Standard Practice for Designing a Process for Cleaning Technical Glasses
 N C912

Annotation

This practice covers information that will permit design of a rational cleaning procedure that can be used with a glass that is somewhat soluble in many aqueous chemical solutions. Typically, this type of glass is used in applications such as optical ware, glass-to-metal seals, low dielectric loss products, glass fibers, infrared transmitting products, and products resistant to metallic vapors.

In most cases, this type of glass contains high concentrations of oxides that tend to react with a number of aqueous chemicals. Such oxides include B2O3, Al2O3, R2O, RO, La2O3, ZnO, PbO, P2O5, and Fe2O3. The more conventional highsilica glasses are usually more chemically resistant, but the cleaning principles outlined here also apply to them.

This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific hazard statements are given in Section 4 and Table 1.

Общепринятая практика для проектирования процесса для очистки технических очков

Эта практика покрывает информацию, которая разрешит дизайн рациональной процедуры очистки, которая может использоваться со стаканом, который несколько разрешим во многих водных химических растворах. Как правило, этот тип стекла используется в заявлениях, таких как оптическое изделие, печати стекла к металлу, низкие продукты диэлектрических потерей, стекловолокна, инфракрасные передающие продукты и продукты, стойкие к металлическим парам.
