Aluminum alloy profiles GB5237. 1~5-2008 ~ 5-2008 are from the same manufacturer, the same brand, the same state, the same specification and the same surface treatment method. Each batch takes 2 profiles, and each profile takes 1 sample. (Thermal insulation profiles: take 4 profiles in each batch, each 1 sample. ) Sample length: 1m, ***2 segments. (Insulation profile: 1m***4)
The PVC profile GB/T88 14-2004 for door and window frames is produced by the same manufacturer, with the same raw materials, process, formula and specifications, and the quantity does not exceed 50t. Three sections are randomly selected from each batch, and then cut from these three sections. Sample length: 1m, ***5 segments.

Sample management program
working procedure
On-site sampling personnel shall mark and label the collected samples in time. Label identification should include information such as sampling location, analysis items and sample number.
According to the requirements of sampling specifications, it should be properly kept and transported safely. If fixative is needed, it should be added on site. If it needs to be stored at low temperature or in the dark, it should be stored at low temperature or in the dark immediately (including during transportation) to prevent pollution, deterioration and damage during transportation.
On-site sampling personnel will hand over the samples to the sample management personnel, and both parties will sign the sample handover record for confirmation. For the samples entrusted by customers, the comprehensive technical office shall hand them over to the management personnel of the monitoring and analysis office, and sign the sample handover record for confirmation. After receiving the sample, the sample manager should check the status of the sample and fill in the sample handover record.
Indicate the number, quantity, characteristics, status and abnormality of the sample, add the laboratory number to the received sample, hand it over to the analyst in time, and explain whether to keep the sample. The laboratory numbers are arranged in sequence. After adding the sampling numbers, the laboratory numbers are updated once a year.
Because of special requirements, the filter cartridge for measuring particulate matter from pollution sources (including smoke and dust) and the filter membrane for measuring particulate matter in the air are numbered by the sample administrator first, and then handed over to the sampler for weighing and sampling. Numbers are numbered sequentially and updated once a year.
For the added quality control samples, the sample administrator should carry out indoor password and compilation according to the sampling number.
In the process of sample preparation and analysis, analysts should strictly control environmental conditions, protect samples, and avoid confusion, loss and deterioration.
The analyst shall mark the analyzed items with the symbol "X" in time. After all the samples are analyzed and tested, the analyst should treat the samples that do not need to be preserved according to the "Three Wastes Treatment Regulations".
Samples for supervisory monitoring and arbitration monitoring and samples required to be preserved by customers shall be collected by the sample management personnel after inspection, and shall be properly preserved in accordance with the requirements for sample preservation within the validity period of preservation, and shall be properly disposed of after the expiration.
The sample handover record shall be kept and filed by the sample administrator, and shall be implemented according to the Document Management Procedure.
