TL;DR: In this paper, a procedure for applying make-up to the skin, lips, and/or appendages of the skin comprises applying a first layer of a film-forming composition containing in a cosmetically acceptable medium at least one first filmforming polymer and which gives a first film having a hardness d1 (Persoz pendulum) = 20-85 seconds.
Abstract: Make-up system for skin, lips, nails, etc, based on the application of two successive layers of compositions containing film-forming polymers, with the second layer having higher hardness than the first Procedure for applying make-up to the skin, lips, and/or appendages of the skin comprises applying a first layer of a film-forming composition containing in a cosmetically acceptable medium at least one first film-forming polymer and which gives a first film having a hardness d1 (Persoz pendulum) = 20-85 seconds, then applying to at least part of the first layer a second layer of a second film-forming composition containing in a cosmetically acceptable medium at least one second film-forming polymer and which gives a second film having a hardness d2 such that d2-d1 is greater than or equal to 10 seconds

TL;DR: Mirrors with a glass substrate, a silver coating on a surface of the glass substrate and an exposed epoxy paint layer overlaying the silver coating layer have been shown to have scratch resistance determined by the Clemen test showing scratches of less than 10 μm when applying a weight of 1500 g as mentioned in this paper.
Abstract: Mirrors having a glass substrate, a silver coating layer on a surface of the glass substrate and an exposed epoxy paint layer overlaying the silver coating layer. The mirrors show a scratch resistance determined by the Clemen test showing scratches of less than 10 μm when applying a weight of 1500 g; a hardness determined by the Persoz pendulum of at least 250 s; and a commercially acceptable resistance to at least three glues amongst oxime, alcoxy, MS polymer and rubber.

TL;DR: In this article, the authors investigated the use of the pendulum as a simple tool to gain information on hardness and mechanical properties of exterior wood coatings and found that it is a useful tool to study wood coating performances for outdoors.
Abstract: Improving the durability of exterior coatings is essential for the use and development of wood as a building material. In Europe, performances of wood coatings are mainly estimated through visual assessments of panels exposed to weathering. The aim of this work was to investigate the Persoz pendulum as a simple tool to gain information on hardness and mechanical properties of exterior wood coatings. The influence of the substrate and the coating thickness has been studied to figure out the limits of the test method. Through a comparison with tensile tests performed on free films, Persoz pendulum was found to be relevant as a simple tool to estimate mechanical properties of the coating film. Finally, Persoz hardness was assessed on several coatings exposed to 4032 h of artificial weathering. Results have shown that the pendulum hardness test is a useful method to study wood coatings performances for outdoors.
