What is eCl@ss?
eCl@ss is the international standard for unified and consistent classification of products, materials and services along the entire supply chain. In addition to providing the option of describing each individual product in a unique way, eCl@ss is also implemented as a product-grouping, company-internal organizing system with the features of a commodity code. eCl@ss e.V. is the organization that defines, develops and distributes this standard internationally across industries.
 Which benefits does eCl@ss offer?
- is based on national and international standards.
- covers all products, materials (direct, indirect) and services.
- combines requirements of trade and development.
- contains sets of properties for material groups.
- offers a keyword search (instead of navigation through complex structures) to make the search for the correct material group much easier especially for occasional users.
- can be implemented in eCommerce as well as with material- and facility management and in product information systems.
- can be downloaded in several languages on http://www.eclassdownload.com.
- is supported by a wide, industrial base in Germany and Europe.
- is supported internationally – with the help of regional partners in Europe, the USA and Asia eCl@ss will be increasingly used internationally in the future.
- is already employed by many international enterprises and their suppliers in Germany and Europe.
 Why does it make sense to classify using eCl@ss?
Manufacturers and suppliers that provide products and services classified according to eCl@ss, can reach all existing and potential customers around the world - even without knowledge of foreign languages - by classifying their offering only once. You not only speak the same system language, eCl@ss ensures proper translations. Purchasers or consumers can clearly and quickly identify and order all products and services with the eCl@ss codes using product databases, merchandise information systems or electronic catalogues. Please also have a look at an overview of typical use cases.
 In which business areas/processes can eCl@ss be implemented?
eCl@ss can be implemented in all business areas/processes. The eCl@ss system accompanies your products and services along the entire supply chain, from development to disposal. Please also have a look at an overview of typical use cases.
 Is eCl@ss suitable for electronic data exchange?
Yes, the standardized data structure provides the ideal foundation for electronic data exchange without system failures. Please also have a look at an overview of typical use cases.
 Who finances eCl@ss?
eCl@ss is financed by the contributions of the members of eCl@ss e.V., project activities and business models with cooperation partners. Therefore, members of eCl@ss e.V. enjoy especially interesting advantages.
 What advantages does eCl@ss provide over UNSPSC?
At first glance, the classification systems eCl@ss and UNSPSC seem to have many similarities. These systems are actually structured in a similar way. Both provide a 4-tier classification hierarchy.
UNSPSC was originally developed for statistical evaluation purposes such as e.g. spent analysis. The focus was not on identification of individual materials and therefore UNSPSC does not have any sets of properties and does not plan to include any. A detailed comparison of eCl@ss, UNSPSC, GPC and the CPV is to be found in the CEN-Project CC3P.
The development of the eCl@ss system was based on several different requirements. It was intended to be a standardized classification system which could not only be used to perform statistical evaluations, but also to seek, find and describe products in a targeted manner. For this reason, standard sets of properties are assigned to commodity classes (on the 4th level of the classification structure). The properties are used to described the classified products. Keywords represent a special advantage compared to other classification system such as the UNSPSC. They enable even the inexperienced user to quickly find the right class for a specific product.
Generally, all classification systems have their use cases. Therefore, the choice for the one or the other system depends on the users' requirements. eCl@ss is generally suitable for all use cases along the supply chain.
 What purpose do the sets of properties serve?
Sets of properties serve for unified and comparative description of products. The properties within a set of properties are unique and therefore allow for targeted search. eCl@ss is the only classification system worldwide which uses DIN/[ISO] standardized properties. Product descriptions according to eCl@ss therefore also meet standards requirements.
 Does eCl@ss provide product descriptions?
No, the product manufacturers or suppliers provide the product descriptions. However, eCl@ss provides the description structures required for this.
 How do I provide data in conformance with eCl@ss?
If your partner requests that you provide data in conformance with eCl@ss, then they require proper allocation of products to the classes of the 4th level of the eCl@ss classification system with indication of the eCl@ss version. If material descriptions are to be provided in conformance with eCl@ss, then entries have to be made in the property fields required in each case. However, in most cases it is not necessary to evaluate all properties, but only those required by the order.
