FAQ - Frequently Asked Questions About the Initial Sample Test Report (ISTR)
First samples are products that are manufactured for the first time under standard and realistic conditions. Any subsequent production and product release of such a product must be based on the initial sample under identical conditions. From the produced batch a determined quantity, which has been agreed with the customer, is released for sampling. Changing production processes generally result in re-sampling or recertification by the customer.
Re-sampling may also be necessary if
- production pauses for more than 12 months,
- the base product is altered (e.g. function) due to a change of purchased parts,
- a change to the product by the customer,
- a change in the manufacturer/supplier approved by the customer (if agreed).
Initial samples and their reporting serve the prevention of errors in series production from the beginning. Here, basic agreements are made between the customer and supplier, which define the characteristics and quality features of the modules in order to manufacture them in series in a clearly defined, reproducible quality.
An initial sample test report allows accurate and unique documentation of the production process. As a result, series modules are reproduced in a consistently optimal quality. Therefore, the module has the same characteristics as the initital sample. The customer benefits of such a performance-oriented production and the production process is made transparent for him. In addition, the company Kuttig Electronic GmbH guarantees a 10 year safekeeping of the ISTR.
The customer releases the initial sample. The supplier (Kuttig Electronic GmbH) commits itself to produce the modules in series under exactly the same conditions. The modules can be called off by the customer as required.
Archiving is performed in accordance with § 257, 1 HGB and § 147 AO.
However, a retention period of 10 years is usually applicable.
This means that the customer agrees to the production methods and the qualitative characteristics of the module.
Product quality is thus confirmed by the customer. This requires a customer signature under the headings marked and the completed documents (refer to identifiable section) should be returned to Kuttig Electronic. You will find a postpaid envelope in the back cover of the folder. The documents indicated in point 5 have to be sent back within 2 months of receipt, otherwise the result of the inspection is considered as released.
The customer releases the sample, but only under the condition that the points complained about will be improved by the supplier. This requires a customer signature under the headings marked and the completed documents (refer to identifiable section) should be returned to Kuttig Electronic. You will find a postpaid envelope in the back cover of the folder. The documents indicated in point 5 have to be sent back within 2 months of receipt, otherwise the result of the inspection is considered as released.
A rejection is done by a negative evaluation of the initial sample. The sample will be returned and the production has to be stopped. After agreement, an improvement can be carried out. The documents indicated in point 5 have to be sent back within 2 months of receipt, otherwise the result of the inspection is considered as released.
