Introduction to rules
A rule is a program used to execute an automatic calculation function and fill in EHS data automatically.
There are different type of rules:
- rules for composition calculation (i.e. COMP rule, HazardComp rules, SVT rules);
- rules for classification calculation (i.e. GHS rules);
- rule for inventory status (NotStat rules);
- rules for local regulation (i.e. EU Seveso III, US SARA Components, etc.).
Some rules can be launched at both Product and PureSub level (i.e. GHS rules), but most of the rules are launched at Product level only.
Most of the rules are provided by SAP and updated twice a year. It is possible to customize standard SAP rules by using external tables / mapping table. This is done by the EH&S team (J.Tran & J.Haupt) , with the validation of each zone process owner. This customization is limited as most of the rules algorithm is owned by SAP.
There are also rules created by Syensqo for additional needs (i.e. calculate the composition to track for each country SVT).
For each rule, there are input data and output data:
- Input data : data used by the rule for the calculation. A same rule can read different type of data (compositions/phrases/numeric values) at different level (Product and/or Pure_Sub):
- The rules that use the product composition as an input are customized to read first the Legal Composition if there is one in the relevant country and then, the Standard composition.
- Output data: result of the rule calculation. It can be a classification, a composition, a phrase, etc.

GHS rules
Training Materials
>> For more detailed information, refer to the GHS rules training item . (broken link)
The GHS rules determine the following information according to each country own GHS requirements:
| GHS classification | GHS labeling | Labeling of special preparations (GHS) / Other hazards (GHS) |
|---|---|---|
|
|
|
Specificity for USA, Canada and Australia: these countries GHS have not adopted environmental hazards, and thus they are optional.
As such environmental hazards are displayed in sub section 2.3 of the SDSs and displayed separately on labels . The GHS_US and AU rules have been divided into:
- GHS_US and GHS_AU that determine Physical and Health Hazards;
- GHS_US Environmental Hazards and GHS_AU Environmental Hazards that consider environment only (GHS US Environment is used for Canada too).
The following countries/zones have their own GHS rule
|
|---|
The GHS_UN generic rule is used for the other countries where GHS is applicable (i.e. India, Hong Kong , ...). This rule follows the last UN Recommendation.
Note that all these GHS rules follow different version of the UN GHS Recommendation. These rules might also rely on different building blocks / categories, even among the same UN revision, and on different generic concentration limits triggering classification of a mixture. As a consequence, with the same product data, you may have different GHS classifications around the world .

- Refer to the link for more information about Listing of assessment phrases (Listing all phrases recognized by the rules and where they must be managed to be used by rules). (broken link)
HazardComp rules
Training Materials
>> For more detailed information, refer to the HazardComp rules training item. (broken link)
- Hazardous Ingredients in Chapter 3;
- Components with Occupational Exposure Limits in Chapter 8;
- Components with Biological Exposure Indices i n Chapter 8;
- Product classification and Sub-Compositions regarding local regulations in Chapter 15 (for some countries);
- Components with DNEL/PNEC values for EU only .
| < 0.1% | > 5 - < 10 % | > 30 - < 40 % | > 80 - < 90 % |
| > 0.1 - < 0.3 % | > 10 - < 15 % | > 40 - < 50 % | > 90 - < 95 % |
| > 0.3 - < 0.5 % | > 15 - < 20 % | > 50 - < 60 % | > 95 - < 99 % |

| > 1 - < 5 % | > 25 - < 30 % | > 70 - < 80 % |
Notifications Status rule
Training Materials

- TSCA (North America);
- DSL-NDSL (Canada);
- AICS (Australia);
- ENCS (Japan);
- KECI (Korea);
- IECSC (China);
- PICCS (Philippines);
- ZTW_INV (Taiwan);
- NZIOC (New Zealand).
Other regulatory lists are available by default, but haven’t been selected in the rule customization yet (for further details, revert to the training item).
This rule set is also outputting (see SVT section):
- Registration according to TSCA 12b , Canadian SNAC and US TSCA SNUR. The same information is outputted by TSCA12b - Stand. Composition Rule.
Two rules, with the same data origin, are available in EHS:
- Stand. compo/ WORLD based on the Standard (or Legal) Composition;
- Exact compo RM / WORLD based on the Exact Composition.
The data maintenance determines which calculations are carried out.
Users have to check the result and always have the possibility to manually modify/remove some instances if the result provided by the rule is not correct. However manual instances have to be managed as recommended on the training item to be correctly displayed on the SDSs.
Local part rules
On top of the previous rules, there are other rules dedicated to a specific country, that enable to complete some information in different sections of the SDS.
The list of all rules is available in the "Grouped rules" part . (broken link)
For the detail of each country local part rules:
- Local Part: Asia Pacific;
- Local Part: Europe - Middle East - Africa; (broken link)
- Local Part: North America;
- Local Part: Latin America. (broken link)
Grouped rules
It is possible to launch several rules at once, by clicking on the title of the group of rules (= grouped rule). By doing so, it will launch all the rules listed under the title. The table hereafter describes the rule launching menu and specify where there is a "grouped rule" and what each grouped rule contains.
- For example, if you double-click on the title 2 - EUROPEAN REGULATIONS RELATED RULES , then it will launch all the rules listed in the block 2, including 2.1, (subgroups 2.1.1., 2.1.2., 2.1.3.), 2.2 and 2.3;

Easy Expert rule
Training Materials
>> For more detailed information refer to the Easy Expert rule training item.
The EH&S Easy Expert enables you to create and edit sets of rules directly in the SAP System. With these sets of rules, you can easily make mass changes to data in any individual specification (ProdCom, PureSub, RealGroup, etc.) or list of specifications.
The sets of rules can be stored in the SAP System to re-use them. Once created, the update of your Easy Expert rule can be done later.
When the EH&S Easy Expert rules are run, the system gives the choice of the following options:
- Write the results to the database immediately;
- Display the results before writing them to the database;
- Run the set of rules as a background job.
Tips and tricks: blocking the launching of a rule
It is possible to prevent the launching of some rules, by using the class " Control data for rule sets ", in chapter 0.
In this class, you have the possibility to select one/several rule/s that you do not want to launch. |
