This week, Kim said a barrage of missiles launched in recent days were intended for tactical nuclear strikes, while warning Washington that any attempted attack could be met by strikes at American forces in South Korea and Japan. First it must produce miniaturized warheads to fit on the expanding array of short-ranged ballistic missiles it has designed to threaten US troops and their allies in Asia. Kim Jong Un has made clear he wants to build an arsenal of “tactical” nuclear weapons, meaning lower-yield bombs that could be used on the battlefield rather than on whole cities. J2707, USCT, L-423, PF.As North Korea moves closer to its first nuclear test in five years, one of the biggest worries for the US and its allies might be a relatively small blast.

May I advertise and label my formula as copper-free? Am I confident my batch-to-batch and plant-to-plant variation are under control for hexavalent chromium and cadmium? May I use the same manufacturing equipment to produce asbestos-free drum linings? These and many other questions from your R&D team, your customers, and your sales staff can be answered accurately, reliably, technically, and timely when you reach out to the LINK team. Even though chemical analysis was a new endeavor for us, the business challenge and the need to meet the most stringent technical requirements of a new regulation were not. When the friction material industry was faced with the challenge to meet the deadline to comply with the new rules on copper and heavy metals in the states of Washington and California, they came to LINK. Using standard tests like the SAE J2521 or city circuits, or a chassis dynamometer with cold and humid environments to fingerprint the noise characteristics of your product, LINK’s testing capabilities can help you improve your product and differentiate you from your competitors. If a product remains quiet after driving for extended periods, or if it develops severe pedal pulsation due to rotor thickness variation, is a matter of working with a testing partner like LINK who provides cost-effective testing programs with dynamometers and testing centers around the globe. Whether a product is quiet during winter driving conditions, at high temperatures during a mountain descent, or when driving down a parking structure ramp at constant speed, is a matter of using reliable and well-engineered testing systems and testing services. The actual interactions of multiple components, product features, and system response to transient energy input or product conditions are quite difficult to assess without testing. In many areas noise and vibration is still elusive for computer simulation. Issues related to noise, vibration, and harshness (NVH) is still one of the most frequent reasons for come-backs, warranties, and customers switching to a competitor.
