall)
Svarsdatum: den 12 feb 2020
ISO 14404 part 4 provides the guidance for calculating the CO2 intensity at steel plants with all types of process routes, by defining the boundary, CO2 emission factors and the intermediate products for which upstream emissions are considered for all types of process routes. In particular, ISO 14404 part 4 provides the guidance to apply ISO 14404 family to following types of steel plants. ISO 14404 part 4 also includes Universal Calculation Sheet, which covers all relevant emission sources from ISO 14404-1, 2, 3, to assist the calculation of CO2 emissions.
i. Steel plants with different process routes from ISO 14404-1, 2, 3 (7.2.1)
ii. Steel plants with more than one process route (7.2.2)
iii. Steel plants purchasing pig iron from the outside (7.2.3)
iv. Steel plants and rerollers purchasing part or all of crude steel from outside (7.2.4)
Moreover, ISO 14404 part 4 provides additional guidance to the entire ISO 14404 family for the following topics.
a) Evaluation of exported slags
b) Evaluation of by-product gas
c) Evaluation of stock
d) Selection of calorific values and emission factors for electricity and fuel
Conversion to energy consumption and to consumption efficiency can be obtained using Annex A.
While the use of the calculation result is outside Scope of this standard, appropriate applications and inappropriate application are recommended in Annex B.
prEN 10373 - Determination of the physical and mechanical properties of steels using models
Ämnesområden: Verktygsstål; Järn och stålprodukter: allmänt
Svarsdatum: den 19 feb 2020
This document specifies the method for the verification of models for the determination of the property data of steels and the validation of the modelling process. It is applicable where modelling of mechanical or physical properties is used to substitute conventional testing for specific inspection. Models can be based on statistical data, thermo-physical data or indirect measurement (e.g. measurement of magnetic or ultrasonic data), or a combination of these methods.
This document applies only for providing the properties of rolled and/or heat-treated products such as plates, sheets, strip, sections and bars.
This document is used to demonstrate the ability of the model to supply property data which is equivalent to data, measured by conventional testing.
Any self-learning system is excluded from the scope.
NOTE A self-learning model is a model which changes its internal parameters by itself.
ISO/DIS 15177 - Steel sheet, hot-rolled twin-roll cast, of commercial quality
Svarsdatum: den 3 mar 2020
This document specifies the requirements for hot-rolled twin-roll cast steel sheet of commercial quality.
The product is intended for many applications where the presence of oxide or scale or normal surface imperfections disclosed after removal of oxide or scale, are not objectionable. It is not suitable for applications where the surface is of prime importance.
NOTE This document does not cover steel sheet that is to be subjected to subsequent rolling.
ISO/DIS 28080 - Hardmetals - Abrasion tests for hardmetals
Ämnesområden: Provtagning för mekanisk provning; Pulvermetallurgi
Kommittébeteckning: SIS/TK 133 (Pulvermetallurgi)
Svarsdatum: den 10 mar 2020
This International Standard specifies a generic test method to determine the abrasion wear characteristics of hardmetals.
The procedure complements the ASTM G65 method for dry sand/rubber wheel abrasion, the ASTM B611 method for determining the high stress abrasion of hard materials, and the ASTM G105 method for conducting wet sand/rubber wheel abrasion tests.
The test is appropriate for use in situations where test laboratories have a need to simulate abrasive damage. The procedure includes information which enables the test to be used in a variety of different conditions:
a) with counterface wheels of different stiffness (for example steel and rubber);
b) wet and dry;
c) different abrasive sizes;
d) different chemical environments.
ISO/DIS 8407 - Corrosion of metals and alloys - Removal of corrosion products from corrosion test specimens
Ämnesområden: Korrosion
Svarsdatum: den 28 mar 2020
This document specifies procedures for the removal of corrosion products formed on metal and alloy corrosion test specimens during their exposure in corrosive environments. For the purpose of this document, the term "metals" refers to pure metals and alloys.
The specified procedures are designed to remove all corrosion products without significant removal of base metal. This allows an accurate determination of the mass loss of the metal, which occurred during exposure to the corrosive environment.
These procedures may, in some cases, also be applied to metal coatings. However, possible effects from the substrate must be considered.
NOTE If a significant portion of the substrate is visible after the pickling procedure is completed, the results will be unreliable.
