CONTAMINATION
Payload contamination must meet the requirements in Table 3-14. Verification Customer is responsible for verifying compliance to this requirement in the form of a Payload contamination report.
Table 3-14: Payload Contamination Requirements
Name Description Visual Cleanliness Payloads must be cleaned to VC-HS standards per NASA-SN-C-005D prior to integration onto Launch Vehicle hardware.
Non-Metallic Materials Each individual nonmetallic material used in the construction of the Payload that will be exposed to vacuum must not exceed a total mass loss of 1.0% and the volatile condensable matter must be less than 0.1% when tested per ASTM E. This would include avoiding use of markers, pens, and paint pens to mark Payload hardware. A complete vacuum-exposed nonmetallic materials list including quantities (surface area or mass) will be delivered to SpaceX for review. Any exceedances will be evaluated and approved on a case-by-case basis. Metallic Materials The selection of metallic materials by the Customer will include consideration of corrosion, wear products, shedding, and flaking in order to reduce particulate contamination. Dissimilar metals in contact will be avoided unless adequately protected against galvanic corrosion. Payload Particulate Generation The Payload will not create particulate during the vibroacoustic ascent environment. Actuation of any Payload mechanisms nearby any Co-Payload(s) or Launch Vehicle Hardware must not create particulate. Payload Deployment The Payload deployment system will not include the use of uncontained pyrotechnics (e.g. Frangible nuts. Payload Propulsion Payload propulsion systems will not be operated in close proximity (within 1 km) of Co-Payload(s). Prohibited Materials The following materials are not to be used on Payload hardware cadmium parts
•
cadmium-plated parts zinc plating mercury, compounds containing mercury pure tin or tin electroplate (except when alloyed with lead, antimony, or bismuth) Silicone Sensitivity All silicone rubber or RTV silicones with probability of transfer to Co-Payload(s) or Launch Vehicle hardware will require SpaceX approval, coordination, and notification prior to use.