 How do I find the correct class in eCl@ss?
eCl@ss e.V. provides several options of [searching http://www.eclasscontent.com] in eCl@ss on its [web site http://www.eclass.eu]. The searches by class, property and value names or keywords can be especially helpful to new users or those who only use the service periodically. eCl@ss returns all classes, properties or values containing the search term. Those who make regular use of the service have the option of researching within the eCl@ss structure using hierarchical class searches. Use of this function requires certain knowledge of the class structures and the contents of these structures.
 What should I do if I cannot allocate my product?
If you are not able to find precise class allocation for the sought product at the fourth level, then you should allocate it to an appropriate group or main group. Classes with the class code 90("unspecified") at the end are allocated to each group and each main group at the fourth level. You can allocate products to these classes, for which the group or main group is appropriate but for which no more precise allocation is possible. In case something is missing from your point of view, you may always request missing content on the [eCl@ss ContentDevelopmentPlatform http://www.eclass-cdp.com].
 What is the difference between a group "parts" (xx-xx-xx-91) and a group "accessories (xx-xx-xx-92)?
eCl@ss knows various descriptive codes: the groups xx-xx-xx-91 "parts" and xx-xx-xx-92 "accessories". The difference between parts and accessories in the allocation of products is defined in eCl@ss as follows:
- “parts” are objects which are of spare part nature
- “accessories” are objects which extend the possibilities of a machine or apparatus, i.e. they are rated as “Add-ons”. The most important distinction against the “part”-group is that the machine, apparatus is able to carry out its intended operation even without these objects.
 Is there a software which enables automatic classification of products?
Fully automated classification is not possible. Tools to simplify classification are available. Our cooperation partners provide various tools for this purpose.
 How is a value list used?
Starting with eCl@ss release 7.0, eCl@ss distinguishes between value lists that are restricted and value templates that are suggested. The value list is a restrictive, i.e. closed list of valid values for a property. That means that these and no other values are valid specifications of a property.
The value template is a compilation of the most often used specifications (values) of a property. It can, but does not have to be complete. The required value is selected from the template. If the required specification is not found in the value template, then it can be entered manually. Use of the value lists and value templates ensures unified notation of the entries, which simplifies and accelerates subsequent searches in the database. In addition to this, it is possible to use the value identifiers upon transferring data so as not to be hindered by language differences.
 Which properties do value lists have?
 Is it possible to create private classes in eCl@ss?
eCl@ss has reserved the whole segments 98-00-00-00 and 99-00-00-00 for the creation of individual (proprietary) classes. Each user can develop and use these segments for his or her own purposes, but the formal and technical rules laid forth by eCl@ss should be adhered to in all cases.
 Data model
 How many levels does eCl@ss consist of?
eCl@ss is a 4-level classification model. The first level is called a "segment", the second is a "main group", the third is a "group" and the fourth level is a "commodity class". The sets of properties are allocated to the fourth level (commodity class).
 Can the products also be classified at the third level?
The eCl@ss data model is designed in such a way that products and services are classified at the commodity group level (level 4) as only these classes can be described with the help of properties. Data exchange with the eCl@ss classifiction system should only be done if all products and services are classified at level 4. Nonetheless, eCl@ss does not restrict this and can only advise to assign products only to product classes, i.e. commodities on the 4th level.
 Do all properties in a set of properties have to be used?
The use of individual properties of an eCl@ss set of properties depends on the product specifications to be described and the processes in which the sets of properties are to be used. Therefore the use of eCl@ss properties is optional from the association's point of view. eCl@ss does not define mandatory properties. Your decision as to which properties to use from a set of properties depends on your own requirements as well as the needs of your customers and suppliers.

 Quality Management
 How is the quality of classes and sets of properties ensured?
