ČSN EN ISO 8362-2 This document specifies the shape, dimensions, material, performance requirements and labelling of closures for injection vials covered by ISO 8362-1 and ISO 8362-4. The dimensional requirements are not applicable to barrier-coated closures. Closures specified in this document are intended for single use only. NOTE - The potency, purity, stability and safety of a medicinal product during its manufacture and storage can strongly be affected by the nature and performance of the primary packaging.

ČSN EN ISO 17892-1 (72 1007) Tato mezinárodní norma popisuje metodu stanovení vlhkosti zemin. Tato mezinárodní norma je použitelná pro laboratorní stanovení obsahu vody (známé také jako vlhkost) ve zkušebním vzorku zeminy vysoušením v sušárně v rámci geotechnických průzkumů. Vlhkost je požadována jako vodítko pro klasifikaci přírodních zemin a jako kontrolní kritérium ve zhutněných zeminách a stanovuje se na vzorcích používaných pro většinu terénních a laboratorních zkoušek. Základní referenční postup stanovování vlhkosti, běžný v laboratorní praxi, je sušení v sušárně. Vhodný postup pro stanovení vlhkosti zeminy je určit hmotnost vody odstraněné při vysušení vlhkého zkušebního vzorku do ustálené hmotnosti v regulovatelné sušárně při stanovené teplotě. Předpokládá se, že úbytek hmotnosti je způsoben volnou vodou a vztahuje se ke zbývající suché hmotnosti pevných částic. POZNÁMKA - Tento dokument splňuje požadavky na stanovení vlhkosti v zeminách pro geotechnický průzkum a zkoušení v souladu s EN 1997-1 a EN 1997-2.

ČSN EN ISO 22074-2 This document specifies the laboratory test procedure to determine: a) the maximum longitudinal force that can be applied to a rail, secured to a sleeper, bearer or element of ballastless track by a rail fastening assembly, without non-elastic displacement of the rail occurring, or the longitudinal stiffness at a specified longitudinal displacement of a specimen of embedded rail with an adhesive fastening system, and for any type of fastening; b) the shear displacement and slip data required for track-bridge interaction calculations.

ČSN EN ISO 22074-1 This document specifies the terms and definitions used in the ISO 22074 series of standards related to rail fastening systems. NOTE In this document, there are some entries where more than one term is listed in the header (e.g. sleeper, tie, cross tie in 3.2.3). In such cases, the first term is the preferred term, generally used in the ISO 22074 series of standards. The other terms are also in common use in the railway industry and are considered to be synonymous (admitted terms).

ČSN EN ISO 22074-3 This document specifies a test procedure to confirm that the force necessary to pull the anchorage of a rail fastening assembly out of the sleeper or other supporting element is greater than a prescribed value (i.e. it is a "proof load" test). This test is for components of the fastening system which are: a) cast into concrete during the manufacture of sleepers or other supporting elements; b) glued into the cast or drilled holes in concrete; or c) screwed or otherwise attached to wood, polymeric composite or steel sleepers or other supporting elements. This test is not applicable to embedded rails.

Obsah

ČSN EN ISO 22074-6 This document specifies a laboratory test procedure for finding the effect of exposure to severe environmental conditions on the fastening system. This test procedure applies to a complete fastening assembly including embedded rail with mechanical fastenings. It is not applicable to embedded rail systems relying on adhesive components to secure the rail.

Obsah

ČSN EN ISO 22074-7 This document specifies the laboratory test procedure for determining the clamping force exerted by the fastening system on the foot of the rail by measuring the force to separate the rail foot from its immediate support. When required, the procedure is also used to determine the uplift stiffness of the fastening system. It is applicable to systems with and without baseplates on all types of sleepers, bearers or elements of ballastless track. The test does not determine the security of the fastening components fixed into the sleeper or other fastening system support. This test procedure applies to a complete fastening assembly. It is not applicable to fastening systems for embedded rail or other fastening systems which do not act on the foot of the rail.

Obsah

ČSN EN ISO 22074-5 This document specifies a laboratory test procedure for determining the electrical resistance, in wet conditions, between the running rails provided by a fastening system fitted to a steel or concrete sleeper, bearer or element of ballastless track. It is also applicable to embedded rail. This test procedure applies to a complete fastening assembly. It is relevant to signalling currents, not to traction currents. A reference procedure and an alternative procedure are included.

ČSN EN ISO 28862 This document specifies performance requirements and methods of test for non-reclosable packaging that has been designated child-resistant and which is intended to contain non-pharmaceutical products. This document is intended for type approval only (see 2.5) and is not intended for quality assurance purposes. This document applies to non-reclosable packages of the single-use type consisting of one or more individual units. Non-reclosable packages for pharmaceutical products are excluded from the scope of this document. These are the subject of a separate standard, ISO 14375, Child-resistant non-reclosable packaging for pharmaceutical products - Requirements and testing.

ČSN EN ISO 7965-1 This document specifies a method of vertical impact testing on a filled paper sack by dropping. It is performed either as a single test to investigate the effects of vertical impact or as part of a sequence of tests designed to measure the ability of a sack to withstand a distribution system that includes a vertical impact hazard. This document specifies the testing procedure and how the results of tests are presented. It is based on ISO 2248 but is specifically related to paper sacks.
