This document specifies test methods for assessment of the moisture conditions of any kind of subfloor prior to the installation of levelling compounds and/or floor coverings or parquet floors bonded with adhesives. The methods are independent from subfloor chemical composition or materials and applicable with available equipment.
For some highly reactive cement based compositions (e.g. ternary systems) the manufacturer might recommend a specific time when the subfloor is ready to be covered.
This document describes the methods in detail and includes a protocol template for documenting the measured values.

This document specifies a method for determining the longitudinal reversion of thermoplastics pipes, to be carried out in either a liquid or in air. In case of dispute, heated liquid is used as the reference.
This International Standard is applicable to all thermoplastics pipes with smooth internal and external walls of constant cross‑section. It is not applicable to non‑smooth structured‑wall thermoplastics pipes.
The parameters appropriate to the pipe material and recommendations for the maximum levels of reversion as a function of the pipe material are given in Annex A.
This method is applicable for pipes of wall thickness ≤16 mm.

This document specifies a method of determining the tear resistance of a plastic film under specified conditions. It is applicable to products that, because of their flexibility, do not tear when clamped between the grips of a tensile testing machine. The method makes it possible to compare samples of different products provided their thickness does not differ by more than 10 %.

1.1 This document describes two methods for identification of antidegradants (antioxidants, antiozonants and stabilizers) by thin layer chromatography, which can be present in raw rubber, unvulcanized compounded rubber, or rubber products.
Method A is a simplified method provides for the identification of known materials and may be used to check the presence or absence of a particular antidegradant which should be present.
Method B is a more detailed method enables a greater degree of separation of the spots to be obtained and therefore may be used to detect and identify an unknown antidegradant.
1.2 Antidegradants to which these methods are applicable include phosphited polyalkyl phenols, substituted bisphenols, secondary amines, substituted cresols and substituted p-phenylenediamines. Examination for other types of antidegradants is possible, provided that the requirement of 12.1 is met.

This document specifies the methods for determining characteristics for grouts used in internal and external installation of ceramic tiles.
This document does not contain performance requirements or recommendations for the design and installation of ceramic tiles.
The following test methods are described:
— Determination of flexural and compressive strength (9.1);
— Determination of water absorption (9.2);
— Determination of shrinkage (9.3);
— Determination of resistance to abrasion (9.4);
— Determination of chemical resistance (9.5).
Grouts for ceramic tiles can be used also for other kinds of tiles (natural and agglomerated stones, etc.), if they do not adversely affect the stones.
WARNING — This document can involve hazardous materials and operations. It is important that persons using this document are familiar with normal laboratory practice. This document does not purport to address all the safety problems, if any, associated with its use. It is the responsibility of the user to establish appropriate safety and health practices and to ensure compliance with any European and national regulatory conditions.

This document describes methods of evaluating the resistance of vulcanized and thermoplastic rubbers to the action of liquids by measurement of properties of the rubbers before and after immersion in test liquids. The liquids concerned include current service liquids, such as petroleum derivatives, organic solvents and chemical reagents, as well as reference test liquids.

This document specifies requirements for materials used for moulded seals made of thermoplastic elastomers (TPEs) for joints in:
a) thermoplastic piping systems for non-pressure wastewater discharge (intermittent flow at up to 95 °C) inside buildings;
b) thermoplastic piping systems for non-pressure underground drainage and sewerage (continuous flow at up to 45 °C and intermittent flow at up to 95 °C);
c) thermoplastic rainwater piping systems.
General requirements for finished joint seals are also given; any additional requirements for a particular application are specified in the relevant product standards taking into account that the performance of pipe joints is a function of the seal material properties, seal geometry and pipe joint design.

This International Standard specifies requirements for packaged sterile rubber gloves intended for use in surgical procedures to protect the patient and the user from cross-contamination. It is applicable to single-use gloves that are worn once and then discarded. It does not apply to examination or procedure gloves. It covers gloves with smooth surfaces and gloves with textured surfaces over part or the whole glove.
This International Standard is intended as a reference for the performance and safety of rubber surgical gloves. The safe and proper usage of surgical gloves and sterilization procedures with subsequent handling, packaging, and storage procedures are outside the scope of this International Standard.

This document specifies specifications and test methods for elastomeric seismic isolators used for buildings to guarantee high-durability and high-performance.
It is applicable to elastomeric seismic isolators used to provide buildings with protection from earthquake damage. The isolators covered consist of alternate elastomeric layers and reinforcing steel plates. They are placed between a superstructure and its substructure to provide both flexibility for decoupling structural systems from ground motion, and damping capability to reduce displacement at the isolation interface and the transmission of energy from the ground into the structure at the isolation frequency.
