ČSN EN ISO 20182 Tento dokument určuje postup přípravy zkušebních panelů ze žárovzdorných materiálů torkretováním pomocí pistole s pneumatickým směšováním v trysce při teplotě okolí. Zkušební tělesa pro stanovení vlastností na torkretovaných výrobcích se připravují buď za "standardních podmínek" (jak se požaduje při zjišťování kvality nebo při vývoji výrobku), nebo "za provozních podmínek". V případě "provozních podmínek" je účelem zkoušení stanovení vlastností odpovídajících dané instalaci nebo danému souboru podmínek instalace. V tomto případě je možné panel připravit v průběhu instalace na místě. Podmínky jako okolní teplota, nadmořská výška, tlak vzduchu a podmínky vytvrzování (teplota, orientace panelu) použité při přípravě panelu jsou v tomto případě nejblíže příslušným podmínkám, které byly při instalaci na místě. Je také možné simulovat určité "provozní podmínky" torkretováním panelů mimo staveniště, například v laboratorním prostředí. To je podle tohoto dokumentu možné na základě dohody mezi zúčastněnými stranami. Tento dokument se nevztahuje na torkretování plastických směsí a směsí obsahujících kameniva náchylná k hydrataci. Tento dokument se nevztahuje na shotkretovací směsi, kterými se zabývá ISO 18886.

ČSN EN ISO 8840 Tento dokument určuje tři metody stanovení objemové hmotnosti zrněných žárovzdorných materiálů (hustota zrn) o velikosti zrn větší než 2 mm: - Metoda 1: rtuťová vakuová metoda; - Metoda 2: metoda přerušené nasákavosti vody; - Metoda 3: vakuová metoda s možností odstředění podle ISO 5017. - Metoda 1 je zamýšlena jako referenční metoda. Pro stanovení objemu vzorku, pro výběr a přípravu vzorku, pro výpočet objemové hmotnosti a pro uvedení v protokolu o zkoušce se použije vždy stejná metoda.

ČSN P CEN/TS 17217 This document covers physical properties and manufacturing requirements for envelopes having an address window and the flap on the front side once the flap has been sealed, hereafter the flap side. It covers the main design features of the reverse envelope, notably of the flap and address window, and the materials used for the manufacturing thereof. It applies to reverse envelopes with advertising or communication printed on the plain side, eventually on its entire surface. This document covers empty envelopes, but also finished mailpieces that have been properly inserted, addressed and franked (reverse mailpieces) and are submitted to Postal Operators. In particular, reverse mailpieces will be compliant with relevant Postal standards applicable in the member states. By extension, these requirements also apply to non-window envelopes used for reverse mailpieces and having the address printed on the flap side. This document does not apply to: - envelopes with a large window on the plain side (opposite to the flap) as these are already common and widely accepted, - paper requirements to ensure print quality (except for the postage mark and address) and notably colour rendering.

ČSN EN 17984-6 This document specifies requirements and recommendations for the accessibility of public and private spaces and universal access for assistance dog teams in an active status. The accessibility requirements and recommendations for assistance dog teams in this document are applicable across the full spectrum of the built environment both indoor and outdoor (e.g. social service, medical and educational facilities, public institutions, cultural venues, sporting venues, hotel accommodation, public transport, parks, nature reserves). The purpose of this document is to improve the accessibility for assistance dog teams ensuring their rights under the United Nations Convention on the Rights of Persons with Disabilities, so that they have the same opportunities as all citizens and can participate independently in all areas of life. This document provides: - specific requirements of assistance dog teams to support accessibility and to achieve universal access; - responsibilities of assistance dog teams to enhance the public acceptance of assistance dogs; - guidance for specific services and areas to be accessed; - guidance for the implementation of accessibility measures at public and private bodies responsible for the built environment including transport and travel systems. This document includes all private spaces where the public are generally admitted, or where the public can be accommodated (e.g. office buildings, waiting rooms, common areas of apartment buildings). This document can be applied to improve accessibility of assistance dog teams in the workplace. This document can be applied to assistance dogs in training and puppies preparing for an assistance dog role.
