Notes:

(1) The table filled in accordance with contract demand of customers;

(2) If the customer has control sample needs to provide control sample number, by the customer to buy their own; for example, sales staff and buy, the control sample Shanghai shipped separately;

(3) If the client application is a special application, and are willing to cooperate to provide samples for curve development, the customer must provide accurate sample elements in the table, and to ensure uniformity of the sample, but not as an instrument of this type of curve acceptance criteria;

Installation and Commissioning of Full Spectrum Direct Reading Spectrometer DW-TY-9000

1. Delivery check and storage

After the buyer receives the goods, you should check the packaging is intact. As packaging is damaged or corrupted direct reading spectrometer, the user should keep relevant evidence and promptly notify the seller, with the seller to the responsible party claim. Otherwise, assume self-destruction of the goods by the buyer.

After the equipment arrived at the buyer, the buyer should be placed in the instrument temperature 0℃ ~ 45℃, humidity 20% to 80% of the indoor environment in custody. Before installing the engineer does not arrive, the buyer can not be allowed out of the box, otherwise regarded as acceptance of goods.

2. Installation and Commissioning

Instruments arrive within a month, the buyer should have the installation conditions and notify the seller installed.

After installation engineers arrived, along with the packing list one by one to check received by both parties, representatives of both parties to fill the packing list in duplicate entries in acceptance based on test results and signed. If missing parts on the acceptance of a single note by the installation engineer and immediately notify the seller sent it to us.

Instruments arrive within two months the buyer still have installation conditions, or cause damage to the instrument in custody, the seller is entitled to require the buyer to pay the additional installation costs, all costs for equipment damage caused by the formation of custody shall be borne by the buyer.

In instrument installation and commissioning, the buyer should be given to facilitate the installation engineer working conditions. Because if the buyer does not have the installation conditions resulting installation engineers to the scene after the unable to work and staying two days (or more), installation engineers can directly return, and to assume the installation engineer during detention by the buyer of the full cost, including transportation to and installation engineers fees, room and board, fees and subsidies.

If the content is not individual elements within a selected range of standard content, or after installation of its RSD, SD value exceeds the allowable value, the two sides should negotiate, analyze problems and propose solutions to problems.

After acceptance, representatives of both parties sign it in duplicate on the acceptance of a single installation.

Note: For customers with samples to create a curve as a standard case, because the customer can not guarantee uniformity of standards, samples of impurities can not be completely sure, the sample providers do not have the qualifications national standard production, so the results of the analysis can not be used as acceptance criteria .

Installation steps:

1) Engineer to the site according to the instrument installation procedures for installation, commissioning.

2) Test sample selection:

According to the buyer’s analysis of the content of the sample, the seller and the buyer to jointly negotiate to determine, select a set of suitable for the user’s daily analysis of the standard sample (the set of the buyer to provide or negotiate with the seller purchasing), as the instrument of acceptance. The standard sample selection principle should be based on the principle of the content of the daily production of the buyer.

3) Test:

After the instrument, the instrument temperature, pressure and argon atmosphere after the instrument to meet the requirements of the instrument, by the seller and the installation engineer with a set of pre – determined, the establishment of the instrument, and then the two sides agreed to take a sample of the standard sample (usually not containing high and low standard sample) for precision testing. General provision of 4~6 points (excluding abnormal excitation) of data to calculate.

After acceptance, the installation of the negotiators in duplicate sign acceptance certificate.

Note: for customers to provide samples as the standard sample to establish the curve, because the customer standard sample uniformity can not guarantee, the sample impurities content can not be completely determined, the sample provider does not have the national standard material production qualification, so the analysis results can not be used as the aaceptance index.
