ISO 11357-1:2016 specifies several differential scanning calorimetry (DSC) methods for the thermal analysis of polymers and polymer blends, such as
- thermoplastics (polymers, moulding compounds and other moulding materials, with or without fillers, fibres or reinforcements),
- thermosets (uncured or cured materials, with or without fillers, fibres or reinforcements), and
- elastomers (with or without fillers, fibres or reinforcements).
ISO 11357-1:2016 is intended for the observation and measurement of various properties of, and phenomena associated with, the above-mentioned materials, such as
- physical transitions (glass transition, phase transitions such as melting and crystallization, polymorphic transitions, etc.),
- chemical reactions (polymerization, crosslinking and curing of elastomers and thermosets, etc.),
- the stability to oxidation, and
- the heat capacity.
ISO 11357-1:2016 specifies a number of general aspects of differential scanning calorimetry, such as the principle and the apparatus, sampling, calibration and general aspects of the procedure and test report common to all following parts.
Details on performing specific methods are given in subsequent parts of ISO 11357 (see Foreword).

This European Standard specifies the general requirements and applies to heat meters. Heat meters are instruments intended for measuring the energy which in a heat-exchange circuit is absorbed (cooling) or given up (heating) by a liquid called the heat-conveying liquid. The meter indicates heat in legal units.
Part 3 specifies the data exchange between a meter and a readout device (POINT / POINT communication). For these applications using the optical readout head, the EN 62056-21 protocol is recommended.
For direct or remote local readout of a single or a few meters via a battery driven readout device, the physical layer of EN 13757-6 (local bus) is recommended.
For bigger networks with up to 250 meters, a master unit with AC mains supply according to EN 13757-2 is necessary to control the M-Bus. For these applications the physical and link layer of EN 13757-2 and the application layer of EN 13757-3 is required.
For wireless meter communications, EN 13757-4 describes several alternatives of walk/drive-by readout via a mobile station or by using stationary receivers or a network. Both unidirectionally and bidirectionally transmitting meters are supported by this standard.

This Technical Report applies to industrial and district heating supply by means of high-temperature water heating facilities (flow temperature > 100 °C). It also applies to high-temperature water heating facilities (flow temperature ≤100 °C) that are directly connected to district heating net-works. In this Technical Report, the aforementioned supply variants will, in the following, be referred to as "district heating facilities". This Technical Report applies without limitations to new facilities. For existing district heating facilities, the application of this Technical Report is recommended in order to prevent faults due to the chemical composition of the circulation water that would affect the facilities' safe operability and availability.
