This document specifies requirements and test methods for unsintered polytetrafluorethylene (PTFE) tapes and polytetrafluorethylene (PTFE) strings (PTFE tapes or PTFE strings, for short) which are suitable for sealing threaded metallic joints as specified in EN 10226‑1.

This document covers two classes of PTFE tapes and PTFE strings suitable for fine (F) and coarse (G) threads.

The PTFE tapes and PTFE strings are typically for use in installations for 1st family gases (town gas), 2nd family gases (natural gas) and 3rd family gases (liquefied petroleum gases (LPG)) up to 5 bar, up to 7 bar for hot water of heating systems, and up to 0,2 bar in gas appliances and their auxiliary equipment. The maximum working pressure covered in this document is 20 bar which is relevant to LPG storage. The temperature range is limited to −20 °C to 125 °C.

NOTE            For applications outside the scope of this document (e.g. compressed gases), the purchaser needs to consult the manufacturer.

Anaerobic jointing compounds are covered by EN 751‑1, non-hardening sealing materials (e.g. in the form of jointing compound paste) are covered by EN 751‑2.

This document allows the evaluation of the environmental performance efficiency of the use of domestic swimming pools.

NOTE            This document only covers the operational phase of the basin. All the other stages of the product life cycle, such as the extraction of resources, the acquisition of raw materials, production, distribution, use and end-of-life processing, including final disposal, are not covered by this document.

This document does not apply to:

—    the specific functions of buildings housing domestic indoor swimming pools, such as air treatment or the lighting or insulation of the buildings, etc.;

—    domestic spas covered by EN 17125, or their specific equipment;

—    spas for public use, or their specific equipment;

The present document sets out a method for assessing the energy performance of gas fired appliances combined with heat pump with electrically driven compressor according to EN 16147. It defines a number of daily load profiles for each domestic hot water use, kitchen, shower, bath and a combination of these, together with corresponding test procedures, enabling the energy performances of different gas-fired appliances to be compared and matched to the needs of the user. Where other technologies are combined with a gas-fired boiler or a water heater to produce domestic hot water, specific parts of EN 13203 apply.

The present document does not apply for gas boilers with recovery systems using combustion products as heat source for the electrical heat pump.

When the electrical heat pump does not work for domestic hot water production in the summer period, the present standard is not applicable for energy performances assessing, prEN 13203‑2:2020 is used.

This document is applicable to solar supported gas-fired appliances producing domestic hot water. It applies to a system marketed as single unit or a fully specified system that:
— has a gas heat input not exceeding 70 kW; and
— has a hot water storage tank capacity not exceeding 500 l; and
— is equipped with at least one solar collector; and
— is, with regard to the solar hydraulic circuit, considered as a forced circulation system (definition according to EN ISO 9488:1999).
The appliances covered by this European Standard are described in Annex E (normative).
This document does not apply to thermo-siphon or integral collector storage tank systems according to definitions given by EN ISO 9488:1999.
In principle, the energy consumption of thermo-siphon solar preheat systems and integral collector storage tank preheat systems can also be assessed on the basis of this document. One appropriate procedure for that purpose is to calculate the temperature level of the domestic hot water withdrawn from the thermal solar system for the reference conditions defined in this standard by using the numerical system model and the thermal solar system performance parameters according to ISO 9459 5. Based on the temperature level of the hot water withdrawn from the store the energy consumption of the gas appliance is determined. This determination can either be done by means of calculations or by performing a test according to prEN 13203 2:2020 and using instead of the cold water inlet temperature the hot water temperature withdrawn from the store.
This document is not intended to assess the performance:
— of the solar collector(s), which should comply with EN 12975 1+A1:2010 and EN 12975 2:2006; and
— thermal solar systems and components, which should comply with EN 12976 1:2017 and EN 12976 2:2019.
EN 13203 1:2015 sets out in qualitative and quantitative terms the performance in delivery of domestic hot water for a selected variety of uses. It also gives a presenting the information to the user.
The present document sets out a method for assessing the energy performance of a solar supported appliance.
