ČSN EN ISO 6427 This document specifies methods for the determination of components in plastics that can be extracted by hot organic liquids near their boiling points. It also specifies a special extraction method called cold-extraction. The extractable components can be monomers, oligomers, polymers, plasticizers, stabilizers, etc. The kind and percentage of extractable matter influence the properties of plastics. This document does not apply to plastics that come into contact with food or drinking water, because special regulations for those plastics are established in many countries. The methods of this document are not intended to be used for migration tests. If this document is used to test plastics other than those mentioned in Table 1, the operating conditions are intended to be agreed upon by the interested parties.

ČSN EN ISO 75-3 This document specifies a method used for the determination of the temperature of deflection under load of specified plastics (including fibre-reinforced plastics in which the fibre length is, prior to processing, greater than 7,5 mm) under defined conditions. A number of different test conditions are defined, depending on the anticipated specimen dimensions. For additional information, see ISO 75-1:2020, Clause 1.

ČSN EN ISO 877-1 This document provides information and general guidance on the selection and use of the methods of exposure to solar radiation described in detail in subsequent parts of the ISO 877 series. These methods of exposure to solar radiation are applicable to plastics materials of all kinds as well as to products and portions of products. It also specifies methods for determining radiant exposure. It does not include direct weathering using black-box test fixtures, which simulate higher end-use temperatures in some applications. NOTE - ASTM G7[1] and ASTM D4141[2] describe black-box exposure tests.

ČSN EN 18064-3 This document provides characteristics and typical values for polypropylene (PP) recyclates intended for groups of defined applications (the product families). The characteristics and typical values for the different product families are derived from the performance requirements of the products belonging to that family, including requirements for product manufacturing processes where applicable. This document applies to plastic recyclates intended to be used for the manufacturing of (intermediate) products. This document is intended to be used in conjunction with part 1 of this standard series, which describes the designation system for plastic recyclates. The designation system allows comparison between recycled and virgin material at the level of the polymer's defined designatory properties. NOTE 1 - Examples of designations of plastic recyclates are given in Annex A. NOTE 2 - The selection of properties for a product family is based on EN ISO 10350-1, extended with specific properties related to plastic recyclates.

ČSN EN 13207 This document specifies the requirements related to dimensional, mechanical, and optical characteristics of thermoplastic films and tubes used during the manufacture of silage and designed to last at least one year for protecting fodder. It specifies a classification for the durability of silage films and the test methods referred to in this document. This document is applicable to transparent, black, white or coloured (e.g. black/white) thermoplastic silage films based on polyethylene, ethylene copolymer, EVOH and polyamide. These films are intended for covering bunker silos, silage tubes or silage clamps for preserving forage. They protect the forage and preserve it from rain and air. These films are not intended to cover bales piles (e.g. straw bales and hay bales). This document does not apply to silage films obtained by sealing two or more films in machine direction. This document also provides guideline for installation, use and removal conditions of silage films. It also provides guideline for the conventional useful lifetime, as well as rules that allow evaluating the remaining use potential in the event of a failure before the normal end-of-use date.

ČSN ISO 9854-1 Tento dokument specifikuje dvě obecné metody zkoušení metodu A a metodu B, které se používají pro stanovení rázové houževnatosti zkušebních těles bez vrubu i s vrubem řezaných z trubek z termoplastů, které jsou určeny pro rozvod kapalin. - Metoda A: metoda pro zkušební tělesa bez vrubu řezaná z trubek z termoplastů, které jsou určeny pro rozvod kapalin. - Metoda B, metoda pro zkušební tělesa s vrubem z trubek z termoplastů, které jsou určeny pro rozvod kapalin. Použití metody A nebo metody B je stanoveno v příslušných normách pro výrobky. Dokument není určen pro použití jako referenční metoda pro stanovení rázové houževnatosti trubek. Referenční metoda je uvedena v ISO 3127, kde je stanovena rázová houževnatost trubek pomocí padajícího závaží. Tento dokument se však může použít pro vědecký výzkum, zkoušení materiálů nebo kontrolu trubek, kdy není možné provést měření v souladu s referenční metodou. Dokument se může použít buď na jednotlivé šarže, nebo na trubky z kontinuální výroby.
