NSS never lets the specimen dry. Real corrosion lives in the wet→dry transition. JASO M609-91: 2h salt + 4h drying at 60°C + 2h humid = 1 cycle. GB/T 9789-2008: SO₂ acid rain, 24h/cycle. One standard is a floor. Two is a spec. https://t.co/Vcn6KX3Ioe #Solaracks#BeSupported
JIS Z 2371 vs GB/T 10125 NSS hours: directly comparable. Both = ISO 9227. Same salt, temp, pH. Ruspert 2,000h includes a pre-damage drill test — that's their addition, not the standard. Multi-alloy zinc diffusion: 4,000h+. The gap is real. https://t.co/Vcn6KX3Ioe
600kW on a TPO membrane roof. Every base anchored to structural deck. Boot flashings hot-air welded to the existing membrane — same material, zero seam. Aluminum hardware. Roof warranty intact. The roof dictates the method. #Solaracks#BeSupported#theboringracks#solarmounting
