They are the basis of each offer, each acceptance and each order acknowledgement of the supplier. With placement of the order they become part of the contract with their entire contents. They are valid either for all deliverables and performances that the supplier produces for his customer before conclusion of a possible contract as well as for all future deliverables and performances of the supplier, even if their inclusion will not be expressively agreed upon again.

A liability of the supplier for a damage or deterioration of the object to be tested is excluded.

3.5 Statements concerning the test results are only binding as far as they are included in the written test report of the supplier. For eventual measures that the principal undertakes because of the test results, the latter is exclusively responsible himself.

4.2 If particular official security prescriptions are valid at the place of performance or other special regulations being of importance, the principal will point out this in time before the beginning of the tests to the supplier. The principal will, in addition to that, take care that the concrete local area in which the supplier will perform the test corresponds to the particular security prescriptions.

4.3 The principal is obliged to co-operate as far as this is necessary for the orderly performance by the supplier. He will put at the supplier’s disposal – to the necessary extent – electric current, water, scaffoldings, ladders, steps, crane works, other lifting gears and others and cares for a sufficient lighting at the place of performance.

4.4 For the safe storage of tools the principal will put at the disposal – free of charge – lockable rooms and for the supplier’s testing personnel suitable working and recreation rooms including acceptable sanitary installations as well as special protection clothes and protection devices unless they are not of common use for the supplier’s branch.

5.1 Information about the duration and termination of the inspections are regularly determined and are based on a normal working procedure and are therefore only approximate values, unless the supplier has described the duration of the inspection explicitly in writing. Beginning, duration and termination can be deferred by unforeseen events and circumstances beyond the range of the supplier’s influence.

5.2 In case of force majeure, fire, flooding, natural catastrophes, warlike or terroristic force, measures of laboratory fights, official interferences, obstacles on transport ways as well as in case of other circumstances beyond the supplier’s range of influence like trouble in the management and difficulties with the provision of material and equipment the supplier has the right to postpone the date of the inspection’s termination for the duration of the encumbrance and an adequate phase of restart to the end or to withdraw totally or partially from the contract. A withdrawal declared in that way does not entitle the principal to claim for compensation.

5.3 The supplier only falls into delay when the principal reminds him after beginning of the due date in writing.

6.2 In case of a breach of the principal’s duties, especially with payment delay, the supplier is at any time entitled to take again the inspection documentation and other supplies and services or may claim for their restitution. The enforcement of these rights by the supplier does not pass for a withdrawal from the contract as long as this is not explicitly declared by him in writing.

6.3 If objects of the supply being concerned by the reservation of property of behalf of the supplier are mixed inseparably with other objects not belonging to the supplier, the supplier acquires the joint ownership of the new object in the ratio of the supply object’s value to the other inseparably mixed objects. The principal keeps the joint ownership safe for the supplier.

6.4 The principal may only sell the documentation having been put at his disposal by the supplier and other suppliers and services within the scope of an orderly course of business when he is not in default of payment towards the supplier. By the way it is valid: In case that the service towards the supplier has not already been paid completely at the point of time of the sub-sale to a third person, the principal cedes all claims against the third person from the sub-sale (including value added tax) amounting the payment in arrears to the supplier accepting this, independently from the case if the objects to be supplied will be sold without or after treatment. Upon demand of the supplier the principal has to indicate the sale to the third person and to give all necessary information for the collection and to hand over all documents.

6.5 The principal is not at all entitled to other orders like security conveyance, mortgagings or others. In case of distresses as well as confiscation or other orders by third persons the principal has to inform the supplier without delay and to give him all information and documents that are necessary for the protection of his rights.


7.1 For the suppliers and services the principal will pay the prices agreed upon to the supplier. If the contract partners have not agreed upon explicit prices, the settlement will be done on the basis of the current product and price list at the point of time of the service and/or supply. The product and price list can at any time be changed adequately by the supplier according to his own free decision and with a future effect.

7.2 All prices indicated by the supplier are net prices and are to be understood with the addition of the legal purchase tax as well as eventual travelling and shipment costs.

7.3 All payments fall due upon receipt of the invoice or other requests for payment. They have to be made at the latest until the date of payment agreed upon, or rather, within the period of time agreed upon; in this case the point of time of the receipt of payment is determining. For the beginning of the period of payment the respective date of the invoice or request for payment is determining. If no explicit date of payment is mentioned and no explicit period ot time determined, the respective invoice has to be paid within 14 days after the date of the invoice or the request for payment without any deduction. If the payment does not reach the supplier within the period for payment, or rather, 14 days upon the date of the invoice or the request for payment, the principal will get in default without any further explanation of the supplier.

7.4 In case of orders with a period of time for the performance of more than one month the supplier is entitled to issue partial invoices regarding the already produced suppliers and services.

7.5 If terms of payment are not followed by the principal, the supplier has the right to ask for an immediate payment for all existing claims and make outstanding supplies and services dependent from the payment of outstanding debts and an adequate advance payment for the service to be still rendered.

7.6 If the termination of the supplier’s performance becomes impossible because of a circumstance that he is not responsible for, he can ask for a part of the payment agreed upon for the work done as well as a replacement of the expenses not being included in the reimbursement.

7.7 The principal is only entitled to assert his rights of retention and for settling of accounts with counter-claims, if these rights or claims have been legally stated or accepted by the supplier or not been denied.

If the subsequent performance only possible with disproportionate costs, the supplier may refuse it.

8.4 If there does not take place a subsequent performance within an adequate period of time determined by the principal or if it fails or if it is outrageous for the principal, the principal can at his choice withdraw from the respective contract by fulfilling the legal preconditions, reduce the price or, following the further legal preconditions of § 281 of the German Civil Code, claim for compensation of damage or in some cases replacement of wasted expenses according to application of the following subclause 10. If the principal wants to claim for compensation of damage instead of the service or carry out the correction himself, a failure of the subsequent improvement is only given after the second unsuccessful trial. In case of trivial defects or violations of duty the principal has no right to withdraw from the contract.

8.5 The supplier does not take over any guarantee for damage that occur because of unsuitable or improper use of the deliveries and services of the supplier, if the supplier is not responsible for the damage.
