Nadcap AMS2750F & CQI-9 标准-Fornitore globale

Nadcap is developed by the Functional Review Institute (PRI) and provides an officially certified quality assurance system for a range of special processes and products. These products are used in the aerospace industry. It was first proposed by Boeing and is now adopted by Western aerospace manufacturers.

Nadcap is becoming increasingly important in the aerospace industry and has been recognized by relevant units such as GE Aviation, Rolls Royce, Mortimer, Snecma, French Tebomeca, Boeing, Walter Aircraft Industries, Bombardier, Honeywell, Hamilton Sundstrand, and Sikorsky Aircraft Company. Equipment manufacturers and end-users must comply with the requirements of SAE AMS 2750F. According to this standard, ovens and industrial furnaces are defined for temperature uniformity and control instrument types.

Carbolite Gero has accumulated a wealth of experience in the aviation industry, providing users with various solutions that meet their needsAMS2750F、CQI-9Standard ovens and industrial furnaces.

Equipment that meets the AMS2750F standard must specify the following requirements:

temperature range
Temperature uniformity requirements or grades: 1, 2, 3, 4, 5, 6 (see below for details)
Temperature instruments or types: A, B, C, D, D+, E (see below for details)
Average temperature zone size - H x W x D
Temperature uniformity test (TUS) requirements: loaded or empty furnace
System Accuracy (SAT) Requirements

Classification of Nadcap system levels for ovens/muffle furnaces

grade	Temperature uniformity
1	± 3°C
2	± 5 °C / ± 6 °C
3	± 7 °C / ± 8 °C
4	± 10°C
5	± 14°C
6	± 28°C

_{For Class 1 furnaces, the temperature uniformity is ± 3 ° C, and the volume of the oven chamber is much larger than that of the uniform temperature zone. If the volume of the uniform temperature zone is 600 mm x 600 mm x 600 mm, the recommended furnace volume is at least 800 mm x 800 mm x 800 mm}

Nadcap instrument type

The types of control instruments are divided into A, B, C, D, D+, or E. The differences between them are shown in the table below, as well as the instrument serial numbers used to record their data and the recording thermocouples installed in the temperature equalization zone.

	Instrument composition	Type A	Type B	Type C	Type D	Type D+	Type E
(1)	Control instrument with temperature display	X	X	X	X	X	X
(2)	Temperature control sensor	X	X	X	X	X	X
(3)	Process recorder	X	X	X	X	X
(4)	Over temperature protection instrument	X	X	X	X	X
(5)	Over temperature protection sensor	X	X	X	X	X
(6)	Multi channel graphic recorder (or separate channel using process recorder)	X	X	X
(7)	High temperature sensor connected to multi-channel recorder	X
(8)	Low temperature sensor connected to multi-channel recorder	X
(9)	Load sensor connected to multi-channel recorder	X	X	X
(10)	Sensors used for recording in each temperature control zone					X

Nadcap AMS2750F&CQI-9 Standard - Example

GP 450A universal oven that meets Nadcap standards

HRF 7/324 high-temperature air circulation oven, control panel installed on the side, fully meets AMS2750F standard

Three customized vertical circulation ovens that meet aerospace standards

HRF 7/324 upper door high-temperature air circulation oven, in compliance with AMS2750F aviation standard

The system integrates three furnaces to meet the heat treatment process requirements of AMS 2750F, secondary furnace, and Class D instruments.
