A lever, rod, brake beam, hanger, or pin may not be worn through more than 30 percent of its cross-sectional area, cracked, broken, or missing. All pins shall be secured in place with cotters, split keys, or nuts. Brake shoes shall be fastened with a brake shoe key and aligned in relation to the wheel to prevent localized thermal stress in the edge of the rim or the flange.

According to EN ISO 4628, the visual evaluation was focused on blistering, cracking, peeling, chalking, and the extent of biotic infections and mold. Despite almost one year of exposure, no bubbling, peeling, and chalking of the coating film was observed on the surface of the samples; these factors were therefore excluded from the analysis. Most specimens presented cracked and infected films and consequently stained surfaces due to the influence of biotic factors, such as fungi or mold. Cracks in the coating films first appeared on the samples only six months after exposure and then escalated further, as shown in Table 3. The most intense cracking was observed on specimens with solvent-based UV stain applied without plasma pretreatment (BB-030-bp), where larger cracks are extending through the entire coating system. For specimens BB-032-bp, and for the water-based stain applied without plasma, EB-023-bp and EB-024-bp, only the top layer of the coating was affected, whereas the bottom layer remained intact. Very small, barely visible cracks also appeared on untreated samples of tung oil (blue field, Table 3). In comparison with untreated samples, the degree of cracking on plasma-pretreated specimens was significantly reduced. Only one plasma-pretreated specimen exhibited cracks (EB-020-p), albeit to a minimal degree. This positive effect of plasma pretreatments might be attributed to the enhanced wetting and deeper penetration of coatings into the wood surfaces, which has been reported before (Žigon et al. 2020b). This prolongs the time after which cracks appear on the wood and reduces the depth of cracks, which in turn reduces the possibility of wood decay due to infection with biotic decomposition factors. An example of strong cracking after exposure and the as-prepared specimen for comparison are presented in Fig. 5a, b, respectively.

I had several of the varnished decorative hardwood laminated ply panels replaced in the lounge on an air conditioned luxury yacht. Subsequently the woodgrain has reflected in the previously mirror-finish, only on the new panels and we suspect moisture content issues in the wood before it was varnished. The wood and varnish appear otherwise pristine, uncracked and not bubbled or clouded in any way. There is no balancing layer on the reverse of the panels which might obstrust breathing of the panel. Please commenr?

We are shipping some acacia chopping board to colorado ( US) with moisture ranges from 10-14% while shipping from India but once product received all get cracked . So please help us to know what should be required moisture level in Acacia board in final product if we need to restrict wood movement at Colorado . 2b1af7f3a8
