How to calculate the compressive strength of cartons?

Cartons are required to have a certain compressive strength, because after packing goods in the process of storage and transportation, the cartons stacked in the lower layer are under the pressure of the upper cartons. In order to avoid collapse, they must have appropriate compressive strength. The compressive strength of cartons is calculated by the following formula: P = KW (n – 1) In der Formel, P—- carton compressive strength, N W—- Carton weight after loading, N N —- Number of stacking layers K—- [...]

Umweltstress-Screening (ESS) testen

The objective of the ESS test is to eliminate early death parts (including structural, material, manufacturing, shipping, and storage defects) as early as possible before they are assembled into the product to avoid the cost of midproduction impacting timetables and failure during the mission. Stabilization Bake 1. Stabilization Bake Based on MIL – STD – 883 Methode 1008, Condition C rules, the electronic components into constant temperature box, the rated storage temperature, the temperature rise to parts for 24 hours of [...]

Testprinzip und Funktionsweise der Salzsprühprüfkammer

Salt spray test chamber test principle Salt spray test chamber can do four kinds of tests: neutral salt spray test (NSS), copper accelerated acetate salt spray test (CASS), alternating salt spray test, acetate salt spray test (ASS test).Of course, different tests not only require different solutions, but also the design and structure of the box may be different. 1. The temperature of the neutral salt spray test chamber (NSS) is required to be at (35Die Deckkraft bzw. Spreitkraft für diese Dicke kann direkt aus den unten stehenden Umrechnungstabellen für jede der Deckplatten entnommen werden)℃, the humidity is greater than 95%, [...]

Anwendungsunterschied zwischen Kolorimeter und Spektrophotometer

So legen Sie Farbstandards fest, Produkterscheinung verbessern, Farbqualitätskontrolle, und Computerfarbabstimmung?Hier müssen wir ein Farberkennungstool erwähnen – der Farbmesser. Momentan, es gibt viele arten, Marken und Geschäfte von Farbmessgeräten. Einige Kunden sind mit der Farbmessung nicht vertraut. Angesichts verschiedener Arten von Instrumenten, wird es einen großen Preisunterschied und unterschiedliche Messergebnisse geben??Warum werden einige Instrumente der chromatischen Aberration genannt?, und einige sogenannte Spektralfotometer?What are the differences [...]

Kenntnisse in der Farbmessung – über die Beleuchtungs- und Beobachtungsgeometrie von Instrumenten mit chromatischer Aberration

Knowledge of colour measurement About the illumination and observation geometry of chromatic aberration instrumentsThe human eye cannot quantify color correctly, but we can use chromatic aberration instruments and spectrometers to measure color, which is quite simple.And the position relation among the lighting source, the measured sample and the sensor is the illumination observation geometric condition in the color measurement, referred to as geometric condition.Cie15:2004 recommends ten types of reflective sample measurement geometry:1.von:8 Diffuse illumination, 8° receiving, including specular reflection component.The sample [...]
