Classification of environmental conditions - Part 3-5: Classification of groups of environmental parameters and their severities - Ground vehicle installations
Käsitlusala: IEC 60721-3-5:2026 classifies the groups of environmental parameters and their severities to which a product, not forming part of the vehicle, is subjected when installed on or in a ground vehicle. Such products are for example radios, communication systems, fare meters, flow meters for liquids transported by the vehicle, for example milk, petroleum products, etc. Vehicles where products can be permanently or temporarily installed include
- road vehicles: passenger cars, commercial vehicles, special vehicles, towing vehicles, trailers, mopeds, motorcycles,
- rail vehicles: trains, trams,
- tracked vehicles: excavators, cranes, rubber tracked vehicles,
- overland vehicles: four-wheel drive cars, tractors, snow scooters,
- handling and storage vehicles: fork-lift trucks (manual and robot), luggage transporters, and
- self-propelled machinery: diggers, harvesters.
This third edition cancels and replaces the second edition, published in 1997. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) most classes have been replaced by completely new classes based on the use of additional information obtained from referenced Technical Reports;
b) Table 1 through to Table 7 have been reviewed and updated;
c) the content of Annex A and Annex B has either been incorporated into the main body of the document or deleted.

Neutral salt spray test — Results of an international interlaboratory test and conclusions for practical application
Käsitlusala: The objective of this document is to conduct a neutral salt spray test in accordance with ISO 9227. The test is a proven method for assessing the corrosion protection of coatings of components such as bolts. For this reason, two coating variants were chosen for conducting the tests on hexagon bolts with a size of M6 × 50. The bolts were examined at specified points in time and the time of occurrence of grey veil, white rust and red rust was documented. The corrosivity of the salt spray was determined by means of two methods and also documented in an evaluation form. These two methods are the assessment of the mass loss of an uncoated steel panel as specified in ISO 9227 as well as the determination of the time until appearance of red rust on hot-dip galvanized steel panels in accordance with ISO 4042 and ISO 10683.
The processing steps are specified in detail in a manual that was provided to the test participants. If followed precisely, these instructions allow for a comparative analysis of the results from the individual labs and make it possible to determine the reproducibility of the salt spray test. Another objective is to compare the two methods used to determine the corrosivity of the salt spray in order to establish the suitability of these methods by comparing the corrosion assessment results obtained for the bolts. In addition, the normative operating parameters (temperature in the test cabinet, collection rate, pH and density or NaCl concentration of the solution collected) were documented for every inspection date in order to ascertain whether there is any correlation with the results of the corrosion assessment performed on the bolts.

Keskkonnatingimuste klassifikatsioon. Osa 3: Keskkonnaparameetrite rühmade klassifitseerimine ja nende mõju. Jagu 5: Maasõidukite paigaldised (IEC 60721-3-5:1997)
Käsitlusala: Käesolevas standardis klassifitseeritakse keskkonnatingimused, mis mõjutavad maas õidukitele paigaldatud, ent sõiduki osade hulka mittekuuluvaid tooteid. Sellisteks toodeteks on näiteks raadiovastuvõtjad, sidesüsteemid, sõidumeerikud, sõiduki abil transporditavate vedelike (nt piim, naftatooted) mõõturid. Püsivalt või ajutiselt paigaldatud tooted võivad esineda muuhulgas järgmistes sõidukites: - maanteesõidukid: sõiduautod, veoautod, erivedukid, puksiirid, treilerid, mopeedid, mootorrattad jne; - rööbasveerem: rongid, trammid, kraanad jne; - põllutöömasinad: neljarattaveoga veokid, traktorid, lumesahad jne; - laadimis- ja tõstemasinad: mootortõstukid (käsijuhitavad ja robotid), pagasiveokid jne; - liikurmasinad: ekskavaatorid, kombainid jne. Ehkki käesolev standard pole koostatud sõidukite osi moodustavate seadmete kohta, võib keskkonnatingimuste klassifitseerimist kasutada teatud vahetatavate osade puhul, mis on paigaldatud sõidukile sarnaselt ja samadesse asukohtadesse kui tooted, mis ei kuulu sõiduki osade hulka. Kaasatud on ainult need mõjuvad tingimused, mis võivad tooteid kahjustada.
