This International Standard specifies a test method to determine the degree and rate of aerobic biodegradation of plastic materials when settled on marine sandy sediment at the interface between seawater and the seafloor, by measuring the evolved carbon dioxide.

This test method is a simulation under laboratory conditions of the habitat found in different seawater/sediment-areas in the sea, e.g. in a benthic zone where sunlight reaches the ocean floor (photic zone) that, in marine science, is called sublittoral zone

The determination of biodegradation of plastic materials buried in marine sediment is outside the scope of this International Standard.

Measurement of aerobic biodegradation can also be obtained by monitoring the oxygen consumption, as described in ISO 18830.

The conditions described in this International Standard may not always correspond to the optimum conditions for the maximum degree of biodegradation to occur.

This document specifies the measurement method and conditions to obtain reproducible and comparable noise levels on-board all kinds of vehicles operating on rails or other types of fixed track, hereinafter conventionally called “unit”, except for track maintenance vehicles in working modes.

NOTE       For constant speed tests the concept of “comparability” needs further caution, as this term is used as well to classify the measurement precision grade related to track roughness and track decay rates given in this document. Nevertheless, the measurement may be acceptable as type test on a track of controlled acoustic quality, but not compliant to the track specification given in this document.

This document is applicable to type testing. It does not include all the instructions to carry out monitoring testing or evaluation of noise exposure of passengers or drivers over a whole journey.

This document is not applicable to guided buses.

It provides measurement procedures for vehicle interior noise:

—    when the vehicle is moving at constant speed;

—    when the vehicle is stationary;

—    when the vehicle is accelerating or decelerating;

—    in the driver's cab when an external warning horn is sounding.

NOTE       In general, a vehicle type acceptance test would require only a selected subset of these tests to be performed.

It does not provide measurement procedures for:

—    audibility or intelligibility of any audible signals;

—    assessment of warning devices other than warning horns.

The assessment of noise exposure of train crew due to operational conditions is not in the scope of this document.

The results may be used, for example:

—    to characterise the noise inside these units;

—    to compare the internal noise of various units on a particular track section;

—    to collect basic source data for units.

The test procedures specified in this document are of engineering grade (grade 2), that is the preferred one for noise declaration purposes, as defined in EN ISO 12001. If test conditions are relaxed for example as done for monitoring of in-service trains, then the results are no longer of engineering grade.

The procedures specified for accelerating and decelerating tests are of survey grade.

This document specifies the requirements for safety systems which protect a vessel, a system of vessels, piping, accessories or assemblies from exceeding operating conditions.

It is also applicable to safety related indicators and alarms, signals and warning devices when used in safety systems.

Equipment connected together by piping of adequate capacity, free from potential blockages and which does not contain any valve that can isolate any part from the safety system, can be considered as a single pressure system when considering the requirements for overpressure protection.

Safety systems include the interconnections between the equipment to be protected and any discharge location. This location can either be an outlet to atmosphere or the entry into a closed disposal system.

NOTE          The scope of this document and its relationship to the safety accessories and other protective devices described in the Pressure Equipment Directive are shown in Annex E.

This standard specifies the requirements, also known as “relifing requirements”, for the planned, intentional storage, control, and removal from storage of electronic, electrical and electromechanical parts which are intended to be used for space applications.

This standard covers the relifing of all components as defined by ECSS-Q-ST-60 and ECSS-Q-ST-60-13.

The relifing process is a lot quality control activity.  The inspections and tests defined do not constitute an up-screening or up-grading of components to a higher level of quality than procured to.

In line with ECSS-Q-ST-60, this standard differentiates between classes of components through different sets of standardization requirements.

The classes provide levels of trade-off between assurance and risk. The highest assurance and lowest risk is provided by Class 1 and the lowest assurance and highest risk by Class 3. Procurement costs are typically highest for Class 1 and lowest for Class 3. Mitigation and other engineering measures can decrease the total cost of ownership differences between the three classes. The project objectives, definition and constraints determine which class or classes of components are appropriate to be utilised within the system and subsystems.

Class 1 components are described in Clause 4, 5 and 6

Class 2 components are described in Clause 4, 5 and 6

Class 3 components are described in Clause 4, 5 and 7

The requirements of this document apply to all parties involved at all levels in the integration of EEE components into space segment hardware and launchers.

This standard is applicable to all EEE parts covered by ECSS-Q-ST-60 and used in space programmes.

This standard is not applicable to dice.

This standard may be tailored for the specific characteristic and constrains of a space project in conformance with ECSS-S-ST-00.
