Spray tables are used for spraying pieces with finishing materials. They are typically made of metal or plastic and have a flat surface with raised edges to contain overspray. They are also designed to be easy to clean and can be used with a variety of finishing materials, including paints, varnishes, and lacquers.

MC&P are conveniently located in the North West of England. We are 15 minutes’ drive from J23 of the M6 or J7 of the M62, and 10 minutes from the A580 East Lancashire Road. We work with a wide variety of customers across the UK – from small retail businesses, to large commercial and government organisations – all of them trust MC&P for their handling needs. AAMA 502 11 and AAMA 503 12 specifications both utilize the procedures outlined in ASTM E1105. There are, however, a few notable differences between AAMA 502 and AAMA 503. Additionally, AAMA 511 1 includes several testing techniques, including ASTM E1105. The differences among these three AAMA standards are outlined in Table 1. The reasoning here is that performance testing is intended to meet a certain standard and requires a higher degree of care to implement, quantify results, and document findings. Conversely, troubleshooting to determine the cause of an existing problem can involve just about any form of testing, so long as the conclusion reasonably reflects the observations and is properly documented. An additional point is that all AAMA tests require an AAMA-accredited independent testing agency (see guidelines in AAMA 204 20). AAMA tests conducted by nonaccredited agencies should therefore be considered “modified” as they do not comply with the accreditation requirement.

As a general rule for any tiered or staged water testing, the lowest area under consideration should be tested first. This is explained in both AAMA 501.2 5 and ASTM E2128. 2 As noted in ASTM E2128, “starting at the bottom helps eliminate ambiguity about the origin of a leak that might result from water running vertically down the surface of the test area.” Additionally, testers should take care to not overspray the area being tested, as this can lead to false positives and misunderstood results.

It should be noted that the ASTM E1105 appendix mentions that the water-spray volume is not tied to a specific rain event. In fact, the comparison between any given event and water-spray volume is misleading. The water spray is intended to fully and uniformly wet the entire exterior for the duration of the test. This purpose ultimately leads to an overwhelmed weep system, which is then exacerbated by the differential pressure. This test is intended to completely inundate the specimen’s water management system and is not “intended to reproduce or simulate any given rain event.” For windows with sills that can collect water, the test will necessarily produce standing water (in the sill), whose depth is proportional to the differential pressure applied.

It goes beyond drawing details and specifying products, allowing the consultant to work with hoses, test nozzles, and brass and polyvinyl chloride (PVC) equipment. There is an aspect of hands-on puzzle solving that mirrors the design process but can’t be replicated in an office. It can be a messy, frustrating, exhausting, and rewarding job.
