1 Scope This European Standard specifies the requirements for factory made products for external thermal insulation composite systems (ETICS) based on expanded polystyrene, delivered as a kit, and used as thermal insulation for buildings. The standard describes product characteristics and includes procedures for testing, marking and labelling. ETICS are applied to external surfaces of new or existing walls and/or soffits […]

1 Scope 1.1 This document applies to splitting, skiving, edge trimming, strip cutting, cementing and cement drying machines used in the manufacture of footwear, leather and imitation leather goods and other related components. 1.2 This document does not apply to: trimming machines with rotary milling tool for the purpose of trimming edges of material, see EN 930; splitting and band […]

5.3 Dimensions 5.3.1 Principal dimensions The length of the beam shall conform to the manufacturers declared dimension within a tolerance of 10 mm. The beam depth, H , shall conform to the data in Tables 1 and 2 within a limit deviation of ± 1 % or ± 2 mm,whichever is the smaller. The flange width, b , shall conform […]

4 Materials and heat treatment 4.1 General 4.1.1 Materials supplied for shells and end pressing shall conform to EN 10120, or EN 10028-1 and EN 10028-3,or EN 10028-1 and EN 10028-5. 4.1.2 Materials supplied for bungs shall conform to EN 10083-1 + A1. 4.1.3 Grades of steel used for the manufacture shall be compatible with the intended gas service (e.g. […]

1 Scope This European Standard specifies a reference method for the measurement of low dust concentration in ducted 3 standard conditions. This method has been validated with gaseous streams in the concentrations below 50 mg/m 3 on an average half hour sampling time. special emphasis around 5 mg/m This European Standard is primarily developed and validated for gaseous streams emitted […]

1 Scope This European Standard provides an accepted “terminology” for switch and crossing work. With the assistance of diagrams, the various components are given definitions, and these specific names are regarded as obligatory. The definitions cover the constituent parts and design geometry of switch and crossing work, and include the movement of switches. Additional terminology of a more specific nature […]

4 Classification of leaks 4.1 Permeation leak This type of leak is normally made with a tracer gas reservoir. It has the best long-term stability but an appreciable temperature coefficient (approximately 3,5 %/K). Typical leakage rates are in the range from 10 – 10 Pa·m 3 /s to 10 -4 Pa·m 3 /s. 4.2 Conductance leaks 4.2.1 Capillary leak This […]

4.2 Unsaturated polyester resins Unsaturated polyester resins (UP) are thermosetting resins consisting of polyester molecules, dissolved in a reac- tive monomer (e.g. styrene) capable of copolymerisation with the polyester. The polyester molecules are built from polyhydric alcohols (polyols) and polyvalent carboxylic acids (e.g. ethylene dicarboxylic acids like fumaric acid and/or maleic acid) and cyclic unsaturated hydrocarbons (e.g. dicyclopentadiene) by a […]

1 Scope This European Standard describes a method for determining the horizontal drainability of a road surface as an indicator of relatively low surface texture using the outflow meter as a stationary device. The method provides a measure of the drainability in the road/tyre contact area for use on all smooth non porous road surfaces (less than 0,4 mm mean […]

5 Safety requirements and/or protective measures Machinery shall comply with the safety requirements and/or protective measures of this clause. In addition, the machine shall be designed according to the principles of EN 292 for hazards relevant but not significant which are not dealt with by this document (e.g. sharp edges). NOTE For application of a B-level standard such as EN […]
