This document specifies a laboratory test method to determine the degree and rate of aerobic biodegradation level of plastic materials. This test method can also be applied to other materials.
Biodegradation is determined by measuring the CO2 evolved by the plastic material when exposed to marine sediments sampled from a sandy tidal zone and kept wet with salt-water under laboratory conditions.
This test method is a simulation under laboratory conditions of the habitat found in sandy tidal zone that, in marine science, is called eulittoral zone.
The conditions described in this document might not always correspond to the optimum conditions for the maximum degree of biodegradation to occur.
Deviations from the test conditions described in this document are justified in the test report.

This European Standard applies to roller brake testers (brake test benches) designed for roadworthiness tests on categories M2, M3, N2, N3, O3 and O4 vehicles and that might be also used to test M1, N1 categories.
This European Standard covers fixed-bed roller brake testers with or without inspection pits and whose chassis are inside or outside the building.
This European Standard is not covering mobile roller brake testers.
These roller brake testers are fitted to produce measurements for testing and assessing the efficiencies of the brake systems equipping vehicles in the above-cited categories.
The users of the roller brake tester are all kind of staff that for any reason operates the roller brake testers (e.g staff working in public transport, vehicle rental, vehicle maintenance, vehicle repair, training, test laboratories and vehicle inspection sectors,...).
This document is applicable to roller brake testers manufactured 12 months after the date of its publication as EN.

This document specifies a laboratory test method for determining the degree and rate of the aerobic biodegradation level of plastic materials. Biodegradation is determined by measuring the CO2 evolved from plastic materials when exposed to seawater sampled from coastal areas under laboratory conditions.
The conditions described in this document might not always correspond to the optimum conditions for the maximum degree of biodegradation, however this test method is designed to give an indication of the potential biodegradability of plastic materials.
NOTE This document addresses plastic materials but can also be used for other materials.

This document specifies test methods for the determination of the degree of disintegration of plastic materials exposed to marine habitats under real field conditions.
The marine areas under investigation are the sandy sublittoral and the sandy eulittoral zone where plastic materials can either be placed intentionally (e.g. biodegradable fishing nets) or end up as litter due to irresponsible human behaviour. This depends on their physical characteristics, form and size of the materials, and on water currents and tidal movements.
This document specifies the general requirements of the apparatus, and the procedures for using the test methods described.
The determination of the level of disintegration of plastic materials exposed to pelagic zones such as the sea surface or the water column above the seafloor are not within the scope of this document.
This document is not suitable for the assessment of disintegration caused by heat or light exposure.
The described field test is a disintegration test and not a biodegradation test. Therefore, it cannot be used for demonstrating biodegradation or for making unqualified claims such as "biodegradable in marine environment" and similar.

IEC 62037-3:2021 is available as IEC 62037-3:2021 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
IEC 62037-3:2021 defines the impact test on coaxial connectors to evaluate their robustness against weak connections and particles inside the connector, as independently as possible from the effects of cable PIM (passive intermodulation). For other connectors (e.g. panel mounted connectors), the cable can be replaced by an adequate transmission-line (e.g. airline, stripline). In order to evaluate the effects of mechanical stresses on the connectors, a series of impacts is applied to the connectors while measuring the PIM. This second edition cancels and replaces the first edition published in 2012. This edition includes the following significant technical changes with respect to the previous edition:
a. impact method changed to utilize a steel ball rather than a brass rod;
b. impact energy required to test each connector type added;
c. method added to calculate impact energy for connector types not listed in the document.

IEC 62037-1:2021 is available as IEC 62037-1:2021 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 62037-1:2021 deals with the general requirements and measuring methods for intermodulation (IM) level measurement of passive RF and microwave components, which can be caused by the presence of two or more transmitting signals. The test procedures given in this document give the general requirements and measurement methods required to characterize the level of unwanted IM signals using two transmitting signals. The IEC 62037 series addresses the measurement of PIM, but does not cover the long-term reliability of a product with reference to its performance. This second edition cancels and replaces the first edition published in 2012. This edition includes the following significant technical changes with respect to the previous edition:
a. clarification added that test equipment may utilize pulsed generators to reduce power consumption;
b. heating effect differences in the device under test noted in Annex B for tests conducted using pulsed generators;
c. guidance added in Annex B to improve probability of detection of short duration PIM events while dynamic testing.