Several committees inspect each change request for correctness with regards to form and content to ensure the high quality of eCl@ss. Each change request has to meet formal criteria which are inspected upon receipt by the eCl@ss office. The required foundation is developed by the Center for Research and Development. The head office forwards the change request to the responsible expert group. The content is inspected with regard to correctness and conformity to the underlying standards (e.g. ISO 13584, IEC 61360, DIN 4002,... ). Requested properties are compared to those in the DIN property server and applications are made for new properties if necessary. The final inspection is done by the Center for Quality Control checking each request with regards to eCl@ss conformity.
 How are the expert groups organized?
An expert group consists of specialists in a single topic area. Among them are manufacturers, retailers and buyers. Normally the area is defined as an eCl@ss specialist area. The expert group is headed by an expert group leader. This person has to be an ordinary member of eCl@ss e.V.
 Which tasks is the expert group responsible for?
The main task for an expert group consists of evaluating submitted change requests. It decides which changes are integrated in eCl@ss. The expert group focuses on its particular topic area. The requirements of the classification and the sets of properties are processed within the expert group. Change requests can be derived within the expert group. Final release of the changes is carried out by the Center for Quality Control. It inspects the completed change requests as regards content and conformity with the rest of the system.
 To which topics are there expert groups?
There are usually expert groups for all segments already included in eCl@ss.

eCl@ss distinguishes between three types of releases and publishes a rather transparent release roadmap. Please see The Release Process.
 How often do new versions of eCl@ss appear?
eCl@ss is a classification systems that ensures its users a high level of planning security. Therefore the publication of eCl@ss release and the release roadmap are announced well in advance. Customer requirements are thereby implemented in an efficient and targeted manner. Please see The Release Process.
 Do I have to download each eCl@ss update?
You do not necessarily have to download each and every update. The current version is always recommended as the standard version for technical reasons. But in the end, the choice of the release used in your systems depends on the release versions of your business partners. If you use eCl@ss for electronic data exchange with your customers or suppliers, it can make a lot of sense to carry out the updates at least once a year to remain up to date. More and more, updates can be installed in a semi or fully automated manner without system conflicts with the help of RUF and TUF.
 What is modified in each update?
The eCl@ss release roadmap comprises three types of releases, the order of which is clearly defined to ensure planning reliability for all users. Please see The Release Process.

 Further Development
eCl@ss distinguishes between three types of releases and publishes a rather transparent release roadmap. Please see The Release Process.
 How long does it take for a change request to be implemented?
The processing time for change requests depends on the type and scope of the change. If a structure already exists and only requires modification, then the request may be integrated as early as the next Minor Release, but is usually integrated in eCl@ss within twelve months. Applications made by eCl@ss e.V. members for integration of new classes and properties will be handled with priority. Requests requiring vast changes to the existing structure can only be implemented every 3-4 years within the context of a major release.
 How can I have new classes integrated in eCl@ss?
Every user has the option to make change and enhancement requests on the eCl@ss ContentDevelopmentPlatform.
 Who is responsible for developing eCl@ss?
eCl@ss is developed by its members and users. The economical use of eCl@ss results in high levels of distribution and use. Therefore change requests are constantly being sent to eCl@ss from outside of the organization. eCl@ss cooperates with requestors to maintain eCl@ss across industry boundaries.
 When will eCl@ss be finished?
A user-oriented classification system requires continual maintenance. This is the direct result of the innovative capacities of the participating companies and the emergence of entirely new sectors. New products are being placed on the market on an ongoing basis and all of theses products require classification in the eCl@ss system.
 Can I work with eCl@ss even if I am not a member?
Yes, we welcome your input in our eCl@ss ContentDevelopmentPlatform which is open to everyone and can be used free of charge after registering once. The contribution is not bound to a membership in the eCl@ss association. The lion's share of the development work is carried out by the expert groups and it is therefore extremely beneficial if this work can be distributed among several parties. However, membership in eCl@ss e.V. has many attractive benefits.
