Metalinės ir kitos neorganinės dangos. Elektrocheminės nikelio, nikelio plius chromo ir vario plius nikelio plius chromo dangos (ISO/DIS 1456:2025)

ISO 1456:2009 specifies requirements for decorative nickel, nickel plus chromium, copper plus nickel and copper plus nickel plus chromium coatings that are applied to iron, steel, zinc alloys, copper and copper alloys, and to aluminium and aluminium alloys, to provide an attractive appearance and enhanced corrosion resistance. Coating designations are specified that differ in thickness and type, and guidance is given on selecting the coating designation appropriate for the service conditions to which the coated product will be exposed. ISO 1456:2009 does not specify the surface condition required by the basis metal prior to the coating process, and is not applicable to coatings on sheet, strip or wire in the non-fabricated form nor to threaded fasteners or coil springs.

Bendrieji pigmentų ir užpildų tyrimo metodai. 24 dalis. Spalvotųjų pigmentų santykinio spalvinimo stiprio ir santykinės baltų pigmentų išsklaidymo gebos nustatymas. Fotometriniai metodai (ISO/DIS 787-24:2025)

The method specified provide an instrumental alternative to those described in ISO 787/16 and ISO 787/17. Equal masses of a coloured material are separately dispersed in the same mass of the same white pigment paste. The reflectivity of each dispersion is measured photometrically. From the corresponding values of K/S the relative tinting strength is given. For measurement of the relative scattering power equal masses of a white test material and an agreed reference pigment are separately dispersed in the same mass of the same black pigment paste. The reflectivity of each dispersion is measured photometrically at 550 nm. From the corresponding values of K/S the relative scattering power is given.

Bendrieji pigmentų ir užpildų tyrimo metodai. 5 dalis. Naftos absorbcijos vertės nustatymas (ISO/DIS 787-5:2025)

The oil absorption value is required to be compared with the value determined at the same time on an agreed sample of the product. The principle of the method is based on addition of linseed oil from a burette to the test portion. After each addition, rub the oil into the product until conglomerates are formed. Cease the addition of oil when a paste of smooth consistency has been formed. It should just spread without cracking or crumbling. Read the burette and note the quantity of oil used. The result is expressed in millilitres of oil per 100 g of product or in grams of oil per 100 g of product. - Cancels and replaces Part 5 of ISO/R 787-1968.

Kranai. Lengvųjų kranų sistemos

This document applies to: — light crane systems, either suspended or free-standing systems, where the rated capacity of any single hoist mechanism is 4 t or less; — pillar- and wall-mounted jib cranes, without an operator's cabin, whose rated capacity is 10 t or less and whose overturning load moment is 500 kNm or less. NOTE 1 For illustration of crane types, see Annex C. This document is not applicable to cranes covered by another product specific crane standard, e.g. EN 15011:2020 or EN 14985:2012, see Annex E. This document is applicable to cranes and crane systems, whose structures are made of steel or aluminium, excluding aluminium structures containing welded joints. This document gives requirements for all significant hazards, hazardous situations and events relevant to cranes, when used as intended, foreseeable misuse and under foreseen conditions (see Annex A). NOTE 2 Automated operation can be subject to additional requirements. Guidance is given in Annex F. The specific hazards due to potentially explosive atmospheres, ionizing radiation, operation in electro-magnetic fields beyond the range of EN IEC 61000-6-2:2019 and operation in pharmacy or food industry are not covered by this document. This document does not cover hazards related to the lifting of persons. This document is not applicable to cranes manufactured before the date of its publication.

Maisto produktai. Visuminio azoto kiekio nustatymas pagal Diuma (Dumas) principą ir žalio baltymo kiekio skaičiavimas. 1 dalis. Aliejingosios sėklos ir pašarai (ISO/DIS 16634-1:2025)

ISO 16634-1:2008 specifies a method for the determination of the total nitrogen content and the calculation of crude protein content of oilseeds and animal feeding stuffs. This method, like the Kjeldahl method, does not distinguish between protein nitrogen and non-protein nitrogen. For the calculation of protein content, various conversion factors are used. This method is not applicable to milk and milk products.

Žemės ūkio mašinos. Sauga. Kompaktinės savaeigės mašinos su keičiamais įtaisais

This document specifies the safety requirements and their verification for the design and construction of compact carriers used in agriculture. It is intended to be used together with EN ISO 4254-1:20152. When provisions of this document are different from those which are stated in EN ISO 4254-1:2015, the provisions of this document take precedence over the provisions of EN ISO 4254-1:2015 for machines that have been designed and built according to the provisions of this document. This document deals with the significant hazards, hazardous situations and events relevant to compact carriers, when they are used as intended and under the conditions foreseen by the manufacturer but also taking into account any reasonably foreseeable misuse thereof (see Annex A). In addition, this document specifies the type of information on safe working practices that is provided by the manufacturer. This document does not deal with hazards related to: - pesticide application; - lifting operations; - lifting of persons. While this document does not deal with the design and construction of interchangeable equipment, requirements in this document also address hazards which can occur from the combination of compact carriers with interchangeable equipment as per multiple uses intended by the manufacturer of the compact carrier. Compact carriers when provided with cab and provisions for fitting a cab are not dealt with this document. Compact carriers intended for a seated operator are not dealt with this document. Agricultural tractors and machines falling within the scope of standards EN 474 are excluded by this document. This document is not applicable to machines manufactured before the date of its publication.
