ČSN EN ISO/ASTM 52903-1 This document describes a method for defining requirements for plastic materials used in extrusion-based additive manufacturing (AM) processes. Materials include unfilled, filled, and reinforced plastic materials suitable for processing into parts. These materials can also contain special additives (e.g. flame retardants, stabilizers, etc.). Processes include all material extrusion-based AM processes. This document is intended for use by manufacturers of materials, feedstocks, plastic parts or any combination of the three using material extrusion-based AM. NOTE - In some cases, material manufacturers can also be feedstock manufacturers. In other cases, a material manufacturer can supply materials (example: pellets) to a feedstock manufacturer (example: converter of pellets into filaments). This document does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health, and environmental practices and determine the applicability of regulatory limitations prior to use.

ČSN EN ISO 11127-3 This document specifies a method for the determination of the apparent density of non-metallic blast-cleaning abrasives. This document is a part of the ISO 11127 series dealing with the sampling and testing of non-metallic abrasives for blast-cleaning. The types of non-metallic abrasive and requirements for each are contained in the ISO 11126 series. The ISO 11126 and ISO 11127 series have been drafted as a coherent set of International Standards on non-metallic blast-cleaning abrasives. Information on all parts of both series is given in Annex A.

ČSN EN ISO 11127-2 This document specifies a method for the determination of the particle size distribution of non-metallic blast-cleaning abrasives by sieving. This document is a part of the ISO 11127 series dealing with the sampling and testing of non-metallic abrasives for blast-cleaning. The types of non-metallic abrasive and requirements for each are contained in the ISO 11126 series. The ISO 11126 and ISO 11127 series have been drafted as a coherent set of International Standards on non-metallic blast-cleaning abrasives. Information on all parts of both series is given in Annex A.

ČSN EN ISO 11127-5 This document specifies a method for the determination of the level of free moisture present in non-metallic blast-cleaning abrasives. It is determined by measuring the mass lost on heating. This document is one of a number of parts of ISO 11127 dealing with the sampling and testing of non-metallic abrasives for blast-cleaning. The types of non-metallic abrasive and requirements on each are contained in the ISO 11126 series. The ISO 11126 series and the ISO 11127 series have been drafted as a coherent set of International Standards on non-metallic blast-cleaning abrasives. Information on all parts of both series is given in Annex A.

ČSN EN ISO 15616-4 This part of ISO 15616 provides minimum requirements for acceptance testing, using practical test methods, for CO2-laser beam machines for high quality welding and cutting in two dimensions (2-D), having a fixed workpiece on the platen and moving optics. This part of ISO 15616 is not applicable to CO2-laser beam machines which use an articulated robot, nor does it apply to work stations, such as a welding positioner, fixed board cutter, etc. This part of ISO 15616 does not cover hazard protection devices, such as those for discharging chips and particles generated during welding and cutting.

ČSN EN 16842-5 This document specifies the requirements and test procedures for 360° visibility of sit on self-propelled industrial variable-reach trucks (herein after referred to as trucks) without a load, with a capacity greater than 10 000 kg in accordance with ISO 5053-1. t is intended be used in conjunction with EN 16842 1. Where specific requirements in this part are modified from the general requirements in EN 16842-1, the requirements of this part are truck specific and to be used for sit-on self-propelled industrial variable-reach trucks with a capacity greater than 10 000 kg. This part of EN 16842 deals with all significant hazards, hazardous situations or hazardous events, relevant to the visibility of the operator for applicable machines when used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer. This document does not deal with rough-terrain variable-reach trucks (see EN 15830).

ČSN EN 4035 This document specifies the characteristics of adjustable rod ends with self-aligning double row ball bearing in corrosion resisting steel with reduced internal radial clearance and threaded shank in titanium alloy, designed to withstand only slow rotations and oscillations under load. They consist of: - a rod end comprising: - circumferential groove to confirm that the assembled rod-end is "in safety" emphasized with the application of red paint; - either seals or shields; - an optional longitudinal groove for locking purpose; - an inner ring with balls. These rod ends are intended for use with flight control rods or rods for aerospace structures. They are intended to be used in the temperature range: -54 °C to 150 °C. However, being lubricated with the following greases: - very high pressure grease, ester type (code A), operational range -73 °C to 121 °C; or - very high pressure grease, synthetic hydrocarbons, general purpose (code B), operational range -54 °C to 177 °C (see EN 2067); their field of application when lubricated with code A grease is limited to 121 °C.
