Our statements:

What is time?

calendar clock

Our entire day is organised by time - dial and hands of a clock are helping us to arrange everyday's life and to provide stability when planning future steps.

Time enables us to put events and experiences in a logical order because time is uni-directional for our perception. We are not able to stop or reverse time - it is streaming from the past to the future and is distinguishing cause and effect.

As the leading European manufacturer of time synchronization solutions hopf Elektronik GmbH has summarized the process from occurence to distribution of time in the whitepaper "What is time" below.

RoHS / WEEE Guidelines

Fulfilment of the RoHS / WEEE Directive

According to German Electrical- and Electronic Equipment Act - ElektroG of 16th March 2005

WEEE - Directive 2002/96/EG on used electrical and electronic appliances

The products of the company hopf are registered with the Stiftung Elektro-Altgeräte Register (EAR) on the German market since 24th November 2005 as follows:

hopf Registration No.: WEEE-Reg.-Nr. DE 25152653
Brand: hopf
Type of Equipment/ Category: 9- Monitoring and control instruments for commercial usage only

The company hopf is entitled and registered as commercial producer only.

RoHS - Directive 2002/95/EG on the restriction of the use of certain hazardous substances in electrical and electronic equipment

All products of the company hopf comply with the stipulated requirements of the Directive on forbidden materials.


hopf products are subject to exemptions according to the stipulated requirements on forbidden materials according to RoHS and the national laws (see §5 ElektroG). However, based on the request of different customers referring to the fulfilment of the Directive on forbidden materials not containing lead, the company hopf uses, only with a few exemptions, components free from lead. Components containing lead are only there in use wherefore lead-free substitutes do not exist on the market yet. As soon as those components are available in lead-free execution, the company hopf will currently use those also.

For appliances / systems which are liable to the Directive on forbidden materials, the maximum allowable portion of lead is 0.1 percent by weight. This corresponds to 1g lead per 1kg appliance. Already on today's estimate, hopf products should exceed this critical value, if any, marginally.

Considering hopf products in customer systems which are subject on forbidden materials as a whole and must therefore be lead-free, and relating to the complete system on average, the limit value of 1g lead per 1kg appliance should be certainly observed.
