1. Construction scaffolding steel pipes, construction scaffolding pipes for construction of scaffolding attachments, scaffolding caps for steel scaffolding 2 and scaffolding steel lengths: transect 513. 0 mm; appropriate 483. 5 steel tubes. Maximum length: horizontal horizontal pole 2,200 mm, other pole 6,500 mm. Inspection items: stretching, bending, size deviation, surface mass, weight, rust, etc. 5. Sampling: (1) when applying a straight-point welding tube, 400 sets of samples are used, and four (two stretching tests, approximately 500 mm long; two bending tests, about 500 mm long) are to be tested in terms of mechanics, while other project tests are to be tested one by one and not less than five. (2) when using low-pressure fluid transport welded steel tubes, with a batch of 750 samples for mechanical performance testing of two samples (one stretch test, approximately 500 mm long; one curved test, approximately 500 mm long), of which the project test
2. No less than five examinations shall be carried out on a root basis. 9. Review rules: unqualified persons should be singled out when an indicator does not meet the standard requirements, and double-number samples should be obtained from the same steel tubes for the re-examination of an ineligible item. 1. 2 the scaffold attachments are broken down into straight-angle attachments (z), rotation attachments (u) and attachments (d), bottom (dz)6 and detection items: smoothing, damage, steel reversals, and tractor resistance. 7. Sampling: (i) 8 for 281-500 batches; 13 for 501-1200 batches; and 20 for 1201-10000 batches. (2) the number of samples, by type, as specified above. (3) random sampling of inspected products. 2 seat cap 1, test project: impact absorption and puncture resistance. Sampling: (1) lot
3, 2000-20000 in number, less than 2,000 in number. (2) six per batch (2 for inspection and 4 for backup). 3. Review rules: if there is one non-conformity, double-checking is not, and the product is not. Arrest code: gk type code: z or u or d master parameter: z or u or d, e. G. 48 variant code: a. B.
